A CBR model for knowledge sharing in supply chain based on generalized rough set

Simple information sharing is inadequate for the supply chain management today. In this article we put forward a R⁵ model for knowledge sharing instead of information sharing in supply chain, which combine the CBR´s characteristic that can make best use of information on hand with the RS´s strong function in data mining, thereby set up a sharable knowledge base among the supply chain to elevate the finally product (including service)´s competence.
