【摘要】：随着社会的发展,工程项目投资方案选择所受的影响因素越来越多。方案的属性值呈现出不确定性、模糊性的特征。文章对工程项目投资方案的主要影响因素进行了系统全面的分析,构造出影响因素的指标体系(即属性集)。为应对不确定信息和降低决策者的决策难度,让决策者利用所构建的语言变量给出方案属性值的定性判断,然后利用所构建的语言变量和三角模糊数之间的对应关系,将其转化为相应的三角模糊数,从而得到相应的定量模糊判断。为得到最优的综合投资方案,同时考虑属性间的交互作用,文章利用非可加测度及广义λ-Shapley Choquet积分来计算投资方案的综合评价值,属性权重由广义Shapley函数确定。基于此,给出了工程项目投资方案选择的一个新评价方法。最后,通过一个实际案例分析来验证所给方法的可行性和有效性。
[Abstract]:With the development of society, more and more factors affect the choice of project investment scheme. The attribute value of the scheme is characterized by uncertainty and fuzziness. This paper makes a systematic and comprehensive analysis of the main influencing factors of the project investment scheme, and constructs the index system of the influencing factors (I. e., attribute set). In order to deal with uncertain information and reduce the difficulty of decision making, the decision makers can use the constructed language variables to give the qualitative judgment of the scheme attribute value, and then use the corresponding relationship between the constructed language variables and triangular fuzzy numbers. It is transformed into the corresponding triangular fuzzy number, and the corresponding quantitative fuzzy judgment is obtained. In order to obtain the optimal comprehensive investment scheme and consider the interaction between attributes, the non-additive measure and the generalized 位 -Shapley Choquet integral are used to calculate the comprehensive evaluation value of the investment scheme. The attribute weight is determined by the generalized Shapley function. Based on this, a new evaluation method of project investment scheme selection is given. Finally, the feasibility and effectiveness of the proposed method are verified by an actual case study.
