Abstract—In the new information and communication era,
digital transformation and adoption of recent technological
advances have become a must for all transport and logistics
providers who aim to significantly improve their activities.
Consequently, this digitalization is inevitably giving birth
to voluminous and rapidly growing sets of large-scale data
generated from heterogeneous data sources, also known as
Big Data. With particular management infrastructures and
advanced data analysis methodologies, these huge amounts of
data can be efficiently harvested to optimize the logistics and
transport operations and provide a higher quality of service.
This paper provides a review of the application of Big Data
technologies in improving the operational efficiency of transport
and logistics, exposes the main use cases and identifies some
future research challenges.

I. INT ROD UC TI ON
With the recent technical and scientific advancements in
information and communication technologies, and the prolif-
eration of use of sensors and connected devices, global data
sources have rapidly increased, leading to exponentially grow-
ing sets of data (see figure 1) [1]. This phenomenal generation
of massive data along with the opportunities it provides for
discovering new values and deriving new insights, and the
various challenges it attempts to raise in terms of analysis and
management, have created a new concept commonly referred
to as Big Data.
Logistics and Transportation sectors are among the most
ideally placed to take advantage of the analytical capabilities
and the methodological advancements of Big Data technolo-
gies. While managing the massive flows of individuals, freight
and goods, logistics and transportation services providers are
permanently creating vast and enormous datasets, especially
with the recent and continuous digitization of these sectors. For
millions of deliveries and shipments around the world every
day, content, location, weight, size, source and destination,
and many other information are getting tracked and collected
across the global transport and delivery network, presenting
thus multiple perspectives for applying Big Data analytics to
harvest all these large-scale data and provide new opportunities
in terms of service quality and operational efficiency.
The current paper aims to present a survey on Big Data op-
portunities in improving the operational efficiency of transport
and logistics. It is organized as follows. In section II, a general
overview of Big Data concept and technologies is provided,
defining terms and introducing some of the main aspects of Big
Data management and analytics. In section III, the different
types of data and the sensing modalities are exposed. In section
IV, the Big Data opportunities in improving the operational
efficiency of logistics and transport are analysed, with a review
of the main applications and use cases. A brief review of the
main perspectives and challenges Big Data technologies have
to raise in transport and logistics sectors is presented in section
V, before we conclude in section VI.

II. BI G DATA DEFINITIONS AND TECHNIQ UE S
Big Data generally refers to voluminous data which cannot
be managed with classical methods and techniques within
a tolerable time. Laney [2] presented the 3Vs Model to
define this concept of Big Data : Volume (a great volume
of data), Velocity (data rapidly generated) and Variety (data
with various natures and modalities). Later definitions added
other characteristics such as the Veracity (to emphasize the
uncertainty of data) and Value (a great value with a low
density) to introduce the 4Vs and 5Vs models [3].
This expanding and enormous quantity of data is generated
by a huge and increasing number of sources. The complexity
of modern life and human activities as well as the rapid ad-
vances in some scientific and technological fields such as elec-

