Study On Green Performance Assessment Of Retired Construction Machinery Remanufacturing Process Based On Information Tracing

Owing to the heavy weight of most of the construction machinery, itsremanufacturing can significantly improve the utilization of resources recycling andgreatly contribute to the environmental pollution reduction. Currently, for lacking ofrecycling and dismantling and other related information of the retired productcomponents of the construction machinery remanufacturing enterprises, it is difficultto achieve comprehensive green performance assessment for retired productcomponents in remanufacturing process. Therefore, the retired constructionmachinery remanufacturing process information management is studied and the greenperformance assessment of the remanufacturing process is proposed based oninformation tracing in this paper.Firstly, this paper takes certain construction machinery remanufacturingenterprise as an object, analyzes the overall business process and present s thesituation of remanufacturing, proposes the requirement for information managementsystem. The remanufacturing business process is optimized based on the overallbusiness process. Then， the overall system function modules，the tracing informationmanagement and evaluation decision support module which are core modules ofsystem are designed. Secondly, in order to realize the maximum environmental andeconomic benefits, a multi-attribute utility decision method is put forward to build thegreen performance assessment of multi-objective decision-making model whichutilizes the total utility value to measure the size of the green performance. Then,the green evaluation index system with the thought of integrating life cycleassessment and life cycle cost assessment is built. Finally, the paper takes an engineremanufacturing repair scheme as an example, the calculation process of green utilityvalue for the remanufacturing repair is analyzed based on the tracing information. Theresults show that the total utility value can directly reflect the green property of theprograms, and assist remanufacturing enterprises to choose the optimal treatment andthe selection of different remanufacturing process technology.
