Node importance evaluation for supply chain network based on weighted improved node contraction method
摘要
Abstract
Aiming at the significance of node importance evaluation and insufficient of existing node contraction method in node importance evaluation of complex networks,this paper proposed a weighted improved node contraction method for supply chain network.Through the improvement of weight determination method using triangular fuzzy number,it evaluated the node importance by the node itself and its neighborhood relations.Based on the analysis of comparative importance,it illustrated the advantage of the improved method in solving the problem that different nodes had the same importance.By the improved method,it evaluated the node importance of coal supply chain.The results show that sea port has the highest importance in the supply chain which are in conformity with the practical situation and have demonstrated the accuracy and efficiency of the proposed method.关键词
