基于主成分分析和三角模糊数的应急物资供应能力指标体系

Index System of Emergency Material Supply Capability Based on Principal Component Analysis and Triangular Fuzzy Number

为深入研究应急物资供应能力内涵及变化演化规律,从功能、要素、系统等多维视角构建由指挥运筹能力、物资筹措能力、物资供应能力、信息管理能力4个维度构成的应急物资供应能力体系;基于主成分分析法对指标体系进行约简和优化,利用三角模糊层次分析法确定各级指标的权重。结果表明,该体系可为应急物资供应能力的优化研究提供理论支持。

In order to deeply study the connotation and evolution law of emergency material supply capability,an emergency material supply capability system is constructed from the perspectives of function,element and system,which consists of four dimensions:command and operation research capability,material financing capability,material supply capability and information management capability;the index system is reduced and optimized based on principal component analysis,and the weights of indexes at all levels are determined by triangular fuzzy analytic hierarchy process.The results show that the system can provide theoretical support for the optimization of emergency supplies supply capacity.
