Abstract. In this study, a multi-period, multi-objective mathematical model is presented for selecting oil and
gas investment projects based on the Sustainable Development Goals (SDGs) approach, considering resource lim-
itations. Based on the economic dimension of sustainability, the profit from the implementation of petrochemical
projects is maximized, and based on the environmental dimension, the amount of greenhouse gas emissions, energy
consumption, and produced waste is minimized. According to the social dimension, the number of job opportu-
nities, the number of people covered by insurance, the job satisfaction of employees, the project’s impact on the
regional economy, and the number of lost workdays is examined. The uncertainty of the strategic and operational
parameters of the model has also been considered, and to deal with the uncertainty, fuzzy possibility programming
(FPP) is used. The model is solved in GAMS optimization software with a two-stage approach based on fuzzy
programming and the best-worst group decision-making method (BWM). Numerical results confirm the effective-
ness of the proposed model and show that SDG will lead to a significant improvement in economic, environmental,
and social dimensions without significantly reducing the profits of the selected oil and gas projects.

1 Introduction
Organizations’ managers are always faced with conflicts in making decisions at different strategic
and operational levels (Davardoost & Javadi, 2019) the quality and manner of these decisions will
guarantee the success and survival of organizations in the field of business and will overshadow
their competitive position. One of the critical determinations made by managers in petrochemi-
cal organisations is the selection of an optimal portfolio of investment projects from the available
options. In the absence of quantitative and economic methodologies guiding the project selection
process, there is a risk of misalignment between project outcomes and initial expectations, result-
ing in significant costs for both organizations and contractors. It is imperative for managers to
employ mathematical optimization models to arrive at optimal decisions, thereby enabling them

to quantitatively assess the outcomes of their decision-making and available options. Hence, the
application of mathematical modelling in the assessment of oil and gas projects is of considerable
importance for managers functioning in this sector. Through the utilization of the most efficient
solution obtained from the mathematical model, managers can augment their capacity to make
informed decisions (Afanasyev et al., 2023; Bilbao-Terol et al., 2006; Golmakani & Fazel, 2011;
Kukharova et al., 2021; Liu & Gao, 2006). In general, the goal of the project selection problem
is to choose an optimal portfolio of several selected projects according to the limitations of time,
machinery, power, human capital, and other available facilities to achieve optimal goals. One
of the important and commonly used goals in this field is to maximize the profit of the project
and minimize the costs. Considering that the selection of oil and gas investment projects is
one of the most important organization’s decisions, paying attention only to the goals of the
internal project stakeholders, such as the project sponsor, the employer, contractors, the project
managers, the project consultant, and the main external stakeholders of the project, cannot be
of great benefit to the managers and companies. Therefore, it cannot ensure the success and
survival of the organization in the business environment. If an organization or company acts only
based on profit to decide regarding the selection of the project and the satisfaction of the external
stakeholders of the project, such as competitors, media, legislative organizations, environmen-
talists, sub-stakeholders, society, and citizens, if they do not pay attention, they may face a
challenge in the long run. Therefore, to fulfill the main goals of managers in choosing investment
projects, it is necessary to model the problem from the perspective of both internal and external
stakeholders of the project. Carrying out any project requires the consumption of various re-
newable and non-renewable resources such as manpower, machinery, raw materials, and required
equipment (Arefiev & Afanaseva, 2022). It is noteworthy that the execution of any oil and gas
venture results in the emission of greenhouse gases into the atmosphere (Fetisov et al., 2023;
Litvinenko et al., 2020; Pashkevich & Danilov, 2023). In recent years, there has been a growing
global awareness of pollution control in response to production and industrial activities, driven
by a desire to preserve land and its resources, promote economic development, ensure social wel-
fare, protect the environment, and enhance community security (Fetisov et al., 2023; Ilyushin,
2022; Ilyushin & Fetisov, 2022; Litvinenko et al., 2023). According to the available statistics
and reports, the emission of greenhouse gases around the world has increased by more than 80%
from 1970 to 2010, which is considered a great threat to the global ecosystem (Martirosyan &
Ilyushin, 2022). To reduce greenhouse gas emissions, different international agreements have
been made. For example, China and the United States, as the largest emitters of carbon dioxide
(CO2), announced their joint announcement on climate change in 2014 and policies to reduce
greenhouse gas emissions. Then, at the United Nations (UN) Climate Conference in 2015, a new
global agreement was made in which all participants pledged to reduce greenhouse gas emissions
to zero (Chen & Chen, 2017; Yurak et al., 2020). In light of growing environmental concerns,
business managers have devoted a significant portion of their efforts to executing effective invest-
ment projects that account for environmental considerations, in order to address these concerns
(Martirosyan et al., 2021) by implementing projects in addition to increasing profitable sales and
reducing costs (Kazanin & Drebenshtedt, 2017; Perdan & Azapagic, 2011).
Conversely, in the context of executing an investment initiative project, the organization’s
social responsibility towards employees, customers, and society should be considered with social
goals such as increasing job opportunities, stabilizing employment, and reducing the number
of injuries and lost days due to work accidents (Ilyushin et al., 2019; Moreno-Monsalve et al.,
2023). In recent years, there has been an increased focus on the concept of sustainability, which
involves balancing economic, social, and environmental requirements. With the growth of the
world population and the increase of human activity, sustainability has become an important issue
for governments, people, and environmentalists. Using sustainable development management for
organizations will have many benefits, including customer satisfaction, cost control, innovation,
and flexibility (Moreno-Monsalve et al., 2023; Rohmer et al., 2019; Sahebjamnia et al., 2018;
503
ADVANCED MATHEMATICAL MODELS & APPLICATIONS, V.8, N.3, 2023
Taleizadeh et al., 2019). Although much research has been conducted in the field of investment
project selection, based on the results of the research background, limited research has been
conducted in the field of investment project selection according to Sustainable Development
Goals (SDGs). On the other hand, the decisions about selecting oil and gas investment projects
are among the strategic decisions of petrochemical organizations that are faced with considerable
uncertainty. The project selection problem encompasses numerous parameters, including the
potential profit yielded by project implementation, the availability of manpower, the quantity of
machines and raw materials necessary, the precise timing of activities, the requisite budget, and
the costs associated with both manpower and raw materials. The requirement for the machine’s
cost is faced with significant uncertainty (Teplyakova et al., 2022). Considering these parameters
in a certain way, the optimal solution to the problem may not be justified in real conditions.
Ben-Tal & Nemirovski (2000) demonstrated that even with a mere 0.001% uncertainty in the
parameters, the optimal solution derived from deterministic data is not sufficiently justified with
a significant probability. Consequently, the constraints of the problem may be violated. Hence,
it appears imperative to scrutinize the ambiguity surrounding the choice of investment ventures
(Ben-Tal & Nemirovski, 2000).
The aim of this research is to provide a mathematical model for selecting investment oil and
gas projects based on SDGs and considering the parameter’s uncertainty. In this model, the
goals of profit maximization, environmental impact minimization, and social impact maximiza-
tion will be considered simultaneously. Since the available resources for the implementation of
petrochemical projects are limited, in the mathematical model, the total budget available in a
period will be considered limited, and the real world’s limitations such as manpower, machines,
and consumable resources will also be considered. Decision-making related to the selection of
petrochemical projects is considered over a multi-period time horizon, and the investment and
selection of those projects in each period will be examined separately.
The advantage of a multi-period, multi-objective mathematical model for selecting oil and gas
investment projects compared with existing ones lies in its ability to comprehensively consider
various factors and objectives over time, leading to more informed and strategic decision-making.
This approach integrates multiple criteria and time periods, allowing for a holistic evaluation of
investment projects. The previous studies also emphasize the advantages of rule-oriented models
in decision support systems for oil and gas production companies, highlighting the need to utilize
knowledge base rule-oriented models for decision-making. This aligns with the multi-objective
nature of investment project selection, as it requires the consideration of diverse rules and criteria.
Furthermore, it underscores the adaptability of techniques preferred by organizations, indicating
that the multi-period, multi-objective mathematical model can be tailored to suit the specific
preferences and needs of the oil and gas company.
In conclusion, the advantage of the multi-period, multi-objective mathematical model for
selecting oil and gas investment projects compared with existing ones lies in its comprehensive
consideration of diverse criteria, rules, and time periods, leading to more robust and informed
decision-making processes.

