1. Introduction
Globalization has made supply chain management and development of robust supply chains
crucial in almost every industry and business. SCM deals with the entire chain of process involved
in any activity, production or business. In the current wake of industry 4.0 and ever-increasing
globalization, competition has witnessed a surge in the business market. Due to this companies
are expanding their operations with the help of more robust supply networks. E-commerce
websites are a great example of how supply chain networking and management is changing the
scenario people lead their lives. A good supply chain significantly improves the efficiency and
competitiveness of an organization. SCM will incorporate largely all the aspects of operations,
supply and demand planning, administering, control of processes etc. Supply chains are also
prevalent in various industries that deal with management of flow of perishable products or
commodities having a limited shelf life such as agriculture and food industry.
Traditionally, barcodes have been popularly used in supply chains. These barcodes required a
physical contact, clear line of sight to be read or detected. Due to increasing competitiveness
around the world, everyone is trying to cut down on cost and time involved in the entire supply
chain. RFID has emerged as an alternative to barcodes and a great solution to reduce overall time
and cost involved in supply chains. RFID is basically a wireless technology that, as the name
suggests, transmits information through radio waves. RFID stands for ‘Radio Frequency
Identification.’ These RFID systems have great advantages over traditional barcode systems such
as it does not require a physical connection or line of sight.
RFID is a relatively new concept introduced into SCM in the past decades. However, RFID as
a technology has been prevalent since World War II, back then it was primarily used for basic
identification applications [1]. In supply chains RFID can play a major role in identification,
inventory management, manufacturing, shipping and distribution, managing operations etc. A
great rise in deployment of RFID systems can be witnessed in SCM which can be attributed to its
many advantages when compared to conventional systems.
This paper is focused on detailed literature review concerning the deployment of RFID systems
into supply chains and SCM. The paper studies the RFID technology in required detail and
provides a summary regarding the technology, its components and classifications. Further on, the
paper focuses on reviewing the various application RFID systems have been deployed in SCM. It
also provides a merit-demerit analysis of the technology. The main aim of the paper is to provide
a holistic review of the RFID systems and its deployment in SCM.
2. RFID systems
RFID technology has been around for a long time now. However, it has gained recent attention
in the past few decades for various applications in a variety of sectors, especially sectors such as
supply chain management that are subjected to harsh environments and often deal with products
which are perishable in nature. RFID systems are often compared and denoted superior to the
conventional barcode systems. RFID has various advantages over barcodes such as it does require
a line of sight of physical connection, it has better range etc. Most importantly barcode systems
are ineffective in functioning in harsh environments which are subjected to dirt, hazardous
contamination, low or high temperatures etc. [1]. RFID systems do share similarities to its
competitor technology, which is barcodes. Bothe these technologies rely on scanning, reading
information and then relating the information to the stored data. However, there are major
differences which come across as RFID being advantageous over barcodes. Firstly, no line of sight
is needed in case of RFID which makes the entire process very fast and less prone to human errors.
In the barcode system, workers will have to manually scan each of the barcodes but with RFID
scanning can be done in bulk instantaneously enabling multiple parallel reading. RFID is also
capable of manipulating data without a need to alter the database corresponding to the tag [3].
RFID sensors have 3 main components that govern the entire functioning. These are tags,

reader and software. A tag is essentially a memory storage device. Tag consists of small chips
which store data and are embedded with an antenna, which is used for transmitting signals between
tag and reader. A reader is nothing but a decoder which reads the data stored in the tags. The
communication between tag and reader is established via radio waves. Readers have an
appreciable range of centimeters to meters. The range also depends upon the type of tag and
operating frequency. All this data collected is then processed using a software/computer similar
to barcode systems [1].
RFID tags can be classified based on operating frequency range and based on the activity. Tags
can be classified as active, passive and semi-passive. Passive tags are more popular in terms of
applications and deployment and less costly as compared to active tags. The difference between
the two is that active tags have a battery embedded and they remain active throughout their own
power-supply. On the contrary, passive tags do not have any battery and they are activated by the
trigger received from readers [1]. RFID tags operate in different frequency ranges namely, low
frequency, high frequency, ultra-high frequency and microwave range. The classification based
on operating frequencies is shown in Fig. 1. These ranges are to be selected based on a particular
application. In applications involving SCM, usually tags operating in high and ultra-high
frequency are used [3].

