摘要
虚拟企业在帮助企业获得反应灵活性的同时,也不可避免地蕴涵了诸多风险因素。在分析虚拟企业风险评价应该考虑的主要因素的基础上,建立了一套适用于虚拟企业风险评价的指标体系。并以三角模糊数的形式给出指标值和评价者的主观感觉值,将基于期望值的模糊多属性决策法引入虚拟企业的风险评价中。同时讨论了指标权重完全未知和部分未知时虚拟企业的风险评价问题,得到虚拟企业方案综合选择的优先顺序。实例说明了虚拟企业风险评价的具体过程。
Virtual enterprise can help enterprises gain response flexibility,but meanwhile,it unavoidably contains many risk factors.A set of index system is established for the risk appraisal in virtual enterprise on the basis of some main factors considered when analyzing appraisal of risk.The index value and the subjective feeling of the estimator are given in the form of triangular fuzzy number, Fuzzy multi-attribute decision making method,which is based on expected value, is introduced to the risk appraisal of virtual enterprise.In addition,the issue of risk appraisal in virtual enterprise is also discussed when the index weight is completely unknown or partly unknown,and in this way,we get the priority in all the schemes of virtual enterprise.The course of risk appraisal in virtual enterprise is illustrated by a example.
