Abstract:Knowledge innovation in the supply chain is a complicated relation route network; process of innovation delegate the convergence of capability and demand.First,this paper presents a summary of the characteristics of knowledge innovation in the supply chain; then knowledge in the supply chain is described as knowledge flow coupling each enterprise.Three conclusions are drawn as following:①Supply chain members should cooperate to realize knowledge sharing;②Knowledge transfer and knowledge conformity can be used to update knowledge;③Supply chain members should continuously innovate to improve knowledge level.According to multiattribute group decisionmaking problems dealing with knowledge innovation in the supply chain,the procedure of decision making for knowledge innovation in the supply chain based on multiattribute decisionmaking model is discussed and explained with an example.Finally,the future possible research direction is proposed.
