AbstractPurpose -This paper aims to explore and describe the impact of radio frequency identification (RFID) technology on inventory accuracy within a production and assembly plant, and to propose a model for assessing the impact of the technology on inventory accuracy. Design/methodology/approach -The empirical investigation, based on case study research, focuses on an RFID implementation at a supplier of injection-moulded, surface-treated plastic to the automotive industry. This implementation is one of the few item-level, open-loop RFID implementations in the automotive industry. Findings -The empirical paper provides insights into, how inventory accuracy has been improved and made attainable in practice by implementing RFID, and indicates that the technology ensures inventory inaccuracy will be kept at a minimum. As a result, an analytical model is presented which identifies the impact of RFID technology on inventory accuracy. Research limitations/implications -The case study and context need to be considered when generalising upon the findings. Furthermore, it is hoped future research could further develop the model presented and test it against implementation practice. Practical implications -RFID technology provides practitioners with the opportunity to eliminate waste, and improve production and assembly performance. The research provides practitioners with experience of, and insights into how a production and assembly plant has improved inventory accuracy by implementing RFID technology. In particular, practitioners are provided with a model which enables them to assess the impact of RFID on inventory accuracy. Originality/value -This paper contributes to the RFID community by providing empirical insights into the impact of RFID technology on inventory accuracy, but also more broadly into logistics and operations management research.
This master thesis has been carried out in Next Generation Innovative Logistics (NGIL), which is a VINN Excellence Center based at Lund University sponsored by Vinnova, the Swedish Governmental Agency for Innovation System. III ACKNOWLEDGMENT I would like to show my gratitude to my supervisor, Daniel Hellström, at the packaging logistics division at LTH for his expertise, help and suggestions and for his support during this thesis.I would also like to express thanks to Mikael Erlandsson at Plastal and Olle Hydbom at RFID Constructors for supplying me with the information and data I needed to complete this thesis.Last but not least, a big thanks to my family for giving me hope and strength and support through this thesis. This thesis couldn't have been done without your support. RFID technology has become very popular in recent years (1). It is said to have potential to increase the level of automation (2), reduce the labor levels and to improve the supply chain in areas such as inventory, visibility etc. (3) (see chapter 1.2.1 for more examples). PAGO is one of the first major companies in Sweden that have implemented an open-loop RFID system (see chapter 1.2.3.2) that tag on item level. They are also a supplier of injection-molded and surfacetreated plastic to the automotive industry; an industry that is characterized by high level of automation and fierce competition. It is thus very interesting to investigate why and how PAGO implemented RFID technology; did any problem arise? How did they solve them? What where their underlying reasons?To minimize the errors caused by manual updating -resulting in incorrect storage levels -PAGO have implemented a RFID system. The system has 24 RFID gates, divided into seven places: injection molding, entry and exit point of high storage 1, paint shop, entry and exit point of high storage 2 and after the sequencing process. The RFID system will help reduce the effects of entering the wrong quantity at the entry and exit point for high storage 1 and 2. It will also reduce the effects of specifying the wrong color or product. Furthermore, it will also help them verifying that each product is correctly assembled.During the implementation, PAGO encountered some problems with ESD, reading too much or too little, tags becoming partially or completely detached and a long installation time. Most of these problems have been fixed but some of them remain.There exist several reasons why PAGO implemented a RFID system, other than verifying the assembly and minimizing the effect caused by manual updating. One of those is believed to be because of the nature of the company -They only have 8h to sequence deliver the order, high turnover rates with expensive products and highly automated processes. Another reason is that RFID was a solution that solved both of their specified problems, but also supplying them with more features. Other reasons are that it will probably become a demand from Volvo in the future and that the technology is more future proof than any other technology that would ha...