tronic and communications, have leaded to the proliferation of
use of connected devices and ubiquitous networking, which
represent one of the major sources of data. Social Media,
enterprise data, healthcare systems, transport and logistics are
also sources of various types of information, generated at an
exponentially increasing rate and leading to huge amounts of
data sets.
Traditional Business Intelligence techniques and classical
processing and storage approaches were generally dedicated
to the management and analysis of structured Data (with
predefined formats). Yet, the sourced data in the Big Data
context are mostly unstructured data (without any defined
format) or a combination of both unstructured and structured
data (semi-structured), gathered from heterogeneous sources
including image, text, video and many types of data that
need novel methodologies in terms of processing, storage and
analysis.
A. Big Data Management Technologies
Due to the huge volume and the heterogeneity of Big Data,
new infrastructures must be used and a whole data manage-
ment process including more operations and pre-processing
steps must be carried out to derive the required business
insights and allow any data-driven decision making. Therefore
many new management platforms, tools and techniques, as
well as various new practices and user skills are being applied
and further investigated under the new Big Data Management
discipline [4]. A. Siddiqa et al.[5] proposed a general Big Data
management process flow consisting of four main elements as
illustrated in figure 2 :
-Data Storage : one of the fundamental concerns of Big
Data management is how to build systems with capacities
to store data on a petabyte scale. Such storage man-
agement systems are required to be capable of keeping
enough and sufficient data, improving its retrieval and
optimizing its availability to processing[6]. The storage
process is based on parallel activities to optimize the
storage operations.
-Data Pre-processing : in order to perform an efficient
data analysis, the data must first meet some quality
requirements. The pre-processing operations have the
main purpose of transforming inconsistent or incomplete
raw data into an understandable format ready for more
analysis process. Thus, they prepare data for further
processing by structuring them in a standard format to
obtain integrated data [7].
-Data Processing : The key step in Big Data management
process is the Data Processing. During this stage, insights
regarding the relationships between features are gained
which allows the development of effective analytics. It
includes various analysis methods, such as statistical
analysis, data mining and machine learning [8].
-Security : Due to the heterogeneity and multitude of data
sources in the big data environment, security is becoming
a more and more serious concern. Security involves
many issues such as privacy, integrity, confidentiality and
availability [5].
As for the infrastructures used in the Big Data management,
Cloud computing, which is an internet-based computing that
provides shared processing resources (application and services,
storage, servers, etc) [9], allows an important support to Big
Data management. The storage and computing resources can
also be expanded by replicating the current infrastructure and
clustering multiple additional nodes to create a distributed
environment and take advantages of parallelism (Scale Out),
instead of replacing the currently used technology with another
more powerful one (Scale Up) [10].
Big Data technologies are rapidly evolving thanks to the
increasing innovation activities in many information and com-
munication areas such as the Cloud Computing. A large
number of platforms and tools are being available for Big
Data analytics providing new distributed architectures and high
levels of memory and processing power. Big Data technologies
involve services and platforms for storage, processing and
security of data.
Fig. 2. Big Data Management Process
The Hadoop open-source framework, is a widely used
framework designed to manage large-scale data using a com-
modity hardware. It consists of a processing component :
MapReduce programming model, and a distributed storage
component : Hadoop Distributed File System (HDFS). The
HDFS storage approach consists in replicating the data into
multiple machines and storing them in blocks by a main server
(master node). On the other hand, the MapReduce model
divides a task into smaller ones (Map) and then combines
the obtained results (Reduce), to allow a powerful computing
(using parallelism) with a relatively low cost. The figure 6
illustrates the HDFS and MapReduce architecture.
Apache Spark [11] is another alternative to Hadoop which
uses in-memory primitives to perform faster distributed com-
puting. Spark loads data into memory and reuse it repeatedly to
overcome the problems presented by MapReduce in terms of
2017 6th IEEE International Conference on Advanced Logistics and Transport (ICALT)
114
iterative and online processing [12]. Many other open-source
platforms have lastly emerged as competitors to Apache Spark,
such as Apache Storm [13] and Apache Flink [14]. These real-
time processing platforms use pure streaming processing and
represent an alternative to the limitations of Spark from online
and streaming side [12].
Fig. 3. HDFS and MapReduce architecture [15]
B. Big Data Analytics
The data analytics concept combines different disciplines
and presents multiple analytical methods applied to explore
and investigate the data and extract the meaningful information
for new business values and decision support [16]. These
analytics are generally about extracting useful information
and new insights from the large collections of data, to give
decision makers effective operational reporting and dashboards
to monitor the performance, KPI, thresholds, etc. They also
use statistical and mathematical methods to describe and
understand data, validate hypotheses, simulate scenarios and
make predictive forecasts.
Fig. 4. Data Mining tasks
As a key concept in Big Data Analytics, the Data Mining
consists in applying statistical methods and data science tech-
niques to explore and analyse a large collection of data with
the purpose of finding useful and meaningful patterns. It uses
sophisticated algorithms and statistical models (e.g. Machine
Learning algorithms) to perform three kinds of analytics:
Predictive analytics,Descriptive analytics and Prescriptive
analytics.
The descriptive analytics transforms the data into mean-
ingful information for monitoring, visualization and reporting
purposes (e.g. clustering, association rules, etc), while the
predictive analytics makes prediction about the future for
decision support (e.g. regression, time-series analysis, etc).
As for the prescriptive analytics, they include predictive and
descriptive analytics to suggest decision options for real-
time process optimization [17]. Examples of predictive and
descriptive analytics models and algorithms are given in the
figure 4.

