Research On Green Product Design Scheme Selection Based On QFD And CBR

Under the background of sustainable development,green product is paid more and more attention by governments and accepted by consumers.Green product has been the core competitiveness of enterprise.Therefore,selecting the green product design scheme which can satisfies customer and environment is particularly important for enterprise.But there is still lack of research on green product design scheme selection.One is the evaluation index system and weight calculation.Although domestic and overseas scholars have done many researches,they don't consider the information of requirement when establish the evaluation index system and calculate the indexes' weight.Secondly,the existing green product design scheme selection methods don't consider decision maker's expectation.Therefore,we should do more research on green product design scheme selection from the two aspects.In this paper,the study aims to deeply research on green product design scheme selection problem based on analyzing related theories of green product design,QFD and CBR.The purpose and meaning of the study lie in: on one hand,to provide a method for green product design scheme selection based on QFD and CBR in terms of existing research;on the other hand,to verify the reasonability and effectiveness of the proposed method via a actual case.This article has mainly completed three aspects as follows:Firstly,related concepts and theories are analyzed.This thesis analyzes the concept and characteristics,method and relevant research problems of green product design,the concept and theories of QFD and its applied areas,and the concept and theories of CBR and its applied areas.The analysis is the foundation for further green product design scheme selection.Secondly,the framework and method for selecting green product design scheme are given.QFD is an effective way to integrate the information of requirements into evaluation index system and weight calculation.After determining the evaluation index weight,CBR method is adopted to select satisfying green product design scheme.Thirdly,a case about green product design scheme selection is analyzed.This case is about air condition of a home appliances enterprise,which demonstrates the operation of the method for selecting green product design scheme.The deep research on green product design scheme selection problem not only enrich the related theory research from the perspective of QFD and CBR,but also give a guidance and reference for enterprise to select appropriate green product design scheme.
