摘要
准确识别粮食供应链网络的关键节点,对保障国民粮食安全具有重要的现实意义。研究将粮食供应链抽象成一个复杂网络,提出一种基于多属性综合评价的粮食供应链网络关键节点识别方法。该方法综合考虑网络的度中心性、介数中心性、接近中心性和特征向量中心性等指标,借助熵权法赋予各指标权重,避免主观因素产生的偏差;将灰色关联分析引入多准则妥协解排序法来综合评价粮食供应链网络的节点重要性,并通过风筝网络和Karate网络验证方法的可行性和有效性。最后,使用该方法对粮食供应链网络进行关键节点识别,结果表明该方法可有效识别粮食供应链网络的关键节点。
ed the grain supply chain into a complex network and propose a method for identifying key nodes of grain supply chain networks based on multi-attribute comprehensive evaluation.The method integrated the importance indicators such as degree centrality,mediator centrality,proximity centrality and feature vector centrality of the networks,and assigns weights to each indicator with the help of entropy weighting method to avoid the bias generated by subjective factors;grey correlation analysis was introduced into the multi-criteria compromise solution ranking method to comprehensively evaluate the node importance of the grian supply chain networks,and the importance of the nodes was evaluated by the kite network and Karate network to verify the feasibility and validity of the method.Finally,the method was used to identify the key nodes of the grian supply chain networks,and the results showed that the method can effectively identify the key nodes of the grian supply chain networks.