TRA NS PO RT AN D LOG IS TI CS
Supply chain management, reverse logistics, express de-
livery, freight logistics, e-commerce, air, maritime and land
logistics, are all types of logistics operations that were totally
transformed and significantly improved by the adoption of
new information and communication technologies in transport
chains. The digital transformation triggered by these tech-
nologies is creating growing sets of large-scale data. The
Internet of Things (IoT), as a key trend in logistics and
transport industry, deploys recent communication technologies
such as the Machine to Machine Comunication (M2M) to
virtually connect objects to the internet [18]. In fact, IoT
can be deployed for car-to-car communication and various
Intelligent Transportation Systems (ITS), especially with the
proliferation of use of sensors, Radio-Frequency Identification
(RFID), Global Positioning Systems (GPS) and WIFI, which
gives objects and vehicles more and more connectivity, and
hence transform the logistics and transport activities into an
important source of Big Data.
Fig. 5. Using Tri-axial accelerometer data to determine travel modes [19]
The collected data may generally be either born analogue
data or born digital data [20]. Digital data are those created
by a computing device to be specifically used in a machine
processing environment. In the transport and logistics context,
they may include data produced by vehicles, devices and
networked objects, GPS or other spatial data stamps, public
transport cards, portal access or RFID tags data, mobile
2017 6th IEEE International Conference on Advanced Logistics and Transport (ICALT)
115
devices connected to various kinds of networks (e.g. Wi-
fi,GSM), process logs and time stamps, SMS, Emails, etc.
For digital data sources, only specific data are produced and
retained to address some specific needs, in order to avoid
inflating storage and processing costs and capacity [19].
On the other hand, born analogue data come originally
from imprints of some physical phenomenon such as sound,
light, or presence of particular chemical compound, acquired
by a specific sensor and converted into a digital signal.
Sensing devices may include microphones, cameras, thermal
sensors, accelerometers, etc. These born analogue data can
be video streams from in-vehicle, surveillance or roadside
cameras (e.g. CCTV cameras for road traffic monitoring),
motion (accelerometers data), audio records of voice phone
calls, infrared radiation, light or electromagnetic reflectance
of objects, air pressure, temperature, etc [19].
Fig. 6. Interface of OpenStreetMap [21]
The gathered data in transport and logistics context are
generally sourced based on one of the three main sensing
modalities : purposely sensing, opportunistic sensing and
crowd sensing [19]. As for the opportunistic sensing, data
collected for one specific purpose and can be used for another.
Based on this approach, mobility can for example be better
understood by simply leveraging data arising from mobile
phones or credit card companies records [22]. The recent
transition in processing power and reporting frequency of
existing networks, as well as the increasing use of smart
phones with GPS capability has furthered the potential of
opportunistic sensing in gathering mobility data. The example
in figure 5 shows the possibility of determining the transport
mode by using data from an accelerometer-equiped phone de-
vice. In contrast of this modality, purposely-sensing modality
acquire data sets from ad-hoc sensor networks pre-configured
to study and analyse a specific object or phenomenon. With
the advances in computation and microelectronics, the use of
such sensors and their proliferation is often referred to a new
concept termed ”Smart Dust”. In this case, the gathered data
sets are usually more uniform and better aligned to process
and analyze for information and new insights extraction.
However, collecting real-time travel conditions or traffic
information (weather, traffic incidents, etc) in the purposely-
sensing modality, by using vehicle mounted sensing devices
(Vehicle to Vehicle communication - V2V and Vehicle to
Infrastructure communication - V2I), is still impractical in
many cases, for reliability and cots issues [23]. Instead, the
wide spread of use of smart phones and communication
devices has introduced the crowdsensing as an alternative in
which large-scale people can participate in the collection and
analysis of transport data. As an example, travel time and real-
time traffic flow information are usually inferred using crowd
sensing from taxis equipped with GPS devices [24]. Another
famous example is the OpenStreetMap [21] project which aims
at collaboratively create a free and editable map of the world
(see figure 6).
From a technical perspective, all these voluminous and
heterogeneous data might be seen as real problem and a
forbidding challenge in terms of storage, management and
processing. Yet, a huge opportunity in enhancing the quality of
processes and improving the operational efficiency of logistics
and transport services can also be gained from the untapped
potential of these Big sets of data.
IV. IMP ROV IN G OPE RATI ONA L EFFIC IE NC Y OF
TRA NS PO RT AN D LOG IS TI CS
One of the most challenging purposes of adopting Big Data
in logistics and transportation is to improve the operational
efficiency, by providing better decision making in terms of
operational and strategic resource planning, and improving
performance and process quality. In fact, operational efficiency
is primarily about providing high quality services in the
most cost-effective manner. Thus, taking advantages of the
capabilities of Big Data technologies to optimize the utilization
of resources and reduce operational costs, can be an important
advantage for any logistics providers [25].
A. Last-mile delivery
A relevant use case in which Big Data can significantly
improve the operational efficiency is the last-mile optimization
[1]. Traditionally, the last-mile delivery is known to be the
most complicated and the most expensive part of the delivery
process. In fact, transit points and transport routes used to be
coordinated and planned based on inconsistent information and
resources such as historical averages or even personal expe-
rience. Yet, Big Data analytics makes it possible to optimize
the matching between demand and available resources, and
perform real-time optimization of delivery routes to transform
the delivery network into a self-organizing infrastructure.
Yamato, the largest Japanese door-to-door delivery service
used to rely on the know-how of its sales drivers and their
personal experience to plan the delivery route on a daily basis.
Although this strategy allowed the company to build over
years a high-density delivery network in Japan, which could
be compared to an infrastructure like electric power or water
supply, it unfortunately can’t enable its replication in another
country. Therefore, Yamato started to collect Big Data of its
sales drivers to extract all the knowledge they acquired over
many years (the delivery route order, the map of the city and
2017 6th IEEE International Conference on Advanced Logistics and Transport (ICALT)
116
its fastest routes, and recipients schedules) and replicate it in
a new delivery infrastructure [26].
Fig. 7. GUI of Routific : a last-mile delivery optimization tool [27]
Another challenging issue in the last-mile delivery optimiza-
tion is the delivery route monitoring and optimization. In fact,
by tracking and monitoring the freight vehicles and shipment
items, the delivery routes can be analysed and automatically
changed according to new real-time information on traffic
conditions, weather, or any other incidents. This automated
control of large fleets of moving delivery resources can be ef-
fectively carried out using the real-time processing capabilities
of Big Data technologies [1]. The graphical user interface of
