Proposal on EPC system enhancement to realise supply chain process analysis

摘要

Although IT services for business process analysis have become popular, they do not cover the business process of the Supply Chain Management (SCM), since information in the real space is difficult to capture by existing IT systems. Therefore, process analysis for the item moves in the supply chain also is not commonly used. Assuming the use of Electronic Product Code (EPC) system, an implementation of networked RFID systems, this study proposes two supply chain process analysis methods, a performance analysis method and an anomaly analysis method. In addition, this study proposes a way to enhance EPC system with Hadoop system to meet the needs for massive transaction data processing. The proposal is evaluated using an agent-based simulation tool, and the feasibility of the business process analysis methods as well as system enhancement is confirmed.
