Research On Green Performance Evaluation Of Re-manufacturing Enterprises Based On The Fuzzy DANP-improved Grey Correlation Method

Under the background of the transformation of national industrial structure,realizing health,fast and sustainable development of economic,the remanufacturing industry has attracted wide attention because of its advantages like saving resources,reducing cost and pollution.The research on re-manufacturing has also become a hot spot in the field of scientific research.However,most research is confined to a single sub-process in re-manufacturing or only to consider economic benefits.On the basis of the existing research results,this paper combines the development characteristics of China's re-manufacturing industry,and extracts 20 influential factors from five dimensions of re-manufacturing capacity,recovery ability,economic benefit,ecological benefit and green management system to build up a green performance evaluation system for re-manufacturing enterprises.Considering that there is a complex interaction relationship among the influencing factors of the evaluation system,the fuzzy DEDEEL-ANP(DANP)method is used in combination with the method of the fuzzy DEMOEL(Decision Making Trial and Events Laboratory,Decision-Making Laboratory Method)and ANP(Analytic Network Process,Network Analysis)method.And the effect relationship between the factors and the weight value of each index on the global action are obtained.From these two perspectives,the key influential factors in the enterprise's green performance evaluation system are analyzed,and the effectiveness and stringency of the research achievements are guaranteed.On the basis of the relative weight value of influencing factors in the evaluation system calculated by the fuzzy DANP method,using the improved grey relational analysis method to evaluate four re-manufacturing enterprises,the grey scale is calculated from two angles of ideal value and tolerance value,then the evaluation index of each enterprise is obtained.The optimal scheme is selected to avoid the deficiency of only calculating the ideal value of the grey scale in the traditional grey relational analysis method,so that the evaluation result is more scientific and reliable.Re-manufacturing industry green performance evaluation plays an important role in realizing green reform and promoting sustainable development.It provides reference for the government's policy of re-manufacturing industry development,inspiration for the industry to make re-manufacturing standards,a theoretical basis for enterprises to guide the implementation of green economy through re-manufacturing.
