Research On Multiple Attribute Decision Making Based On Intuitionistic Fuzzy Set And Their Applications In Project Evaluation Of Green Finance Venture Capital

At present,the industrial revolution has entered the era of 4.0.Although it is undeniable that the industrial development has brought great impetus to human society,it has also brought heavy burden to the environment on which we live.Therefore,it has become an important topic to advocate the green revolution of modern industry.Green finance venture capital is a kind of venture capital mainly aimed at environment-friendly projects.In green finance venture investment,the screening and evaluation of projects is a very key link.Moreover,this link often involves many complex and highly uncertain factors,and most of which are qualitative indicators increasing the difficulty.Therefore,this paper focuses on the screening and evaluation of projects in green finance venture capital,and studies the construction of intuitionistic fuzzy multiple attribute decision making model based on prospect theory and its application in the project evaluation of green finance venture capital.After analyzing the operation process and project screening process of green finance venture capital,a new project evaluation index system of green finance venture capital is constructed based on the existing references and investigations.The novel system contains 15 indicators in 5 levels.According to prospect theory,three models are proposed,including IF-PT-TODIM model,IF-PT-MABAC model and IF-PT-EDAS model.In these three models,the initial assessment information is verbal for convenience,and the linguistic information is transformed into intuitionistic fuzzy numbers in line with the intuitionistic fuzzy evaluation scale during data conversion.Moreover,for the integrality of the proposed models in this paper,we not only propose the method for determining expert weights by using entropy weight method,but also introduce the mixed weight method to calculate attribute weights.In other words,using the balance between subjective weights given by experts and objective weights determined by the CRITIC method ensures that attribute weights are more scientific and reasonable.Eventually,the models proposed in this paper are successfully applied to the project evaluation of green finance venture capital.What’s more,the validity and stability of these models is proved through sensitivity analysis and comparative analysis.
