基于直觉模糊集的公私合营项目方案选择
|
摘要
项目方案的选择是PPP项目研究中的棘手难题。文章用区间直觉模糊数代替实数,以减少信息的损失,而后采用模糊测度代替权重以表示评价指标的重要性,并基于区间直觉模糊Choquet积分算子构建基于直觉模糊集和模糊测度的多属性决策方法来实现PPP方案的最优选择。最后通过实例分析验证了模型的有效性。
The project scheme targets the difficult problem in PPP project research. This paper uses interval intuitionistic fuzzy number as a substitute of real number to reduce the loss of information and then uses fuzzy measure instead of weight to express the importance of evaluation index. Based on the interval intuitionistic fuzzy Choquet integral operator, a multi-attribute decision making method based on intuitionistic fuzzy set and fuzzy measure is constructed to realize the optimal choice of PPP scheme. Finally, the effectiveness of the proposed model is verified by a case study. The paper effectively solves the problem of information loss and the independence between evaluation indexes in project program decision making, which greatly improves the rationality and scientificity of decision making,and provides a reference for project decision makers in program selection.