2 Research background
In the literature on the selection of investment projects, various mathematical models have
been developed for the selection of projects. This section provides a comprehensive review
of the literature pertaining to the process of selecting investment projects. For this purpose,
Table 1 presented below provides a summary of the solving methods proposed by scholars. It is
noteworthy to mention that in the selection of investment projects, since numerous parameters
of the real world are subject to uncertainty, mathematical modeling also takes uncertainty into
account. To investigate uncertainty, various methods such as Monte Carlo simulation, stochastic
programming, fuzzy theory, robust optimization, and hybrid approaches have been used.
While SDGs have been the subject of numerous research articles in recent years, the matter
of selecting oil and gas investment projects has received comparatively less attention. Therefore,
the characteristics of the reviewed articles are shown in Table 2. As can be seen in most of the
research, only the economic dimension in the selection of projects with the aim of minimizing
the implementation costs or maximizing the profit from the implementation of the project has
been investigated, and other main dimensions of the SDGs, including environmental and social
dimensions, have received less attention. Among the reviewed articles, only Habibi et al. (Habibi
et al., 2019) used SDGs to select the suppliers of materials needed for the projects, and Reza
Hosseini et al. (RezaHoseini et al., 2020) used SDGs to determine the desirability of the selected
projects. Although in the real world it is rare to determine the exact value of the parameters,
in most of the articles the parameters are assumed to be definite. Also, among the various
methods to deal with the uncertainty of parameters, areas such as possible fuzzy optimization
have not been considered at all. Interrelationships between projects have not been investigated
in most studies. In this research, a model for selecting oil and gas investment projects based
on SDGs is proposed in conditions of uncertainty, given the interdependent nature of projects
and resource constraints, the present study proposes a model that innovatively addresses these
factors as below which is mostly modeled on Zarinpour’s work:
1. Providing a mathematical framework for the selection of petrochemical investment projects
over a multi-period time horizon. The model considers various real-world constraints,
including budgetary limitations, manpower availability, machinery capacity, raw material
availability, and supplier capacity,
2. Investigating mutual relationships between projects using complementary economic con-
straints and incompatible options at the same time,
3. Examining the SDGs in the selection of oil and gas investment projects, including the
economic, environmental, and social goals,
4. Examining job opportunities, injuries, and lost days due to work accidents, the number
of people covered by insurance, the impact of project selection on the improvement of the
regional economy, and the social welfare of employees in the function of the social goal,
5. Investigating greenhouse gas emissions, energy consumption, and waste produced in the
review function for environmental purposes,
6. Investigating the uncertainty of real-world parameters and using the fuzzy possibility ap-
proach based on the "Me" criterion to deal with uncertainty in the project selection prob-
lem,
7. Using a combined solution approach, including the Best-Worst group method (BWM) to
determine the weight of environmental and social factors and the interactive fuzzy pro-
gramming method to solve the multi-objective mathematical model.