3. Applications in SCM
RFID systems can be effectively deployed for various applications such as retail, warehousing,
asset tracking, assembly, configuration manufacturing, logistics, transportation etc. In nutshell,
RFID systems can be used at various phases in different supply chains. Table 1 presents a detailed
literature review of applications of RFID sensors in supply chains.

business-to-business logistics, internal operations, business-
to-consumer marketing, and after-sales service applications.
As industry adoption of RFID increases there is an emerging
interest by academic researchers to engage in scholarly
investigation to understand how RFID relates to mobility,
organizational and systems technologies (MOST)

4. Critical analysis of deployment of RFID in Supply Chains
When compared to conventional barcode systems, RFID technology proves to be far more
promising in terms of what it has to offer. RFID tags are capable of continuously collecting data
when products transit from shelves to checkout. Thus, this technology helps in minimizing labor,
its associated costs and practices such as shoplifting. The tags have significantly helped in
reordering, stocking, and keeping track of purchases. Smart-shelves are introduced in the retail
sector which are based on RFID systems which prevent situations such as out-of-stock.
RFID systems are also prevalent in shipping and distribution applications. Traceability is
improved using RFID as it enables tracking of the pallets and allows real time decision
implementation. A fleet of 2600 trucks equipped with RFID tags at a particular logistics provider
company enables automatic monitoring of docking and undocking activities.
Supply chain activities such as manufacturing and assembly lines are also potential areas of
RFID deployment. Identification of products can be done using these systems. RFID ensures the
entire quality of process by providing real time checks during assembly. It also promotes lesser
labor and thus optimizes the process cost-wise. A great example of this is the case of Ford Motors
DEPLOYMENT OF RFID SENSORS IN SUPPLY CHAIN MANAGEMENT A REVIEW.

