基于AHP模糊优先权的虚拟企业伙伴选择方法

对于虚拟企业伙伴选择时存在不一致区间判断的复杂评估问题,在AHP框架下运用有下限和上限的区间数表示候选伙伴之间的比较比率,引入模糊集的隶属度函数表示对选择方案的满意程度,构造模糊约束集合矩阵,利用线性规划求解具有最大满意程度的优先权矢量,得出候选者的总体优先顺序,并举例说明了应用这个方法的计算过程.

Virtual Enterprise Partnership Selection Method Based on AHP Fuzzy Preference

Virtual enterprise partnership selection is a complex evaluation process, while the judgment includes inconsistency and interval. In the framework of Analytic hierarchy process, this paper firstly presents the comparison ratios between alternative partners as intervals with lower and upper bounds to capture the uncertainty and inconsistency experienced by the decision-maker. Secondly, the membership function of fuzzy set denotes the degree of satisfaction with a given solution. Then, a fuzzy constraint matrix is constructed. Lastly, the linear program is applied to find the priority vector that has a maximum degree of membership. And the global priorities of all alternative partners are calculated. A numerical example is given to illustrate the application of this method.