a commercial route optimization software is exposed in figure
7. This tool named Routific [27] allows the tracking of freight
vehicles fleet for a last mile delivery optimization.
B. Route Optimization
Big Data descriptive and predictive capabilities can also
provide all the needed information to perform optimization
tasks, resource planning and determine an optimal path re-
garding certain parameters and a certain cost. For instance,
by gathering and analysing large sets of traffic data, traffic
flow can be predicted and a real-time route optimization can
be performed by detecting traffic congestion on roads and
suggesting the best options for each case [28]. Lv et al. [29]
proposed a deep-learning traffic flow prediction approach by
training a deep neural network using a two months traffic flow
data collected each 30 seconds from 15000 detectors deployed
in freeway systems accross California. The traffic flow moni-
toring and congestion prediction is a key requirement in many
route optimization applications.
Besides the extraction of insights on travel, road and traf-
fic conditions, new optimization methodologies and efficient
routing approaches can be implemented via Big Data analysis
of the large-scale collected data. As an example, the huge
aviation data can be harvested to efficiently decide the routes
and manage the freights and passengers, in order to allow
effective flight plans and reduce route distance, fuel costs
and lost revenues from payload that could not be carried.
Kasturi et al. [30] used large scale aviation data to propose
an airline route profitability optimization model based on
Big Data analytics under multiple meta-heuristic methods.
Ning et al. [31] proposed a real-time dynamic medical rescue
vehicles scheduling and optimization to reduce running time
and improve punctuality, by using genetic algorithms and Big
Data technologies. Optimal route discovery and shortest path
problems can likewise be solved by analyzing Big Data (e.g.
Big trajectory data) and using data-driven approaches [32]
[33].
C. Crowdsourcing and Social Transportation
Crowdsourcing is a novel mean of solving problems through
contributions of a large online communities. In transport
and logistics applications, crowdsourcing approaches use the
collective wisdom to make easier the real-time collection and
update of data, allowing thus the design of more efficient
transportation systems. For instance, the GPS-based geograph-
ical navigation application Waze uses shared or user-generated
information to provide traffic monitoring and real-time route
guide [34] (see figure 8). Uber [35], the transportation and
delivery service is another relevant example of crowdsourcing
location-based applications, that uses shared location data and
transportation information.
Furthermore, the increasing use of smart phones and com-
munication devices, ubiquitous social networking websites and
apps such as Tweeter or Facebook, are becoming a space
in which people can provide a live description of the traffic
situation and instantly report any new incidents (traffic acci-
dent, traffic jams). By applying several analytics techniques
such as text analytics, natural language processing and pattern
recognition, traffic state information can be collected in real-
time [36][37].
Fig. 8. GUI of Waze : a real-time route guide [34]
Traffic forecasting and traffic monitoring using social sig-
nals from social media, wearable devices and mobile phones,
represents a typical example of application in the emerging
Social Transportation research field. By including dynamics
of social behaviour, cultures and organizations, Big Data and
social transportation can build a world of connected people,
vehicles, infrastructures and services to enter a new era of
Intelligent Transportation Systems [23]. By analysing the large
2017 6th IEEE International Conference on Advanced Logistics and Transport (ICALT)
117
sets of collected social signals data such as travel behaviour
or chosen trajectories, Song et al. [38] demonstrated that
the human mobility can be highly predicted. Consequently,
many new insights can be inferred such as the estimation of
travel time, the prediction of traffic flow, and the detection
of congestions in roads, which allows a more efficient traffic-
aware travel planning and routing optimization [39].
D. Smart Logistics
Adopting Big Data technologies to improve the operational
efficiency of transport and logistics is still a new trend.
However, the new advances in Data Science, Information
Technologies, Artificial Intelligence and Robotics, are leading
to the rapid emergence of many new scientific and techno-
logical concepts. The fourth industrial revolution also termed
Industry 4.0, aims at fully integrating the Internet of Things,
Artificial Intelligence, and Information Technologies in manu-
facturing, leading thus to the emergence of many new innova-
tive concepts such as Smart Technologies (cyber-physical and
computer-assisted systems with the ability of automatically
control entire work processes) and Smart Factory (self-learning
and self-regulating processes) [40].
These new capabilities of autonomous process and opera-
tion management are leading to the implementation of fully
autonomous decision processes in the transport and logistics
area, also known as Smart Logistics. The introduction of
self-driving and intelligent vehicles in a Big Data and IoT-
based infrastructure [41] is one of the key trends in Smart
Logistics, and can enable fully automated and more flexible
logistics solutions. As an example of futurist autonomous
vehicles, the ”Future Truck 2025” [42] is a prototype of a
self-driving truck designed by Mercedes for freight transport.
Amazon is also exploring an alternative for home-delivery
service using autonomous drones, which will be able to track
customer location using his phone GPS and deliver the parcel
within 30 minutes [26]. In this context, Big Data technologies
represent a key asset in improving the operational efficiency of
transport and logistics, since the more extensively information
on traffic, weather, or vehicles sensors data are available, the
more efficiently the logistics and transport flows can be self-
managed and optimized.
E. Anticipatory Logistics
The Anticipatory Logistics concept relies on Big Data
predictive analytics to anticipate demand before requests and
orders are placed, which boosts the service quality and process
efficiency and leads to shorter delivery times. The Smart City
Planning uses anticipatory algorithms with the purpose of
matching logistics resources with demand. In this context,
Anticipatory Shipping enable a same-day or even a one-hour
delivery services, by anticipating the customer demand and
moving goods to distribution points and centers closer to zones
where potential customers were detected based on the analysis
of their purchasing behaviour.
A pertinent example of anticipatory shipping was imple-
mented by Amazon, who patented in 2013 an effective method
for a anticipatory package shipping system [43] (see figure 9).
However, there are still many challenges in integrating these
prediction-based anticipatory shipping systems with traditional
order-based delivery methods.
Fig. 9. Anticipatory Shipping method developed by Amazon [43]
Anticipatory Logistics also involves the concept of pre-
dictive maintenance, which consists in predicting the main-
tenance needs of a machine right before the failure occurs.
By analysing the data collected from real-time monitoring
of machines or vehicles, predictive maintenance systems can
detect the faults and predict the maintenance requirements
early, reducing hence the downtime costs for both logis-
tics service providers and the customers [44]. For instance,
Siemens is heading to innovative and next-generation pre-
dictive maintenance services, by introducing the concept of
Internet of Trains, which consists in enabling new data-driven
methodologies for predictive maintenance of trains fleet [45].