that have been using RFID tags. An RFID tag is attached to each car’s chassis skid. This tag is
instrumental in indicating which parts and components are to be installed on the chassis,
communicating via the serial number to the reader. As the chassis transits from one assembly
station to the following one, readers read the chassis’ assembly needs automatically so that the
appropriate components can be installed thus eliminating error prone manual barcode scanning
[3]. Intelligent components in ETO management have also been studied. RFID technology is
capable of identifying, tracing location and establishing communication. RFID sensors operating
in the UHF range are proven to be capable of creating intelligent components [59].
RFID systems have proved to optimize logistics, warehousing and transportation activities.
Conventionally, all these activities involved a certain amount of time in inspection, identification
and documentation which was carried out by human force. All this causes a hindrance into the
flow of goods and services in terms of time. RFID can greatly eliminate these hindrances by
automating the entire manual process involved. It provides benefits such as reduced time and labor
involvement and increased visibility. Thus, goods and services move faster through the SC’s and
at a comparatively lower cost. RFID also works efficiently in inventory management by improving
the inventory accuracy, which is the difference between physical inventory and logical inventory.
In the most ideal case, both these inventories are equal. However, due to a series of reasons such
as loss of goods, errors in input etc. both the inventories could differ. Logical inventory is basically
recorded in computers using ERP, WMS etc. RFID can automate the entire scanning process and
thus improve the records [3]. Throughout the supply chain, RFID can be incorporated at various
checkpoints for a plethora of service exchange. RFID will not only ensure identification,
monitoring and tracking but also aid manufacturing, warehousing and inventory, retail, logistics
and distribution, as shown in Fig. 2. Basically, RFID can be said to be a very versatile technology
that will continue to function effectively throughout the supply chain right from inbound material
to delivery.
Fig. 2. Various RFID transactions during a Supply Chain [60]
RFID sensors are enabled with GPS sensors in order to perform the tasks of tracing, tracking
and identification. Another important inclusion is the temperature and environment sensors which
enable them to be deployed effectively in cold chain monitoring. Cold chain refers to the flow of
temperature sensitive and environment sensitive products. A certain temperature and
environmental conditions such as humidity, moisture etc. is to be maintained in order to ensure
their quality and shelf life is maintained. RFID enabled with temperature sensors can give real
time data of the environment and enable human operators to adjust it according to the changes.
These RFID sensors are installed in the boxes or pallets and are believed to improve the efficiency
of cold chains.
The applications of RFID in retail have been used to encourage intelligent business-to-business
e-commerce supply chain management with the aid of the EPC network [45]. The EPC network
is a unique feature and a standard for all RFID infrastructure composing essentially of several
DEPLOYMENT OF RFID SENSORS IN SUPPLY CHAIN MANAGEMENT A REVIEW.
VENKESH AGARWAL, SONALI ANKOLIKAR
12 JOURNAL OF MECHATRONICS AND ARTIFICIAL INTELLIGENCE IN ENGINEERING
components such as the EPC code, which when incorporated into the chip and attached to an item,
provides the details of it for e.g., Temperature, product size, expiry date, etc. The next component
is the RFID reader which identifies any EPC tag/ RFID chip and forwards the information to the
next component i.e., SAVANT. Analogous to the middleman in the entire operation, this
component communicates between the readers and the application systems. It can be further
modified to filter the data according to the specific needs of the organization with the help of the
EPC-IS i.e., the fourth component. It is an information service that provides a gateway between
any requester of information and the organization’s application systems and data. The last
component of the EPC network is the local Object Name Service which is an authoritative
directory of information sources available in order to clarify the details including the EPC tags
used in the supply chain. Therefore creating ‘smarter products that are able to interact with correct
stimuli is helping to enable and facilitate the smoother logging of data in registries within an
organization saving time and effort. With this, many large-scale retailers are investing more in
information management which has helped them to expand business within a shorter amount of
time. It has also enabled retail giants to cross-check their product qualities and customer service.
Considering the role of the deployment of RFIDs in Supply Chain management when it comes
to a buyer-seller relationship [57], it has generated an open network of the flow of information
and monitoring has been easier than ever. It has generated a healthy, competitive yet
knowledgeable environment where suppliers and buyers maintain their connections. Its integration
is more visible when we look at EPC global [46]. It is one of the two primary RFID standards. In
essence it is an internet-based supply chain model aimed at improving supply chain end to end
visibility. One of its key components is the EPC, which is discussed earlier as well. RFID
deployment in the supply chain management has been broadened in perspective with
authentication applications as well. Automatic data acquisition, location, identification etc. all are
products of RFID’s integration with the supply chain Deployment of RFID in supply chain
management provides greater power when it is combined with GPS and Bluetooth which help in
creating a closed loop in monitoring the products. RFIDs have the largest application in supply
chain management. One of the biggest problems a system faces is shrinkage [42]. Various factors
contribute to shrinkage and it is one of the main problems that have been reduced significantly.
Material handling requirements have reduced phenomenally due to the deployment of RFIDs and
respective supply chain networks generated with the help of RFID tags. The usage of these systems
has made is much easier to create accurate databases without much human intervention thereby
saving time and capital. Quicker exception management has enabled impressive applications,
especially in the health-care supply chain management system. Quality control and production
tracking, as explained earlier, are incredible feats achieved due to this system.
5. Advantages and limitations
RFID has its advantages and disadvantages as any modern technology does. As a technique
heavily dependent on the deployment of radiofrequency waves its accuracy is largely dependent
on the accuracy of the transmission and receiver devices involved in the entire process. The entire
process depends on the whether the tags used are active or passive. Advantages of using active
tags in cases of applications where regular data monitoring takes place can generate large amounts
of data and help improve the supply chain therefore fulfilling its purpose in its deployment in the
sector. They can be used and implemented over much larger distances/ ranges making them a lot
more efficient in terms of enabling distant communication between management systems in the
SCM chain. As compared to barcodes, RFID readers and tags do not need line of sight
communication and can be worked from fairly distant areas. Even though the distance will vary
according to the type and configuration of the readers and tags, it encourages the warehouses to
effectively save time. In comparison to other monitoring devices or tagging devices RFID can be
read and overwritten. They can be reused and are much durable thus removing the hassle of
replacement or loss related to monitoring in the SCM system much less. In a SCM the deployment

