Dynamic Appraisal Model for Supply Chain Performance Based on Extension Theory

Measuring the performance of supply chain is a difficult task. The purpose of this paper is to provide a dynamic appraisal model for supply chain performance based on extension theory. The appraisal system of supply chain performance is represented by matter-element method and extension analysis in extension theory. The dynamic appraisal model for supply chain performance based on extension theory is created. Range of index value is depicted by classic region and segment region, relation function is used to do level appraisal. At last the feasibleness and maneuverability of model is verified by experiments. The model has the character of reflecting supply chain dynamically operation
