Radio frequency identification (RFID) technology introduces the opportunity for increased visibility by facilitating easy tracking and identifying of goods, assets and even living things. However, high investment cost and inadequate technical capability remain as challenges for RFID system implementations. That being the case, fair evaluation of savings associated with increasing performance and investment costs has a great role in the success of RFID projects. In this study, a systematic framework for the economic analysis of RFID investment is proposed. The increment of order is determined in terms of delivery accuracy and delivery time via a fuzzy rule based system. A case study is constructed on the basis of expert conception to illustrate the proposed method.