JOURNAL OF MECHATRONICS AND ARTIFICIAL INTELLIGENCE IN ENGINEERING 13
of safe and secure tagging methods is super important. Thus, RFIDs provide the service of an
encrypted service which remains secure throughout the life cycle of the chain. This makes it
difficult to easily replace a tag already registered into the system. Another advantage of the RFID’s
tags deployed is the fact that they are easily readable once in the system.
In essence, RFIDs have made it so much easier for an organization to manage the entire supply
chain management. It has reduced several instances of reduction of human errors due to its
automatic logging into the system and in turn increased the lifecycle of certain aspects of the
products. The introduction of RFIDs significantly improved the operations over various range of
bandwidths and not just over wavelengths.
In addition to simple active and passive RFIDs, the other types of RFIDs used are Near-field
and Far-field RFIDs. All of which make use of EM spectrum in addition to radiofrequencies.
Although we have seen considerable number of advantages, we do observe several limitations that
come along with its deployment in the SCM systems. Ideally any corporation aiming to set up its
RFID infrastructure will have to incur initial costs that tend to be large. The amount of money
required to set it up might not make the operations for the organization profitable. Even though
these systems once deployed are highly accurate they are prone to collision dude to usage of waves
for emission of signals. This could result in superposition and hence generate inaccurate readings.
The infrastructure of the system is also dependent on the frequency The systems across
organizations and countries vary as s result of lack of standardization. As mentioned in the
challenges of deployment of RFIDs in SCM systems, lack of standardization makes it much harder
for universal systems to be deployed and ever specification followed region-wise makes it much
more difficult to encourage uniformity across various outlets of the same organization. Although
these systems once deployed tend to be secure it does not mean they are completely fool proof
and free of risk. They can be hacked from the connected data base management systems from the
SQL serves to which they SCM system is connected to. Unauthorized devices which read
radiofrequencies may be able to hack or read into the system.
6. Challenges
One of the major difficulties faced by RFIDs and their deployment is that the effectiveness
will largely be dependent on the type of tag itself. Some tag can offer longer reading ranges but
fail to hold data for enough time whereas others can hold larger amounts of data and cost less.
RFID is still not feasible for businesses that are not financially, technically and operationally
sound [46]. The initial cost and maintenance of setting up a system for a business can create
generate complications. There is an upfront expense of RFID readers and tracking software as
well as the continuing cost of the different types of RFIDs.
RFID isn’t ideal for all situations. Especially when it comes to monitoring different types of
materials and substances. Liquids can absorb some of the radio signals and while others can
bounce off the material if it is a metal. There is a huge amount of scope for the improvement of
accuracy and precision in this technology when it comes to its deployment in the supply chain as
well. In the case of too many readers, there is a possibility of collisions and over-reading in the
line of monitoring. Moreover, there are a lot of costs involved when it comes to training and
implementation of the processes. It is also defined by the level of tagging involved. If the tagging
level is at an item level, the number of tags increases significantly, and hence cost of investment
increases. Pallet level tagging, although cheap, does not provide the benefits of large data storage.
Another concern is the lack of standardization. Many parameters when thoroughly considered do
not necessarily yield results due to a lack of standards and normalization. Data warehousing and
enterprise integration also play a crucial role in the cost of investment and integration of the RFIDs
in the supply chain of any business. In order to manage the vast amounts of data generated in a
single day, the organization must be prepared to handle it and be able to use it to its advantage
which is, obviously, a very time-consuming and costly process.
Considering the advantages of RFID systems in supply chains, new developments in the
DEPLOYMENT OF RFID SENSORS IN SUPPLY CHAIN MANAGEMENT A REVIEW.
VENKESH AGARWAL, SONALI ANKOLIKAR
14 JOURNAL OF MECHATRONICS AND ARTIFICIAL INTELLIGENCE IN ENGINEERING
technology to overcome these challenges is needed. With new developments, RFID technology
can monopolize all the supply chains and significantly improve the entire the market of supply
chain management. It will be advantageous for all the stakeholders and give the supply chains a
totally new dimension in terms of its operations and efficiency.
7. Conclusions
RFID sensors-based technology is transforming the supply chain industry for the better. RFID
comes along with various advantages such as providing real time data, tracking, identification,
tracing, automating manual processes etc. All these have proved to be of significant importance
in the supply chain industry. This paper has provided a thorough literature review of the
deployment of RFID in SCM and their performance. It categorizes various application areas of
RFID in SCM through Table 1. The paper also gives brief insights into the technology and it’s
functioning thus enabling a complete understanding of the technology and how it is being
deployed for various applications. Even though RFID has been there for decades, its popularity is
quite new in the field of SCM. It is transforming the entire SC with its capabilities due to embedded
GPS and Temperature monitoring systems. RFID systems are providing optimized results in time,
money and resources utilized as compared to conventional methods. The paper also draws
frequent comparison between RFID systems and the much prevalent conventionally used barcodes
systems and how RFID surpasses it. Thorough in-depth analysis of the deployment of RFID
sensors in supply chains have shown better productivity and improved efficiency of the supply
chain. RFID has great potential in this industry, it can revolutionize and transform every possible
supply chain. However, sufficient further development is needed in order to make it viable for all
kinds of supply chains. In challenges, we have seen how certain barriers with the technology is
limiting its application in certain cases. But with increased attention towards this advantageous
technology, better results can surely be expected. Changing the external design of the sensors and
tags to make it robust to handle different conditions is needed. At the same time, the loss in
transmission in some cases due to liquids can eliminated by providing alternative means of
installations and amplifiers. Even though a lot of applications have been actively found installed
with RFID, there is a certain scope of research and development. RFID has the potential to bring
in more sound changes in the SCM industry thus making the system even more advanced and
technologically equipped.

