基于梯形模糊合作伙伴选择的群体决策方法

Group Decision Method Based on Trapezoidal Fuzzy Partner Selection

针对复杂多变的选择合作伙伴的决策环境,提出基于梯形模糊数的TODIM-PROMETHEE的多属性群体决策框架。首先,将TODIM模型的应用空间拓展到直觉梯形模糊数,利用TODIM中考虑决策者风险偏好的优势增强决策方法中决策者的参与度。其次,结合PROMETHEE ll法,运用优先函数来逐步比较两个对象的优劣关系,解决属性之间的互补性问题,并采用净流量的大小来确定所有对象的排序关系。最后,结合实例,证明此方法的可行性,为选择合作伙伴问题提出一种新的方法。

Aiming at the complex and changeable decision-making environment of selecting partners,a multi-attribute group decision-making framework of TODIM-PROMETHEE based on trapezoidal fuzzy number was proposed.Firstly,the application space of TODIM model was extended to intuitionistic trapezoidal fuzzy numbers,and the advantage of considering the risk preference of decision makers in TODIM was used to enhance the participation of decision makers in decision-making methods.Secondly,combined with the PROMETHEE ll method,the priority function was used to gradually compare the advantages and disadvantages of the two objects to solve the problem of complementarity between attributes,and the size of the net flow was used to determine the ranking relationship of all objects.Finally,the feasibility of the proposed method was proved by an example.A new method is proposed for selecting partners.
