Development of traceability system for attribute information identification

Abstract

In this paper, we introduce a traceability system which consists of three layers: Physical Logistics, ERP and Independent Data Management layers. Physical Logistics layer manages and records information which allocates production plan and material inventories. ERP layer deals with main core of business information, such as order, purchase, production and shipment. At Independent Data Management layer, entire information is gathered both from ERP layer and Physical Logistics layer. Independent Data management layer also produce inter-company traceability information. We have implemented an experimental prototype system and applied to tradings data based on seafood supply chain scenario. Each material and product is identified with Radio Frequency Identification (RFID) tags. Users including consumers can obtain precise traceability information such as manufacturing and distribution through web application. We have applied purchase information for 8 weeks at distributors to the system and confirmed that the system works accurately.
