Comprehensive Benefit Evaluation Of Iron And Steel Enterprises From Transit To Rail Based On Extension Cloud Model

With the convening of the 20 th National Congress,promoting the harmonious coexistence between man and nature and promoting the green concept is more deeply rooted in the hearts of The proportion of road transportation in comprehensive transportation structure is far greater than that of railway transportation However,there are some problems in highway transportation,such as high cost and high pollution The imbalance of transportation structure can’t pollute and realize the purpose of green transportation,and it can’t pursue beauty and high in China.At present,the public transit railway has become the main policy for the transportation structure to reduce costs and increase efficiency and win the blue sky defense war Iron and steel enterprises in the main field of railway revolution have made progress,but the proportion of road freight transportation still ranks first,which affects the realization of the goal of "double carbon" and even affects the high level of iron and steel enterprises A thorough study of the internal causes of the progress of iron and steel enterprises in revolving iron and steel shows that the lack of relevant research on the comprehensive benefits of iron and steel enterprises in revolving iron and steel directly affects their enthusiasm In this thesis,the comprehensive benefits of iron and steel enterprises are evaluated Based on the relevant literature and referring to the research results at home and abroad,the comprehensive benefit evaluation system of iron and steel enterprises is established Construction of evaluation model based on extension cloud model provides reference value for comprehensive benefit evaluation of iron and steel enterprises.This thesis mainly includes five aspects.First,it introduces the research background and significance of iron and steel enterprises,the research status at home and abroad,and the research technology roadmap Secondly,it unfolds the related theories and statements,and clarifies the enterprise high triple bottom line theory,value theory and extension cloud model used in this thesis Thirdly,it makes a comprehensive investigation on the comprehensive benefit index of iron and steel enterprises,that is,it makes a deep analysis from the perspective of economic and social benefit influencing factors With the help of literature,using membership and rationality to construct the comprehensive benefit evaluation index system of iron and steel enterprises Fourthly,through G1 method and Critic method,the subjective and objective weights of the comprehensive benefit index of iron and steel enterprises are calculated,and the combined weights are determined by game theory.Combined with extension cloud model,the comprehensive benefit evaluation model of iron and steel enterprises is constructed Fifthly,the comprehensive benefit evaluation model of revolving railway in iron and steel enterprises is substituted into R iron and steel enterprises for case study,and it is concluded that the comprehensive benefit grade of revolving railway project in R iron and steel enterprises is in Grade IV(good),and its comprehensive benefit is mainly guided by economic benefit,and social benefit and benefit play an auxiliary role.Based on the theory of extension cloud,the comprehensive benefit evaluation model of iron and steel enterprises is constructed,which provides a new perspective for the comprehensive benefit of iron and steel enterprises,and constructs a feasible comprehensive evaluation model for the comprehensive benefit of iron and steel enterprises It has profound significance for the high and low carbon transformation of steel industry and transportation industry.