3.1 Statement of the problem
In this research, a multi-objective mathematical model is presented for choosing investment oil
and gas projects using the SDGs approach. Since the available resources for the project’s imple-
mentation are limited, in the mathematical model, the total available budget is considered for
a limited period, and other real-world limitations such as manpower, machinery (Yungmeister
et al., 2021), and consumables are also considered respectively (Yungmeyster et al., 2022). The
amount of investment and the projects chosen for each period are both determined based on the
decisions made in relation to the selection of projects, which are made with a long-term time hori-
zon. In the proposed model, the interrelationships between the projects, the uncertainty of the
parameters, and the project’s raw material suppliers’ capacity are examined. The assumptions
of the proposed problem are as follows:
1. Decisions related to the selection of projects can be made over several time periods.
2. Complementary economic restrictions are considered in the selection of investment projects.
3. The manpower and raw materials required to carry out investment projects and project’s
raw material suppliers’ capacity in each of the time periods is limited.
4. Some investment projects have incompatible options, so by choosing one of them, the next
incompatible option will be removed.
5. The uncertainty in the model parameters is considered.
The sets defined in the mathematical model are as follows:
507
ADVANCED MATHEMATICAL MODELS & APPLICATIONS, V.8, N.3, 2023
J: set of existing projects;
T: set of time periods;
R: set of raw materials;
M: set of machines;
L: set of human resources;
S: set of suppliers;
K: set of amenities for employees;
Hj: set of incompatible projects with the project j
Ej: set of economic complementary projects of project j.
3.2 Economical objective function
The main goal of choosing oil and gas investment projects is to maximize the profit, which is as
follow:
Max Z1=T R T C, (1)
where the total revenue from the selection of projects is marked with T R and the total cost of
implementing the projects is marked with T C, which expression 2 is considered as below:
T R =X
jX
t
˜pjt xjt ,(2)
where ˜pjt is the expected profit of the project jat time tand xj t is a binary variable, where
it is equal to 1 if project j is selected at time t, otherwise it is considered zero. To calculate
T C total system costs including fixed investment, raw material supply, manpower, machinery,
travel, and amenities costs are considered. The fixed investment cost of the project can comprise
of expenses related to the acquisition of equipment and machinery essential for the project’s
execution, infrastructure development, land procurement, construction of buildings, landscaping,
and procurement of vehicles, and the cost of issuing permits and initial feasibility studies. This
type of cost is expressed according to expression :
X
jX
t
˜
F cjt xjt ,(3)
where ˜
F cjt is the fixed investment cost to implement project jat time t.
The cost of supplying raw materials consists of the purchase cost and the cost of ordering
raw materials which are procured from different suppliers. The cost of supplying raw materials
is calculated using expression 4:

ordering raw material rsupplied by supplier sat a time t, and ursjt is the binary variable that is
equal to 1 if supplier sis selected to supply raw material type rfor project jat time t, otherwise
it is considered zero.
To implement the project, the cost of manpower is calculated based on the man-hour accord-
ing to the following expression 5:
X
lX

˜

where ˜
lclt is the cost per hour of labor lat time tand whlis the working hours of labor type l
in each period.

Also, the cost of machines is calculated based on machine-hours required for the implemen-
tation of the project according to expression 6:
X

˜
Mcmt whmxj t,(6)
where ˜
Mcmt is the cost per hour of machine type mat time tand whmis the working hours of

Furthermore, the cost for transporting raw materials from the supplier to the project site is
calculated according to the following expression 7:
X
rX
sX
jX
t
˜
T crsjt dsj yrsj t,(7)
where ˜
T crsjt is the transportation cost of the raw material type rfrom the supplier sfor the

project implementation site j.
Finally, the cost of amenities for the employees involved in the project is also calculated
according to the following: X

jX
t
˜

where ˜
Sckjt is the cost of providing any type of amenities kfor project employees jat time tand
okjt is the binary variable equal to 1 in case of providing any type of amenities kfor the project
employees jat time t, and otherwise zero.
Considering that in evaluating the economic feasibility of the projects the period and the time
value of money are very effective factors, the concept of discount rate has been used. According
to the provided information, it can be inferred that the first expression will be elaborated in the

