Abstract: To solve the problems faced by the evaluation of product concept schemes in the design crowdsourcing model,such as the large number of schemes,poor rationality of evaluation index system,weak interpretability of index weight,and difficulties in integrating certain and uncertain information,a new product concept evaluation method for design crowdsourcing was proposed.The key process and implementation steps of the method were explained,including preliminary screening of schemes based on feature recognition and expert judgment,selection of evaluation index based on the $APPEALS model,initial determination of index weights based on DEMATEL method,adjustment of index weights based on KANO model and comprehensive integration of evaluation information based on evidence reasoning.Compared with other methods,the key factors of product success,the mutual influence between evaluation indexes,the user's voice in schemes selection and the integration of certain and uncertain information were better considered.The proposed evaluation model was analyzed by combining with the crowdsourcing case on the Design Boom crowdsourcing platform,and the reliability and validity were verified.
