Comprehensive evaluation of distribution network project cost management level based on optimized random forest

Abstract

AbstractIn this article, by analyzing the content and characteristics of the cost management of the distribution network project, the evaluation index system of the cost management level is formulated first. Gini index in random forest algorithm and analytic hierarchy process are used to analyze the influencing factors of the cost management level of distribution network project from quantitative and qualitative aspects. The results show that design change and on‐site visa management have a great impact on management level, while project advance payment management has a relatively small impact. Based on the above analysis results, this article simplifies the indicators, so as to optimize the random forest model. After verification, the optimized model can improve the efficiency of evaluation, on the other hand, it can effectively improve the accuracy of evaluation, ensure the scientificity of evaluation, and provide reference for improving the cost management of distribution network project.
