考虑愿景的动态多属性群决策共识模型

A consensus model for dynamic multiple attribute group decision making considering aspiration-levels

摘要:

现实中很多的多属性群决策(MAGDM)问题常常具有以下特征：(1)决策者使用个人属性集和愿景集来评估各自的备选方案集,并且个人属性集和愿景集可以异构。(2)决策者不必就属性集和愿景集达成共识。(3)个人属性集、方案集和愿景集可以动态变化。通过将上述实际情况的特征纳入MAGDM,提出了一种考虑愿景的动态多属性群决策共识模型及其解决框架,设计了集体解决方案的选择过程和共识达成过程的算法,给出了为达成共识对个人属性集、个人方案集、个人偏好和个人愿景集的调整建议,并结合实例加以说明。与现有的MAGDM模型相比,本文方法考虑了决策者的动态愿景并提供了灵活的决策框架,使决策过程更贴近现实。

Abstract:

Many real-world multiple attribute group decision making problems (MAGDM) have the following characteristics: (1) Decision makers use individual attribute sets and aspiration sets to evaluate their alternative sets, in addition, the individual attribute sets and aspiration sets can be heterogeneous. (2) Decision makers don’t have to reach a consensus over attribute sets and aspiration sets. (3) Individual attribute sets, alternative sets and aspiration sets can be dynamically changed. With these characteristics of the actual situation included in MAGDM, this paper proposes a consensus model for dynamic multiple attribute group decision making considering aspiration-levels, and proposes its resolution framework. We have designed a selection process of the collective solution and the algorithm of consensus reaching process, and proposed adjustments to individual attribute sets, alternative sets, preferences and aspiration sets to achieve consensus. Compared with the existing MAGDM model, this method considers the dynamic aspirations of decision makers and provides a flexible decision making framework so that the decision making process can be much closer to reality.