... Entende-se por inventário físico, a contagem de todos os itens existentes no estoque [4], realizando um levantamento de todos os materiais ali presentes naquele momento, tornando possível reconhecer possíveis diferenças de estoque. Existem diferentes maneiras de realizar essa apuração, que pode ser manual [5], utilizando fichas escritas, código de barras, identificação por radiofrequência (RFID), entre outros [6]. Entre as opções citadas, a principal vantagem da adoção do RFID é devido ao fato dessa tecnologia não necessitar de contato físico para identificar um material previamente etiquetado, devido a comunicação entre leitor e etiqueta ser realizada por meio de ondas de radiofrequência [7]. ...
... Tradicionalmente, são utilizados códigos de barras no controle das cadeias de suprimentos, mas devido ao aumento de competitividade das empresas em todo o mundo e de buscas por redução de custos e tempo atrelados aos processos, a adoção de sistemas utilizando a tecnologia de Radio Frequency Identification (RFID) surgiu como uma alternativa ao uso do código de barras, tendo em vista que para utilização dos códigos é necessário que os leitores sejam posicionados de forma a ler fisicamente esses códigos, em uma linha de visão clara, ao contrário do RFID que não necessita de conexão física entre etiqueta e leitor, pois essa comunicação é feita por ondas de rádio [6]. ...

Este artigo aborda a adoção da identificação por radiofrequência (RFID) na gestão de vestígios forenses nas centrais de custódia dos órgãos periciais como alternativa eficiente de controle de estoque. O RFID é indicado pois permite o rastreamento de materiais sem necessidade de leitura física, economizando tempo e custos. A lei brasileira 13.964/2019, que alterou o Código de Processo Penal, tornou obrigatória a existência de centrais destinadas à guarda e controle dos vestígios, com sua gestão vinculada ao órgão central de perícia oficial de natureza criminal. Em consequência disso, é necessário utilizar métodos seguros, eficientes e viáveis para controle desses materiais armazenados. De acordo com a literatura, o inventário físico é o método mais eficaz para o controle de estoque, entretanto, sua realização manual é demorada e custosa, especialmente para grandes volumes, e a automatização desse processo se torna uma oportunidade de contornar esse problema. Então, foi analisado o histórico da aplicação dessa tecnologia e seu estado da arte, concluindo-se que o RFID oferece uma solução promissora para a gestão de estoque, proporcionando melhorias substanciais na precisão e eficiência do processo de custódia de vestígios de crimes.

The wide range of applications of deteriorated inventory management in mechatronics. In today's world, every industry uses mechatronics products or techniques to reduce deterioration, which reduces carbon emissions. Since global warming has become a contentious topic, many nations are investing in several projects and supporting environmentally friendly business practices to reduce carbon emissions. The present study analyses a two-warehouse inventory model for deteriorating items with carbon emissions. We included declining products that generated carbon emissions during carrying. Reducing carbon emissions from decaying products during carrying necessitates an exhaustive approach involving several associates in the supply chain and attention to environmental sustainability. So, the firm has invested in green technologies to reduce emissions. The demand rate is price and time-sensitive. Partial backlogging is considered in this model. The consideration of time-dependent holding costs is more practical. A cost-minimizing strategy is taken into account in this model. The main objective of this study is to optimize total cost with green technology investment and total cycle time. Businesses can better manage their decaying goods inventory and reduce the environmental impact of deterioration by optimizing these factors. The model can be solved using an algorithm with the support of MATLAB software (version: R2021b). Using a numerical illustration, the model is described. Also carried out is a sensitivity analysis. The proposed approach is then illustrated with a graphic depicting the optimal solution.

The purpose of the study is to improve the efficiency of the production process of engineering enterprises. The object of study is enterprise engineering. The scientific task is to determine the most optimal RFID technologies to improve the accuracy and efficiency of the production process of engineering enterprises. The technique involves the use of the Saaty method of hierarchies and pairwise comparison. As a result, the most optimal and effective RFID technologies were selected to improve the production process of engineering enterprises through hierarchical ordering of the most significant RFID technologies that affect the production process of engineering enterprises. One limitation of this study is its exclusive focus on RFID technologies, which may not take into account the potential of other technology solutions to improve manufacturing processes. In addition, the use of Saaty's method of hierarchies and even comparison may introduce subjectivity into the selection of optimal technologies, since the results depend on expert assessments. Prospects for further research may include comparison of RFID with other modern technologies that are being implemented in engineering enterprises to ensure greater objectivity and completeness of the analysis. Also, an important aspect of future research could be a detailed analysis of the impact of RFID implementation on the economic efficiency of production and employee workload.