3.3 Environmental objective function
To execute a project, it is imperative to procure requisite raw materials, which necessitates
the utilization of vehicles for the purpose of transporting materials from suppliers. The trans-
portation of raw materials results in the emission of significant quantities of greenhouse gases,
including carbon dioxide, methane, sulfur dioxide, nitrogen oxide, heavy metals, and volatile
organic compounds (Fetisov et al., 2023). These emissions pose a severe threat to human health.
The emission of greenhouse gases resulting from the combustion of fossil fuels is widely recognized
as the primary contributor to global warming and consequential alterations in the Earth’s climate
and soil (Martirosyan & Ilyushin, 2022; Shammazov et al., 2023; Vasilyeva, 2023; Zhang et al.,
2018). Conversely, the transportation of raw materials by vehicles necessitates the utilization
of fossil fuels. The global populace’s requirement for non-renewable energy sources is escalating
at a rapid pace, surpassing the capacity of current energy reservoirs to cater to this mounting
509
ADVANCED MATHEMATICAL MODELS & APPLICATIONS, V.8, N.3, 2023
demand. According to a projection (Mirhosseini et al., 2011), the global energy demand is ex-
pected to increase twofold or even threefold by the year 2050. As per the prognostications, the
worldwide utilization of oil is anticipated to escalate from 86 million barrels per diem in 2007
to 104 million barrels per day in 2030 (Brink & Marx, 2013; Ilyushin & Asadulagi, 2023). The
preservation of fossil fuels has become an imperative need considering their depletion and the
pressing environmental issues (Afanaseva et al., 2023; Kazakov et al., 2022).
To mitigate the quantity of greenhouse gas emissions resulting from the conveyance of raw
materials, the fuel consumption associated with the transportation of materials from suppliers
to the designated project site, and the waste generated by the utilization of raw materials in the
chosen projects, we shall employ expressions 10, 11, and 12, correspondingly.

3.4 Social objective function
With the implementation of any investment project, the organization’s social responsibility to-
wards internal and external stakeholders should be considered. The GRI report [36] has been
used to consider the social dimension. One of the most important responsibilities of investors to-
wards society is to increase the number of job opportunities. To implement an investment project,
different human resources, such as project sponsors, employers, project managers, project con-
sultants, project contractors, main project shareholders, and workers, are needed. It is worth
noting that some of the required labor force is required on a constant basis from the beginning to
the end of the project, but some of them will be employed for a short period of time. The number
of fixed and variable job opportunities created by selecting investment projects is calculated as
expressions (14) and (15). Then, the number of idle working days that are lost due to injuries
and work hazards is calculated as belowX

Given that project employers and contractors frequently hire erratic labor for numerous
projects, insurance typically covers a small number of people. Therefore, to increase the number
of people covered by insurance (objective function 17), to improve the economic situation of
the project implementation area (objective function 18), and to increase the level of employee
satisfaction, considering welfare amenities (objective function 19) as parts of the social objective
function is considered respectively:

Constraint 21 guarantees that each project is selected only once in each period. According to
constraint 22, each project must be completed within the planned time horizon. Constraint 23
specifies that the total raw materials required to carry out the selected projects should not exceed
the available raw materials in any period (e
λrj is the required type rraw material for the project
jin each period, and βrt is the amount of primary material type rat time t). Constraint 24
states that the working hours of the machines required for the selected projects do not exceed
the available machine-hours in any period (eγmj is the required machine-hours type mfor project
jin each period, and e
δmt is machine-hours available type mat time t). Based on the constraint
25, the man-hours required to carry out the selected projects do not exceed the available man-
hours in any period (eτlj is the number of man-hours required for labor lfor project jin each
period, and e
lt is man-hours available type lat time t). Constraint 26 is related to incompatible
project options: if the projects are incompatible, only one of them will be selected. Constraint 27
expresses the restriction of economic complementarity between projects. Constraint 28 specifies
that in each project, the total raw materials purchased from suppliers are equal to the raw
materials needed to complete that project. Constraint 29 specifies that the total raw material
purchased from suppliers is equal to the available raw material in each period. According to
the constraint 30, the number of raw materials purchased must be less than the capacity of the
suppliers. Constraint 31 specifies that only if a project is selected, suppliers will be selected
to provide raw materials. The constraint of 32 to 36 specifies the constraints of the problem’s
decision variables.

4 A probabilistic fuzzy programming approach
In the previous section’s proposed model, some parameters are uncertain. Approaches such as
random optimization (RO), fuzzy optimization (FO), stable optimization, and hybrid approaches
can be used to deal with parameter uncertainty. In this study, the fuzzy optimization method
(FOM) is used to deal with the uncertainty in the parameters of the model. In fuzzy mathematical
programming (FMP) models, fuzzy confidence coefficients and membership functions are used
to express the uncertainty of parameters (Xu & Zhou, 2013; Zarrinpoor et al., 2018). Numerous
researchers have used the fuzzy-probabilistic method that Xu and Zhou (Xu & Zhou, 2013)
first proposed because of its widespread success. This method relies on strong mathematical
concepts such as expected distance and the expected value of fuzzy numbers. In this method,
it is assumed that all non-deterministic parameters follow the triangular distribution function.
Consider the possibility space (θ, P (θ), P oS ) where θ, P (θ),and P oS specify an arbitrary
set, a set function of θ, and a possibility criterion, respectively. To determine the values of non-
deterministic parameters between optimistic and pessimistic constraints, Xu, and Zhou (Zhang
et al., 2018) used the Me criterion as follow:
M e (A) = Nec (A) + ς(P os (A)N ec (A)) ,(37)
where A is an arbitrary set in P(θ),and ςis an optimistic-pessimistic parameter that reflects the
decision-makers opinions. Functions P os (A) and N ec (A)specify the necessity and possibility
of set Ain probabilistic space, respectively. In the following, the approach of Xu and Zhou
(2013) is briefly described. Consider the following linear programming model:
Min ˜
Cx
˜
Ax ˜
b
˜
Nx ˜
d
x0.
(38)
In this model, non-deterministic parameters are considered triangular fuzzy numbers (TFN). In
probabilistic planning based on criterion 1, the functions of expected value, chance limit, and
possibility limit are used. So, we have:
Min ˜
Cx
M e {˜
Ax ˜
b} α
M e {˜
Nx ˜
d} β
x0,
(39)
where αand βare the minimum levels of satisfying the possible constraints. Xu, and Zhou
converted the above model into upper approximation model (UAM) and a lower approxima-
tion model (LAM), and then, they proposed the deterministic equivalent (DE) model of the
probabilistic models UAM and LAM, which are as follows:
Upper Approximation Model (UAM)
M in E[˜
C]x
P os {˜
Ax ˜
b} α
P os {˜

