摘要: 针对多属性群决策中属性指标权重的确定,将群体看作由多个被评价且参与权重决策的独立成员组成,提出一种交互式迭代算法,以均等属性权重为起点进入迭代过程,每一次迭代在当前给定的权重参数下求解含参规划模型并计算得到新的权重参数。迭代过程终止于任一群成员在相邻两次迭代的参数权重下加权综合属性值的绝对差异控制在非阿基米德无穷小量以内,此时使用的参数权重即为各属性的最优权重。实际迭代计算过程以及属性指标权重由所有群体成员共同参与和决定,故可以认为最终优化和选择结果为绝大部分成员所接受并满意。通过一个算例以及一个关于研发项目选择的实例,说明该交互式群决策评价方法的可行性和有效性。

Abstract: In this paper, a group is composed of dependent members who are supposed to be evaluated via multiple attributes and participation in determining these attributes' weights. In order to seek the attributes' weights in multiple attribute group decision making, an iterative algorithm is proposed, which starts with equal weights and solves a programming model with weight parameters for each group member to obtain a set of optimal weights. The optimal weights to each attribute decided by every group member are then averaged and used as the new weight parameters in modeling solving during the next iteration. This iterative procedure repeats until for each member, the consecutive weighted average values of all attributes converge within a specified small enough positive value. The optimal attributes' weights of the group are therefore obtained as the current parameter weights when the iteration terminates. Such a set of attributes' weights are jointly determined by all group members, in which sense the related results and decisions are supposed to be accepted and satisfied by all (or at least most) members. A numerical example and an application of R&D project selection are studied to demonstrate the feasibility and effectiveness of the proposed method.
