摘要
针对目前PPP融资模式选择中存在主观性、变动性的问题,基于犹豫模糊集理论构建PPP融资模式选择群决策模型.该模型从经济性、适用性、风险性和复杂性出发构建决策指标体系;用专家法定权重和专长权重相结合的方式确定初始权重;采用犹豫模糊数表达专家决策偏好信息,提高了PPP融资模式方案选择决策的有效性、合理性;设立群体共识阈值指标,并通过同时调整专家权重和个人偏好的方法提高专家共识水平,根据得分函数得出最后共识水平下的方案排序.通过某城际铁路项目的算例分析可知该模型方法能够更加准确、有效地选出合适的PPP项目融资模式.
In view of the problem of subjectivity and variability in the current PPP financing mode selection,based on the hesitant fuzzy set theory,the decision model of PPP mode selection group is constructed.Based on economy,applicability,risk and complexity,the model constructs a decision index system.The initial weight is determined by the combination of expert legal weight and expertise weight;the preference information of expert decision is expressed by hesitant fuzzy number,which improves the validity and rationality of PPP financing mode scheme selection decision.Setting up threshold index of group consensus and improving the level of expert consensus by adjusting expert weight and individual preference at the same time.According to the scoring function,the scheme rankings of the final consensus level is obtained.Through an example analysis of an intercity railway project,it can be concluded that the model method can select the appropriate financing mode of PPP project accurately and effectively.