5 Solution method
In this study, a two-step solution method is used. In the first stage, the importance of envi-
ronmental and social criteria is determined using the best-worst method (BWM). In the second
step, an interactive fuzzy programming method will be used to transform the multi-objective
mathematical programming problem into a single-objective problem.

5.1 The Best-Worst Method (BWM)
BWM was introduced in 2015 to determine the weight of decision-making problem criteria
(Rezaei, 2015). In this study, considering that this method only uses the preferences of a decision
maker, to determine the weight of the criteria based on the opinions of a group of decision mak-
ers, the BWM of Omrani et al. (2020) has been used. The steps of this method are summarized
as follows:
1. Step 1. Determine the important criteria for the decision problem.
2. Step 2. determine the best and worst criteria from each decision maker’s perspective.
3. Step 3. Specify the preference of the best criterion (B) over the rest of the criteria based
on the opinion of the decision maker (r) with numbers 1 to 9 as follows:
Ar
B= (ar
B1, ar
B2, . . . , ar
Bn).(59)
4. Step 4. Specify the preference of other criteria over the worst criteria (W) based on the
decision maker’s opinion (r) with numbers 1 to 9 as follows:
Ar
W= (ar
1W, ar
2W, . . . , ar

5. Step 5. Considering ar

the opinion of decision maker rand ar

5.2 Interactive fuzzy programming (IFP) method
To solve multi-objective problems, there are various methods, such as the Epsilon constrained
method (ECM), the LP-metric method, and the weighted sum method (WSM). In this study,
the interactive fuzzy programming method (IFPM) proposed by Torabi and Hassini (Torabi &
Hassini, 2008) is used to solve multi-objective problems. In this approach, positive ideal solutions
(PIS) and negative ideal solutions (NIS) for the objective functions of the problem are calculated
as follows:
ZP IS
1=Min Z1=M ax Z1, ZN I S

2=Max Z2=M in Z2, ZN I S

The linear membership function (LMF) for each of the objective functions is also defined as

$hµh(x)(77)
λ0µh(x),h(78)
xF(x), λ0, ϕ [0,1] .(79)
where $h,F(x)and ϕdetermine the relative importance of objective function h, the solution
space of the problem and the compensation coefficient, respectively. Also, λ0= minhµh(x)and
µh(x)determine the membership degrees of objective function h.
6 Numerical results
In this section, solution methods are used to explain the numerical results of the proposed model’s
solution. Table 3 shows the values of the input parameters in numerical examples. To determine
the weight of the components of the environmental and social objective functions, the opinions
of five experts in the field of investment projects were used.

Five different examples are used for numerical results. The model is coded in GAMS opti-
mization software (Released May 18, 2023). The size of the sets of numerical examples is shown
in Table 6, and the numerical results obtained from solving the model are shown in Table 7.
In Table 7, (DE) specifies the value of the objective function in linear mode. As can be seen,
the profit from the implementation of projects in all numerical examples in the UAM model is
greater than that in the LAM model. Because the UAM model is based on an optimistic view,
the profit from the implementation of projects (ς) increases with the increase in the optimistic
opinions of the decision makers. When the profit of the projects increases, more projects will
be selected, and more raw materials will be needed to implement the projects. Vehicles are
used to transport raw materials from suppliers to the project site which results in large amounts
518
D. PERVUKHIN et al.: A SUSTAINABLE DEVELOPMENT GOALS-BASED MATHEMATICAL...
of greenhouse gases and energy. Therefore, the value of the environmental objective function
increases. The value of the social objective function also increases in proportion to the profit of
the project. Because, when more projects are selected, more job opportunities will be created.
Since the focus is mostly on the economic dimension in the project selection models, the
impact of sustainability dimensions on the selection of investment projects has been investigated.
Table 8 shows the results based on the third numerical example. In this table, SM is a proposed
model based on SDGs, and PM is a model considering the maximization of expected profit. As
can be seen, considering the SDGs, the result of the economic objective function in deterministic
models (UAM and LAM) will decrease by 0.13%, 1.19%, and 0.13%, respectively, though it
will significantly improve the environmental and social objective functions. The destructive
environmental effects in the deterministic models (UAM and LAM) in the PM model are 2.31,
2.82, and 2.25 times of those of the model considering sustainability, respectively. The social
objective function of the deterministic and UAM models in the SM case has been improved by
95.4 and 98.97 percent, respectively, compared to the PM case. The social objective function of
LAM is also 2.06 times that of PM in the SM case.

