Estimating Data Volumes of RFID-enabled Supply Chains

The widespread application of RFID tags in supply chains is said to cause enormous data volume problems and thus unprecedented challenges for systems and infrastructures. In order to unleash the potential of item-level RFID applications, such as data sharing and discovery across company boundaries, an unbiased understanding of emerging data volumes is necessary. However, quantitative data that provides factual argument is still scarce. Therefore, we present a simulation study based on a real-world scenario that reveals quantitative characteristics of the data volumes problem in an RFID-enabled supply chain and discuss its implications. Our results suggest that data volumes will be much lower than currently anticipated, but still bear significant challenges for researchers and developers of RFID infrastructures

A highly accurate and scalable approach for addressing location uncertainty in asset tracking applications

Tracking systems that use RFID are increasingly being used for monitoring the movement of goods in supply chains. While these systems are effective, they still have to overcome significant challenges, such as missing reads, to improve their performance further. In this paper, we describe an optimised tracking algorithm to predict the locations of objects in the presence of missed reads using particle filters. To achieve high location accuracy we develop a model that characterises the motion of objects in a supply chain. The model is also adaptable to the changing nature of a business such as flow of goods, path taken by goods through the supply chain, and sales volumes. A scalable tracking algorithm is achieved by an object compression technique, which also leads to a significant improvement in accuracy. The results of a detailed simulation study shows that our object compression technique yields high location accuracy (above 98% at 0.95 read rate) with significant reductions in execution time and memory usage.Rengamathi Sankarkumar, Damith C.

Returns Management for Time-sensitive Products: What is the Value of RFID and Sensor Technologies?

This contribution concerns itself with the value of RFID and sensor technologies to reverse logistics processes. Our research is motivated by the question, to what extent the accuracy of information on product quality delivered by such technologies impacts the total recovered value companies obtain from returned goods in an industry with time-sensitive products. For this purpose, we first present a case study to examine the returns management process at a manufacturer of high-tech consumer electronics. We then develop an analytical model to study the monetary benefits in a scenario with RFID-enabled product disposition. Our results first show that RFID allows for a redesign of the return process which performs more efficiently regarding total recovered value depending on technology costs (i.e. tag costs) and capabilities (i.e. sufficient sensor-delivered parameters to rightly infer the product quality). Second, our results indicate that maximum benefits can be drawn with lower accuracy but early decision on the disposition option

Business process and technology lessons learned, recommendations and best practices for new adopters

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2006."June 2006."Includes bibliographical references (leaves 117-118).This thesis focuses on documenting learnings from a RFID data exchange pilot in the fast moving consumer goods industry. The pilot we studied is a collaborative effort between two of the largest retailers in the world and five of their major suppliers, facilitated by EPCglobal and the MIT Auto-ID labs. Currently, manufacturers and suppliers are building the infrastructure to exchange EPC data to validate standards and proof of concepts for RFID adoption. The outcome of these pilots will essentially set the stage for large scale RFID adoption worldwide. Our thesis attempts to document issues relating to data exchange from business process, organizational and technical perspectives. We have synthesized the findings and consolidated the lessons learned during the pilot in an attempt to form a set of actionable recommendations for new companies looking to start on RFID pilot projects.by Rida Chan [and] Sangeeth Ram.M.Eng.in Logistic

Challenges of Tagging Goods in Supply Chains and a Cloud Perspective with Focus on Some Transitional Economies

This paper considers some of the barriers in implementing the RFID (radio frequency identification) technology for identifying, locating, tracking and tracing goods in supply chains, along with a model for adopting cloud services that can mitigate these obstacles in the transitional environment. The analysis is based on the assessments of the implementation impediments, given by the experts in the field of logistics: university professors, assistants and entrepreneurs from three Western Balkan countries (Montenegro, Serbia, and Bosnia and Herzegovina). Since the professionals’ assessments are influenced by their experiences from the transitional economies, which are faced with limited abilities to invest in expensive business information systems, the main hypothesis is that moving the logistics into the cloud may resolve or at least alleviate the considered problems. On the basis of the available secondary literature resources on pros and cons of RFID implementation into supply chains, and the statistical analysis of the consciously completed questionnaires in the survey, the model for adopting cloud services for providing RFID-enabled goods and related activities in the considered economies is proposed at a logical level. The paper also gives some directions for further research work in this domain

Visibility in multimodal maritime container transport chains - Logistics service providers' perspective

Nowadays, transparency and digitalization of actions in the whole supply chain are emphasized and firms are demanding visibility to better forecast, plan and control the flow of goods. The expectations towards fully real-time traceable cargo flow are high and logistics service providers are recommended to digitize their actions to stay in the highly competitive freight transport markets. When it comes to technology, it has been developed rapidly and can provide very sophisticated solutions to enhance visibility. Information flow is a key for visibility. Therefore, information and communication technology (ICT) is vital to enhance visibility. However, technology alone does not enable visibility. It requires collaboration with other involved actors in the transport chain. Multimodal maritime container transport chains are complex in a sense that they require deep collaboration in a form of IT-compatibility with vast number of players involved within the carriage of goods to enhance seamless and automatized exchange of information. It has been disclosed that the biggest logistics service providers have already been able to form such collaborative relationships with big shipping lines, for instance. Also, market leaders usually arrange the pre- and end-haulage of the transport with own assets and therefore information flow is advanced. However, freight transport industry is highly fragmented and majorly consists of small-sized firms. Margins in the freight transport markets are extremely low as customers do not see added value in freight transportation and therefore transportation is seen as an extra harmful cost for firms. Therefore, the idea of big IT-investments and integration of actions with other players is infeasible for some companies. In this study, visibility in multimodal maritime container transport chains is investigated in a wide sense by conducting semi-structured interviews among different-sized logistics service providers located in Finland. First, the current adoption of visibility is studied, the benefits of it are discussed and the barriers to adopt visibility are discussed. Furthermore, perceptions towards the importance of visibility as a service offering in the creation of competitive strategies are investigated
