Abstract: To make full consideration of product conceptual design's scheme evaluation and decision on the demand preferences of customers and to further enhance customer satisfaction during the products innovation process,an evaluation and decision method based on customer clustering analysis was proposed.Based on the analysis of customers' demand preferences,the process of similar demand preferences customers clustering was constructed by using graph theory with output of undirected connected sub-graph.By considering the contradictions between the product innovation design scale and design costs,the evaluation criteria of customer clustering was established to obtain the optimal clustering results.The evaluation and decision of the optimal product conceptual design schemes corresponded to each customer clustering were realized by combining with the dominance analysis-based design schemes sorting method.Fast clustering of new customers and recommending process of its product design requirements were considered.A refrigerator innovation conceptual design scheme evaluation example was given to verify the feasibility and effectiveness of proposed method.