The large-scale multi-modal data collected in transport and
logistics applications are leading to numerous challenges to
raise in terms of processing capabilities, computer architecture,
and in data science and analytics. The incompleteness, the
inconsistency and the heterogeneity of these sensed data re-
quire a new set of methodologies and analysis algorithms to be
explored and further enhanced. The Big Data streams sourced
from sensors and devices used in logistics and transportation
systems are one of the key areas of data mining applications.
Consequently, new perspectives are opened for exploring novel
approaches of Big Data a such as the Streaming Analytics
[46][44] which deals with the analysis of data-in-motion, and
the IoT Big Data Stream Mining [47] to derive insights from
the internet of things data.
Data fusion methodologies are also widely used in trans-
port and logistics applications to improve the descriptive and
predictive analytical capabilities of the implemented systems.
However, data fusion is still in its preliminary stage of
engineering and scientific fields especially in logistics and
2017 6th IEEE International Conference on Advanced Logistics and Transport (ICALT)
118
transportation area, and requires new systematic methodolo-
gies on data analysis and organization [23]. Furthermore, the
Big Data predictive analytics have also their own limitations.
In fact, predictive models based on data fitting are not able
to resolve all the issues and provide accurate predictions,
since history cannot always predict the future. Thus existing
predictive models are still not able to offer reliable anticipatory
or fully self-regulating or self-learning processes.
Besides, the security and privacy issues represent a serious
challenge for the transmission and storage of the large-scale
sourced transport data. The generated new knowledge from
the fusion of the opportunistically sensed and crowd-sensed
data can actually open avenues for misuse, since it involves
information and insights derived from data without the consent
of their sources (people or organizations who are the object of
these data). In addition, the increasing abilities of these multi-
platform sensing technologies to precisely track and locate
people and vehicles without their permission, is creating new
challenges in terms of data anonymization, confidentiality and
policy [48].
VI. CO NC LU SI ON
This paper explored a review of Big Data technologies
and analysed the opportunities and benefits they provide to
transport and logistics in terms of operational efficiency. The
predictive and analytical capabilities of Big Data technologies
as well as the new insights and knowledge they can derive
from the huge amount of data collected along the logistics
and transport chains, offer valuable opportunities in terms of
operational efficiency. Last-mile delivery, route optimzation,
crowdsourcing and social transportation, Smart Logistics and
Anticipatory Logistics are the most likely to revolutionize
transport and logistics in the coming years. Yet, more efforts
still need to get involved into surpassing the scientific and
technical challenges and dealing with the policy and privacy
issues that transport and logistics Big Data are raising.
For future studies, it would be interesting to investigate new
data-driven approaches that use big data analytics (descriptive,
predictive and prescriptive analytics) to deal with the optimza-
tion problems encountered in the transport and logistics fields.
More specifically, smart logistics and self-driving vehicles
which are expected to increasingly become the norm, are
essentially based on fully autonomous decision processes that
need more advanced analytics models to solve in real time the
optimization problems. In this context, prescriptive analytics,
as an emerging and promising technology, can be further
investigated in order to propose new prescriptive analytic
optimization models for the decision support in transport and
logistics applications.