7 Sensitivity analysis
This section presents an analysis of the variations in the objective function concerning the pa-
rameters of ϕ, discount rate (ir), available person-hours, and available machine-hours, utilizing
numerical example number 5.
7.1 The effect of ϕon the objective functions
To investigate the effect of ϕon the objective functions, the value of the degree of membership
in each function has been investigated. Table 9 shows the effect of ϕon the objective functions.
As can be seen, with the increase in the value of the membership degree of the first objective
function, the membership degree of the second objective function decreases and the membership
degree of the second objective function increases. The degree of membership in the third objective
function also has no special trend. Of course, in each of the deterministic models, UAM and
LAM, for some values of ϕ, the membership degree of the function remains unchanged. Also,
the results of the investigation of effect of ϕon the objective functions shows that results from
DE, UAM and LAM are convergent to 0.870 (Figure 1).

7.2 The Effect of discount rate (ir) on the objective functions
The effect of the discount rate (ir) on the objective functions is shown in Table 10 and figure
2. As can be seen, with the increase in the ir, the total profit decreases. Also, in some cases,
the environmental objective function and the social objective function are relatively reduced and
remain constant. It should be noted that the discount rate is one of the most influential param-
eters on the profit obtained from the oil and gas project’s implementation which by considering
it, a profitable project may be considered uneconomical. Considering that both the income and
expenses of the investor are affected by the discount rate (ir), profitable projects should be
selected according to the discount rate (ir) and the time factor (t).

The results of the analysis show that the closest exponential trend line for the objective
functions is y= 4E+ 09e0.178x, R2= 0.995 (Figure 2).

7.3 The impact of available machine-hours and maximum available
person-hours on objective functions
The impact of the maximum available machine hours is shown in Table 11. In this table, the first
column shows the percentage of maximum machine-hour changes compared to the base state. By
increasing the available machine hours in each period, more projects can be implemented, and
the profit from the implementation of investment projects in the oil and gas industry increases.
As the number of selected projects increases, the environmental objective function and the social
objective function also increase. In general, time is considered as an important factor in the
profitability of the selected oil and gas projects, and if the machine hours available in the initial
time periods of the project can provide the machine hours required by the project, a high profit
will be obtained for the investors.
Also, the effect of the maximum available man-hours is shown in Table 12. As it can be
seen, by increasing the maximum number of available man-hours, the necessary manpower to
complete the projects is provided in less time, and the projects become profitable sooner than
521
ADVANCED MATHEMATICAL MODELS & APPLICATIONS, V.8, N.3, 2023
expected. Furthermore, by increasing the maximum available man-hours compared to the base
case, as profitability increases, the economic impact of the project on the region and the number
of available job opportunities increase, and as a result, the social objective function increases
compared to the base case. With the increase in available man-hours, as more projects are
selected, the amount of energy consumption and greenhouse gas emissions will increase, and the
objective environmental function will increase, respectively.

8 Conclusion
In this study, the multi-objective planning problem of choosing investment projects considering
real-world limitations such as manpower, machinery, and consumables was presented. To select
investment projects, in addition to the economic objective function that maximizes the profit
from the implementation of the oil and gas projects, environmental and social objectives were also
considered. The proposed model was considered a multi-cycle mathematical programming model.
Based on the environmental dimension, the amount of greenhouse gas emissions, the amount of
energy consumed to provide the required raw materials, and the amount of waste produced
were minimized. Based on the social dimension, the number of job opportunities created by the
selected projects, the number of people covered by insurance, the job satisfaction of employees
because of the provision of welfare services, the impact of the project on the region’s economy,
and the number of lost working days were minimized. Also, the capacity of the suppliers to
provide the raw materials needed by the projects and the costs of purchasing and ordering the raw
materials were considered. Considering that in the real world, many parameters are uncertain and
random in nature, the uncertainty of the parameters was also considered. To transform the non-
deterministic model into a deterministic equivalent model, the fuzzy probability programming
approach based on the Me criterion was used, and two LAM and UAM models were developed. To
check the effectiveness of the proposed model, five different numerical examples were considered,
and the results were presented based on economic, social, and environmental objective functions.
In the end, the sensitivity analysis of the key parameters was presented.
Based on the numerical results, it can be stated that the presented mathematical model
provides a suitable tool for decision-making regarding the evaluation and selection of projects for
the senior managers of organizations and enables them to get the highest profit by choosing the
best set of projects and thereby overshadow their competitive position accordingly. Since the
UAM model is based on an optimistic view, in most of the numerical examples, the profit from
the implementation of the projects is greater than the LAM and the deterministic equivalent
model.
In UAM model, more projects are selected, so as the profit is higher, more energy will be
consumed and more greenhouse gases will be emitted, so the environmental objective function in
most numerical examples in UAM model is also higher than in LAM model. Also, UAM model
has a higher social objective function than LAM model and is a deterministic model. Therefore,
522