Application of Radio Frequency Identification (RFID) in managing supply chains has witnessed significant interest in recent years. However, the current understanding of the potential benefits that act as the motivating factors/drivers in implementing RFID technology (benefit-drivers), its link to competitive advantage, is fragmented and scattered across the literature. This formed the motivation of this study which seeks to address this gap in the literature through a systematic literature review. Based on a rigorous screening of the literature (2006–2018), the study develops a comprehensive understanding of the various 1) corporate-driven and 2) customer-driven benefit-drivers from RFID implementation. The “2 C” categorization of benefit-drivers is novel and should provide more impetus for practitioners to leverage from RFID implementation. Further, the link between the benefit-drivers and competitive advantage is understood and proposed in the form of a conceptual framework. Finally, avenues for future research are highlighted. The study findings and the framework provide a good starting point for academics and practitioners to further explore the opportunities in supply chain afforded by RFID implementation. A comprehensive review of this kind has not been previously undertaken and constitutes the novelty of this work.

Textile and clothing industry is one of the oldest manufacturing industries and is a major contributor in the economic growth of developing countries.However, from past few decades, it has been criticised for its opaque, unsecuredand untraceable nature of supply chain. Addressing these challenges, the paper proposes a system approach to introduce an item-centric secured traceability concept to monitor and control manufacturing processes and supply chain activities. In order to implement such secured traceabilitysystem,thepaper describestheprocessfor manufacturing, encoding and validating an innovative two-factor secured tag based on particle randomness that is printed on the surface of textile. Being micro-sized, the particles are easy to read and validate with pattern recognition. Further, as achieved through an uncontrolled manufacturing process, the randomness is unclonable to produce counterfeit tags. Furthermore, a sequence of experimental analyses has been conducted using various simulated scenarios to verify its applicability. A secured tag can be a low-cost and durable substitute for detachable, unsecured identifiers commercially available in the market.

The rapid growth of online marketplaces and the advance of Internet technology have enabled manufacturers to more easily engage in direct selling through their own online stores. However, as any retail channel suffers misplacements, the manufacturer's direct sales channel will also face a critical inventory misplacement problem if it chooses encroachment. Radio-frequency identification (RFID) proven to be the most effective technology to eliminate the inventory misplacement problem. This paper investigates the strategic interaction between manufacturer encroachment and RFID deployment decisions in a supply chain consisting of a manufacturer and a reseller. We find that the manufacturers’ encroachment strategies are determined by channels’ misplacement rates, RFID deployment decisions and channel competition intensity. Specifically, the retail (direct) channel's misplacement problem encourages (discourages) the manufacturer to encroach; in addition, if only the retail (if it is direct) channel employs RFID, the encroachment cost threshold increases (decreases) with the RFID tag price; moreover, the more intense the channel competition is, the less likely the manufacturer will be to encroach. Further, when encroachment has occurred, channel competition will be a crucial factor in the direct channel's RFID deployment decision, but it will not affect the deployment of RFID in the retail channel.

We investigate RFID adoption strategies under wholesale price and buy-back contracts in a supply chain with one manufacturer and one retailer who faces inventory misplacement and demand forecast error. RFID can alleviate the misplacement problem, and can reduce demand forecast error by shortening order lead time. By a newsvendor model, we characterise the optimal contract terms in the supply chain without and with RFID adoption, respectively. We further analyse how the contract terms depend on RFID-related parameters (e.g. salable rate and demand forecast error). We find that both without and with RFID, the wholesale price contract will lead to the double marginalisation problem, while the buy-back contract can coordinate the supply chain. We show that the supply chain adopts RFID if and only if the tagging cost is below a threshold; the threshold is in negative correlation to the demand forecast error. The supply chain is more willing to adopt RFID under the buy-back contract than under the wholesale price contract. RFID adoption can sometimes lessen the double marginalisation problem under the wholesale price contract, improving the supply chain efficiency. A smaller RFID tagging cost or a reduced forecast error do not necessarily lead to higher supply chain efficiency.
