Performance evaluation of supply chain is complex and of uncertainty, and is influenced by factors of multiple levels. Directing at the features mentioned above, this paper studied the performance evaluation of supply chain of multiple attributes, and put forward a performance evaluation model and algorithm of supply chain based on extension correlation function. Via analysis of relative factors in the process of performance evaluation of supply chain, the model gave out an index system of performance evaluation of supply chain and by standardization of different evaluation indexes, it built an improved extension correlation function between evaluation indexes of enterprise supply chain performance and the ideal range of supply chain performance. Thus, the comprehensive weighted extension goodness between enterprise supply chain performance and the ideal range of supply chain performance could be obtained. According to the value of comprehensive weighted extension goodness, the supply chain with the optimal implementation effect could be selected, so as to offer effective support for the follow-up implementation of supply chain. Finally, in order to offer a scientific method for improving the supply chain and the enterprise competitiveness, the model and algorithm was tested an actual case.
