Abstract: The importance ratings of technical characteristics(TCs)of electric vehicle,which can help optimize the distribution of resources and fulfill customer requirements(CRs),play a key role in the research and development of electric vehicles.In consideration of the CRs,the performances of competing products,the availability of technologies,and the comprehensive strength of enterprises,this paper put forward a model for the determination of the importance ratings of TCs based on quality function deployment(QFD)under uncertain context to offer a scientific and effective product development tool for electric vehicle manufacturers.In the model,the basic uncertain linguistic information(BULI)is introduced to characterize uncertain information.The main steps include:identify CRs and determine the importance ratings of CRs using best worst method(BWM);determine the relationship level between CRs and TCs and then obtain the basic importance ratings of TCs;utilized BWM to determine the modified importance ratings when considering the analysis of competing products,the availability of technologies,and the comprehensive strength of enterprises;integrate basic importance ratings and modified importance ratings and acquire the comprehensive importance ratings of TCs.Finally,the feasibility and effectivity of the model is illustrated by the case of the electric vehicle development.
