基于Entropy-Topsis模型的光伏建筑项目投资风险测评

摘要

采用Entropy－Topsis模型，从政策、经济、技术和自然环境等维度，对我国8个典型光伏建筑项目（BI-PV）的投资风险水平进行评价与分析。一方面，采用Entropy法确定测评指标的客观权重；另一方面，运用Top-sis方法对BIPV项目应承担风险的大小进行量化、排序，并运用灰色关联分析法诊断关键影响因素，以期为我国BIPV项目投资风险管理提供一定的参考依据。%This paper evaluates the investment risk level of 8 typical building integrated photovoltaic projects (BIPV ) through Entropy-Topsis model,from the dimensions of policy,economic,technical and natural environment. The paper uses the Entropy method to determine the objective weight of evaluation index,then quantifies and sorts the risk of BIPV projects by Topsis method. Finally,the paper determines the key influence factors by grey correlation analysis method and provides some reference for BIPV project investment risk management in our country.
