A Novel Fuzzy Comprehensive Evaluation Method for Product Configuration Design Integrated Customer Requirements

Product configuration design is the core of mass customization. In the process of product configuration design, the configuration schemes obtained according to the customer requirements may have many, but scientifically and effectively selecting the best result from them needs the reasonable evaluation. This paper takes the clear customer requirements as part of the evaluation indexes into the evaluation system, and a novel fuzzy comprehensive evaluation method for configuration scheme integrated customer requirements is proposed by using the fuzzy set theory. This method takes the customer as the evaluation subject, and the maximum comprehensive satisfaction for the customer is the final evaluation target. The explicit customer requirements, the technical characteristics, economic characteristics and social characteristics of the product take as the specific evaluation indexes. The weights of customer requirements are determined with the standard weight matrix method and normalized as corresponding weights of evaluation indexes; in addition, the weights of other evaluation indexes are determined by using analytic hierarchy process (AHP) to construct the judgment matrix for sequencing and optimizing configuration scheme. Finally, a money-binding machine is taken as an example to validate the effectivity of proposed method.
