基于模糊修正熵权TOPSIS的战时装备供应链风险评估

摘要

According to the characteristics of wartime equip supply chain, long-distance exactitude stroke, enemy raid in rear and influence of bad weather are used to reflect main risk criteria. Based on TOPSIS method with fuzzy ameliorated entropy weight is erected to evaluate the wartime equip supply chain's risk evaluation. Firstly, entropy weight that originated from original data is put forward, which is ameliorated by the experts' factor, and an evaluation method of technique for order preference by similarity to ideal solution is constructed. Finally, the calculation and analysis of an example indicate that this method is easy in calculation, the outcome is reasonable, the subjectivity and randomicity in the commander's decision process are decreased.%针对战时装备供应链的特点,以远程精确打击、敌特后方袭扰和恶劣天气等三个因素为主要风险指标,运用修正的模糊信息熵权对TOPSIS法进行改进,提出了一种新的战时装备供应链风险评估方法.首先利用原始数据产生的模糊信息熵权进行客观赋权,并引入专家因素对权重进行主观修正,利用逼近理想解排序方法进行运算,最后通过实例计算与分析,验证该评估方法简便易行,结论合理,有效降低了指挥员决策的主观随意性.
