基于模糊多准则群决策的可持续项目选择模型

将模糊多准则群决策方法应用于可持续项目的选择决策中。首先构建可持续项目选择框架,包括投资的经济、社会和环境影响以及战略联盟、组织准备和投资风险六个评价准则。由于该框架的准则权重很难通过一组决策者不一致的偏好而确定,所以,运用乘法偏好关系和模糊偏好关系收集决策者对准则权重的偏好,利用目标规划方法进行建模并确定各个准则的相对权重;然后用模糊TOPSIS方法评估投资机会的适合程度。TOPSIS方法是基于偏好比率的一种决策方法,其中偏好比率运用于模糊数排序和模糊距离测量,可以有效地计算出每个备选方案与理想方案的模糊距离,从而根据距离判断其亲密系数,并最终应用于最佳方案的抉择。最后,以某投资集团的可持续投资项目选择问题为例进行分析,验证了方法的有效性和可行性。

A Hybrid Fuzzy Multiple Criteria Group Decision Making Approach for Sustainable Project Selection

In this paper, fuzzy multi criteria group decision has been applied on sustainable project selection decisions. First, a comprehensive framework, including economic, social, and environmental effects of an investment, strategic alliance, organizational readiness, and risk of investment has been built for sustainable project selection. As the relative importance of the criteria of the proposed framework are hard to find through several conflictive preferences of a group of Decision Makers so, a goal programming has been supplied to this aim considering multiplicative and fuzzy preference relation. Then, a fuzzy TOPSIS method has been developed to assess the fitness of investment chances. TOPSIS method is based on preference rate, which is used for ranking fuzzy numbers and fuzzy distance measurement. So preference rate can effectively calculate the distance from each alternative to fuzzy ideal solution. According to the distance, we can know the fuzzy close coefficient, and finally choose the best solution applied. At last, Taking the investment project selection of XXX investment as an example, the validity and feasibility of the method are verified.