based on the numerical results, it can be stated that considering the SDGs will significantly
improve the environmental and social dimensions of sustainability without having a significant
impact on the profit of the project’s implementation.
The results of this research show that if there is uncertainty in the model’s parameters, they
cannot be ignored. Because, the profitability of the investor is greatly affected, and the amount
of profit will be less or more than the actual amount. The discount rate (ir) is one of the most
influential parameters in investment; considering it, an economic project has a chance to may
be considered uneconomical. Therefore, its exact amount should be determined according to the
type of project so that the investor can choose profitable projects in the shortest possible time. In
general, by increasing the maximum machine hours and the maximum person hours available, it
becomes possible to carry out investment projects in a shorter period, and consequently, the profit
from the project’s implementation increases. Therefore, to design an effective project selection
mathematical model, it is necessary to consider real-world constraints such as renewable and
non-renewable resources for the implementation of projects to obtain an accurate estimate of the
implementing projects’ benefit.
9 Recommendations for the future research
According to the proposed model in this article, future research directions for researchers in the
fields of investment and project management are suggested as follows:
In the proposed model, the maximum machine-hour and person-hour available in each period
are considered parameters. It would be very interesting for future research to consider these
parameters as decision variables. In the proposed model, the effect of loans, sanctions, currency
exchange rate, and other financing sources on the implementation of projects can be considered.
In this study, fuzzy probabilistic programming was used to deal with uncertainty. For future
research, other approaches such as robust optimization and stochastic planning (logic-based
Bender’s decomposition (LBBD) can be used to deal with uncertainty and compare the results
with the possible fuzzy planning approach.

Pipeline transportation is widely regarded as the most cost-effective method for conveying substantial volumes of hydrogen across extensive distances. However, before hydrogen can be widely used, a new pipeline network must be built to reliably supply industrial users. An alternative way to rather expensive investments in new infrastructure could be to use the existing pipeline network to add pure hydrogen to natural gas and further transport the gas mixture in an industrially safe way. The new solution necessities will be examined for compression, transportation, and fire hazard accidents, which have not been scrutinized by other scholars. This study presents the results of a comprehensive analysis of the methane–hydrogen mixture compression process and a mathematical description of the main pipeline operation during gas mixture transportation, considering industrial fire safety issues. By examining a case study involving a main gas pipeline and its associated mathematical model for hydrogen transportation, it becomes feasible to assess the potential hazards associated with various leakage areas and the subsequent occurrence of fires. The findings of this investigation demonstrate that the spontaneous combustion of hydrogen due to leakage from a natural gas pipeline is directly influenced by the proportion of hydrogen present in the gas mixture. If the hydrogen percentage reaches a balanced ratio of 50–50%, it is plausible that the equipment at the compressor station could be subject to detrimental consequences, potentially leading to accidents and fires. Furthermore, the obtained results from modeling in ANSYS Fluent software propose two practical scenarios, which demonstrate that despite the limited research conducted on the safety aspects and the occurrence of fires during the operation of hydrogen gas pipelines, industrial and fire safety necessitate the inclusion of hydrogen transport infrastructure as a pivotal element within the broader framework of hydrogen infrastructure development.

The article discusses the method and results of processing statistical data from an experimental study of vibrations in marine diesel engines caused by the operation of cylinder-piston groups. The results of the application of a ranking method for identifying factors that influence vibration in marine diesel engines are presented to determine the most significant ones. A series of experiments were conducted according to special plans to actively implement the random balance method. This helped to establish the correctness of selecting the most significant factors from a variety of factors that influence the process under study. The article presents a mathematical model that enables the calculation of current values and prediction of changes in the most significant indicators, with the clearance between the piston and the cylinder liner being the most important.

The transportation of oil and gas in Russia’s northern and Arctic regions has seen significant growth in recent years. However, the presence of permafrost in these areas can cause malfunctions in the main pipelines due to soil frost heaving. The operational pipelines also often suffer from various defects in their body and surface. To mitigate these issues, above-ground trunkline supports are utilized to protect the pipelines from cryogenic processes. Nevertheless, these supports are subjected to ground loads caused by cryogenic frost heaving, which poses a threat to the pipeline’s integrity and the environment. In response to these challenges, this study presents a design for pipeline support to maintain the pipeline’s stability in the face of soil displacement caused by unequal frost-heaving forces. A numerical model was created to evaluate the fracture of frozen rock and the resulting stresses in the soil and support structure. The input data for the model includes coefficients that describe the soil’s state during the cryogenic process and the proposed support’s parameters. The experimental results showed the proposed design to be effective in protecting the pipeline from soil frost heaving. The paper also provides the results of numerical and experimental studies on soil fracture stresses depending on the rock type and temperature. This design promises to increase both the safety of above-ground trunk pipelines and their technological efficiency.

Uncontrolled, intensive extraction of water from mineral water deposits can lead to negative consequences, the penetration of sewage beyond the water-resistant layers, the destruction of the structure of aquifers and the further loss of the mineral water source. This paper deals with the issues of control of hydrodynamic processes under random impacts in the aquifers of mineral water deposits using mathematical models. The analysis of the technological process of mineral water extraction and statistical analysis of retrospective monitoring data of the deposit were carried out in order to confirm the hypothesis of the stationarity of the processes under consideration. A mathematical model of hydrogeological processes occurring under random disturbances has been constructed. The influence of such disturbances is expressed in deviations of the head in the aquifer from the desired value. Controlling consists of maintaining the head of aquifers at a given level in order to preserve the hydro-mineral base of the region. Lumped and distributed controllers are proposed as corrective blocks, the parameters of which are calculated by frequency methods of controller synthesis. The use of a closed loop control system minimizes the influence of random effects.