... This sophisticated coordination points to the pivotal role that logistics management, through the order fulfillment process, plays in ensuring omnichannel retailing supply chain effectiveness and efficiency (Devari et al., 2017;Dohrmann et al., 2022). Notably, the coordination of the order processing, storage, and movement of physical products within and between channels in omnichannel retailing is facilitated by technologyenabled order fulfillment (Alicke et al., 2016;Borgi et al., 2017;Dohrmann et al., 2022). These enabling technologies simultaneously provide value while engendering potential information privacy issues. ...
... The advent of digitization across the supply chain has led to the availability of large-scale data sets with information on numerous dimensions of supply chain operations. These data sets can comprise information on purchase transactions, contract terms and conditions, traffic volumes, customer and facility addresses and locations, and competitor pricing for instance (Borgi et al., 2017;DHL, 2023). In retail, technology and the data management associated with its use can support order fulfillment activities in any of three ways (Dohrmann et al., 2022;LaBombard et al., 2019). ...

Retail order fulfillment is a major supply chain management process. The process is complex to manage because of increases in e-commerce activity, which compels retailers to respond by developing omnichannel retailing strategies to serve both online and in-store retail in an integrated manner. Retailers and the logistics service providers that serve them must effectively manage this increased complexity to gain a competitive advantage in retail markets. Market leaders have done so by leveraging advanced technologies and data analytics in the order fulfillment operations of their supply chains. The adoption of these technologies has led to both an increase in customer service levels and operating efficiency gains for retailers. Because of their data gathering and dissemination capabilities, however, the implementation of these technologies has conjured concern amongst retail fulfillment operations employees and retail customers alike. Given this reality, we organized this chapter around three objectives. First, we provide an overview of supply chain management, and the logistics management and order fulfillment processes within it. Second, we detail why retail fulfillment operations represent a context replete with potential privacy-related issues resulting from the pervasive use of highly advanced technologies capable of collecting data on both human subjects and operational processes. Third, we discuss two highly salient forms of privacy in retail fulfillment operations, workplace privacy and information privacy, from the perspective of two stakeholder groups, employees and customers. We identify and survey the concepts, factors, and variables drawn from extant research that explain, describe, and challenge aspects of both employee and customer privacy concerns during order fulfillment operations in omnichannel retailing.

Road transport accounted for 20% of global total greenhouse gas emissions in 2020, of which 30% come from road freight transport (RFT). Modeling the modern challenges in RFT requires the integration of different freight modeling improvements in, e.g., traffic, demand, and energy modeling. Recent developments in 'Big Data' (i.e., vast quantities of structured and unstructured data) can provide useful information such as individual behaviors and activities in addition to aggregated patterns using conventional datasets. This paper summarizes the state of the art in analyzing Big Data sources concerning RFT by identifying key challenges and the current knowledge gaps. Various challenges, including organizational, privacy, technical expertise, and legal challenges, hinder the access and utilization of Big Data for RFT applications. We note that the environment for sharing data is still in its infancy. Improving access and use of Big Data will require political support to ensure all involved parties that their data will be safe and contribute positively toward a common goal, such as a more sustainable economy. We identify promising areas for future opportunities and research, including data collection and preparation, data analytics and utilization, and applications to support decision-making.

In the realm of logistics and transportation, the efficiency and reliability of express air cargo services are critical factors influencing global trade and supply chain management. This study investigates the application of machine learning (ML) techniques to optimize operations in express air cargo services, aiming to enhance service efficiency, reduce costs, and improve customer satisfaction. The research focuses on a dataset sourced from a leading international logistics provider, encompassing a diverse range of variables such as flight schedules, cargo volumes, weather conditions, and operational constraints. Through the implementation of ML algorithms, including supervised learning for demand forecasting and reinforcement learning for route optimization, the study explores how AI-driven decision-making can streamline cargo handling processes and mitigate operational challenges. Key ML methodologies employed include deep neural networks for predictive analytics, clustering algorithms for segmentation of cargo types, and reinforcement learning algorithms like Q-learning to dynamically optimize route planning and resource allocation. These approaches are designed to adapt to real-time data streams and operational constraints, ensuring agility and responsiveness in managing complex logistics scenarios. The findings reveal significant improvements in operational efficiency and cost-effectiveness, with ML models accurately predicting demand fluctuations and optimizing routing decisions to minimize transit times and maximize resource utilization. Moreover, the integration of explainable AI techniques enhances transparency and trust in automated decision-making processes, crucial for stakeholders in navigating regulatory compliance and customer expectations.