This paper is devoted to the study of the efficiency of solving logistic problems of mineral complexes by system modeling methods using the AnyLogic software environment. The oil terminal in St. Petersburg, which is a part of Russia's Multimodal Transportation System (MTS) in the North-West, was chosen as the study subject. A simulation model has been created in AnyLogic software that uses Agent-Based and Discrete Event Methods (ABM and DEM) A computational experiment was conducted based on the developed full-factor plan using a simulation model. The process of the terminal operation was optimized; as a result, to increase the absolute throughput capacity, it was proposed to increase the unloading speed, which will decrease the tankers' servicing time and thereby increase the throughput capacity practically twice. People have come up with ideas for how to put the technical solution into action. The main idea is to update the pipeline system and fittings so that they can pump oil products more quickly.

This study presents the results of capital and operating costs for CO2 capture technologies in the refining and petrochemical sectors. Depending on the refining process and the CO2 capture method, costs ofCO2emissions can be avoided from 30 to 40 Euros per tons ofCO2. Advanced low-temperature CO2 capture technologies for upgrading oxyfuel reformers may not provide significant long-term and short-term benefits compared to conventional technologies. For this reason, an analysis was conducted to estimate the CO2 reduction potential for the oil and gas in-dustry using short- and long-term ST/MT technologies, which was about 0.5–1 Gt/yr. The low cost of CO2 reduction comes from the good integration of CO2 capture into the oil production process. The results show that advanced gasoline fraction recovery with integrated CO2 capture can reduce the cost of petroleum product production and reduce CO2 emissions and partial CO2 capture can have comparative advantages in some cases.

The discipline of project management has been maturing over time, integrating positively with some organizational approaches, such as strategy and sustainable development, to meet current needs without risking future capabilities. In this sense, it is observed that measuring the success of a project only from the classic mechanistic perspective of the triple constraint: scope, time, and budget, is insufficient; this opens a space for a new variable of social progress: the creation of value. Thus, the objective of this study is to identify the degree of relationship between the success of the projects and the sustainable development approach, managing to determine through the results obtained some opportunities for improvement in light of the economic and organizational context. As a starting point for this research, a review of the literature associated with topics, such as sustainable development, value creation, and modern trends in project management, was carried out. The second step was to design and apply a structured survey to 148 Colombian companies that develop projects in different sectors, such as technology, infrastructure, and services. With the information collected, a structural equation modeling—SEM model was applied to determine the relationship between the selected variables. Finally, the results of this research showed that the success of a project that is carried out under a sustainable development approach has a positive tendency toward the creation of value. In conclusion, it is found that the four dimensions studied: impact, relevance, effectiveness, and efficiency, allow us to explain to a greater or lesser extent the success of the projects through their approach to sustainable development and value creation.

The impact of emissions from the fuel and energy sectors adversely affects the environment on the economies of countries. One of these pollutants is volatile organic compounds (VOCs), which contribute to the formation of tropospheric ozone. Emissions of hydrocarbon formation in the form of VOCs occur in four stages of the fuel and energy industry sector: (1) production, (2) processing, (3) transportation, and (4) storage. The oil and gas industry ranks among the top polluting industries in terms of VOC emissions. Research on the negative impact of VOCs, as well as CO2 emissions from the consequences of the extraction, processing, transport, and storage of oil and gas on the ecosystem of the planet and the population, has begun to be studied by science recently. Typically, these studies were conducted using laboratory and field analyses, as well as using data on anthropogenic emissions in the development of regulatory documents and requirements governing the control of VOC and CO2 emissions in the oil and gas industry. This paper presents a critical analysis of the literature on research on the negative effects of VOC emissions on the ecosystem and human health because of such factors as production, processing, transportation, and storage of hydrocarbons. This analysis shows the global magnitude of VOC emissions. Data from human‐made emissions from the oil and gas industry and direct emissions from transportation and energy processing were used to figure out how VOCs affect the environment around the world and how far they spread. In conclusion, this study found patterns of VOC emissions that show how important it is to control VOCs during the production, processing, transportation, and storage of oil and gas, as well as how important it is to create a single research base on emissions for each industry sector and on sources of greenhouse gas absorption.

Coal mining is still an important part of the global energy complex. Despite the active development of technologies and modern equipment, coal mining remains one of the most dangerous jobs in the world. The main danger is associated with a large number of the hard-predictable factors, such as the opening of a toxic and flammable gas blister, the collapse of a mine due to a violation of the mines’ structural integrity, etc. There are software and hardware systems capable of monitoring the necessary parameters, but the problem lies in the complexity and costliness of the implementation and maintenance, so even for the largest enterprises, the widespread implementation of such systems is unprofitable. Previously conducted studies have established that most of the developed coal mining monitoring systems are very expensive to implement and labor-consuming to use and support. This article proposes to consider the developed prototype of a system for toxic and flammable gases concentration real-time monitoring, capable of reading the information with sufficient speed and transferring it to a system which triggers the response mechanism in cases where the specified concentration limits would be exceeded.