The precession of a ferromagnet leads to the injection of spin current and heat into an adjacent non-magnetic material. Besides, spin-orbit entanglement causes an additional charge current injection. Such a device has been recently proposed where a quantum-spin hall insulator (QSHI) in proximity to a ferromagnetic insulator (FI) and superconductor (SC) leads to the pumping of charge, spin, and heat. Here we build a circuit-compatible Verilog-A-based compact model for the QSHI-FI-SC device capable of generating two topologically robust modes enabling the device operation. Our model also captures the dependence on the ferromagnetic precision, drain voltage, and temperature with an excellent (> 99%) accuracy.

Spiking neural network offers the most bio-realistic approach to mimic the parallelism and compactness of the human brain. A spiking neuron is the central component of an SNN which generates information-encoded spikes. We present a comprehensive design space analysis of the superconducting memristor (SM)-based electrically reconfigurable cryogenic neuron. A superconducting nanowire (SNW) connected in parallel with an SM function as a dual-frequency oscillator and two of these oscillators can be coupled to design a dynamically tunable spiking neuron. The same neuron topology was previously proposed where a fixed resistance was used in parallel with the SNW. Replacing the fixed resistance with the SM provides an additional tuning knob with four distinct combinations of SM resistances, which improves the reconfigurability by up to ∼70%. Utilizing an external bias current ( I<sub>bias</sub> ), the spike frequency can be modulated up to ∼3.5 times. Two distinct spike amplitudes (∼1V and ∼1.8 V) are also achieved. Here, we perform a systematic sensitivity analysis and show that the reconfigurability can be further tuned by choosing a higher input current strength. By performing a 500-point Monte Carlo variation analysis, we find that the spike amplitude is more variation robust than spike frequency and the variation robustness can be further improved by choosing a higher I<sub>bias</sub> . Our study provides valuable insights for further exploration of materials and circuit level modification of the neuron that will be useful for system-level incorporation of the neuron circuit.

The rapid increase in data generation with technological developments and scientific research has led to the development of new data analysis tools, including Machine Learning (ML). ML is an alternative to conventional engineering methods and it does not require field knowledge of the problem to obtain solutions. However, ML algorithms can be complex, and expert knowledge is required to use them effectively. Various methods have emerged to answer this problem. There are many areas and problems where machine learning can be applied. We have limited our research to the problems that can be solved by Computer Vision and AutoML. We use the AutoML and Vision based approach to achieve a solution for Classification, Object Detection and Segmentation tasks. Our aim was the develop a platform that works without expert intervention. Users loads the dataset and choose the tasks that they want and without touching anything they can train their model. When trainning has done, they can stream it in real time with their own hardware.

Logistics plays a significant role in the economy with its main contribution to the gross domestic product (GDP) of many countries. In highly developed countries, logistics costs compared to their GDP range between 8 and 10%. As globalization of trade develops, the importance of improving logistics’ active efficiency is essential for any business enterprise to gain a competitive advantage. Many scholars have so far made great efforts to study logistics functionality, and a large number of relative literature on basic logistics activities of transportation, warehousing, and inventory have been published. Unfortunately, past studies on logistics operational activities are mostly categorized as single research themes of basic logistics activities. Few studies comprehensively considered basic and value-adding activities with entire logistics operational activities. Therefore, for typical multi-criterion decision-making (MCDM), the F-DEMATEL technique is adopted for evaluating the crucial performance indicators of time, cost, quality, service, and innovation to improve the reliability of expert evaluations under uncertain environments in this study. Also, the F-TOPSIS technology is used to calculate all alternatives to help decision-makers develop appropriate operational activities of logistics management. The study result identifies 13 important operational activities of logistics functionality. Besides, the data from a case study of the elite interview is used for validation. The F-DEMATEL is used to obtain the weights of the core criteria. The importance of critical weighted indicators from the F-DEMATEL calculation show “Service” > “Cost” > “Quality” > “Time” > “Innovation”. In addition, the F-TOPSIS is used to prioritize critical activities in logistics functionality. The ranking of the critical basic activities demonstrates that “Transportation/ Distribution” is the most critical logistic activity, followed by “Information” and “Pick and Pack”. Also, the ranking result of the critical value-adding activities shows that “Consignment Stock” is the most critical value-adding activity, followed by “Returns and Quality Control” and “Repair and Maintenance”. Therefore, the logistics managers give priority to the formulation of improvement management based on these ranks. The proposed suggestions of evaluating methods of F-DEMATEL and F-TOPSIS, important 13 crucial activities of logistics, evaluating indicators of logistics activity, and ranks of crucial activities in logistics functionality, thus, make up for a deficiency in previous research that lacks an empirical analysis of the crucial operational activities in logistics functionality.

As a versatile energy carrier, hydrogen possesses tremendous potential to reduce greenhouse emissions and promote energy transition. Global interest in producing hydrogen from renewable energy sources and transporting, storing, and utilizing hydrogen is rising rapidly. However, the high costs of producing clean hydrogen and the uncertain application scenarios for hydrogen energy result in its relatively limited utilization worldwide. It is necessary to find new promising technological paths to drive the development of hydrogen energy. As part of technological innovation, emerging technologies have vital features such as prominent impact, novelty, relatively fast growth, etc. Identifying emerging hydrogen-energy-related technologies is important for discovering innovation opportunities during the energy transition. Existing research lacks analysis of the characteristics of emerging technologies. Thus, this paper proposes a method combining the latent Dirichlet allocation topic model and hydrogen-energy expert group decision-making. This is used to identify emerging hydrogen-related technology regarding two features of emerging technologies, novelty and prominent impact. After data processing, topic modeling, and analysis, the patent dataset was divided into twenty topics. Six emerging topics possess novelty and prominent impact among twenty topics. The results show that the current hotspots aim to promote the application of hydrogen energy by improving the performance of production catalysts, overcoming the wide power fluctuations and large-scale instability of renewable energy power generation, and developing advanced hydrogen safety technologies. This method efficiently identifies emerging technologies from patents and studies their development trends. It fills a gap in the research on emerging technologies in hydrogen-related energy. Research achievements could support the selection of technology pathways during the low-carbon energy transition.

The challenge of deriving insights from the Internet of Things (IoT) has been recognized as one of the most exciting and key opportunities for both academia and industry. Advanced analysis of big data streams from sensors and devices is bound to become a key area of data mining research as the number of applications requiring such processing increases. Dealing with the evolution over time of such data streams, i.e., with concepts that drift or change completely, is one of the core issues in IoT stream mining. This tutorial is a gentle introduction to mining IoT big data streams. The first part introduces data stream learners for classification, regression, clustering, and frequent pattern mining. The second part deals with scalability issues inherent in IoT applications, and discusses how to mine data streams on distributed engines such as Spark, Flink, Storm, and Samza.

All metropolitan cities face traffic congestion problems especially in the downtown areas. Normal cities can be transformed into “smart cities” by exploiting the information and communication technologies (ICT). The paradigm of Internet of Thing (IoT) can play an important role in realization of smart cities. This paper proposes an IoT based traffic management solutions for smart cities where traffic flow can be dynamically controlled by onsite traffic officers through their smart phones or can be centrally monitored or controlled through Internet. We have used the example of the holy city of Makkah Saudi Arabia, where the traffic behavior changes dynamically due to the continuous visitation of the pilgrims throughout the year. Therefore, Makkah city requires special traffic controlling algorithms other than the prevailing traffic control systems. However the scheme proposed is general and can be used in any Metropolitan city without the loss of generality.

Objectives: Intelligent Transportation System (ITS) is raising the interests of the research community in the field of communication. The main objectives of this work are to implement ITS scenario and evaluate the Traffic Density Estimation for different cities for checking the density of vehicles on the different roads and perform a comparative evaluation of traffic densities in the different number of city based scenarios and to increase the accuracy of the density prediction technique for ITS. Method/Statistical Analysis: In this manner, an advanced density prediction technique has been proposed for the prediction of density on the road. The proposed technique is based on the number of vehicles on the road, in which vehicle on the map of the three cities at a particular instance of time has been estimated. After estimating the density of vehicle, prediction of that density has been done which shows that there is a maximum density on the lane and in future density on the road has been predicted. Finding: A range of values has been generated with the help of a dedicated simulation scenario using SUMO simulator. The computed values have been used for estimating the density of vehicles in Chandigarh, Delhi and Kolkata based on road side scenarios using Poisson distribution for randomly generated of vehicles and the obtained values has been evaluated to compare the densities of vehicles for these three cities. Improvement: When we are talking about traffic, then the term comes in our mind is congestion. To avoid that congestion on the roads, we use the Poisson distribution in which vehicle generates after every instance of time. With the help of this distribution, the amount of congestion on the roads can be decreased and this technique is very effective on the hurdle like jam.

In China, traffic police's micro-bo provides instant information for travelers and can help drivers to avoid congested roads. Management rules and laws help to maintain the road traffic order, improve traffic flow, and prevent traffic accidents. How to build reasonable rules and laws is very important. The analysis of traffic flow is good for building traffic laws and rules. In this paper, the congestion time, congested place, and congestion reason are analyzed on the traffic police's micro-bo, and the theories of linguistic dynamic systems based on multifactor time-varying universe and fuzzy comprehension evaluation are used to analyze traffic flow and dynamic fuzzy rules on time-varying universe are built to provide the corresponding traffic management rules. As an example, Shenzhen's traffic police micro-bo is used to study the information of traffic congestion, including jam session, congestion location and reasons, and disposal methods, and their results are presented in language form, i.e., keywords walls; then, the traffic flow of Labor Day is discussed.
