Evaluation Method for Conceptual Design Scheme Based on Fuzzy Mathematics
Selecting the favorable conceptual design scheme is the first step to make a new product development (NPD) successfully.To guarantee reliability and rationality of decision-making about multiple design schemes in conceptual design stage under the impact of uncertainties and qualitative information,we have employed KJ method to cluster the evaluation factors into 5clusters such as emotion,ergonomics,aesthetics,core technology,and impact; and fuzzy mathematics method to deal with uncertainties and qualitative information effectively.The weights of evaluation factors were calculated by analytical hierarchy process (AHP).Fuzzy mathematics method is the comprehensive evaluation method and quantitative analysis which based on the maximum membership degree evaluation.All design schemes are ranked and selected according to the multiple evaluation score of parts with their weights.Finally,a case study for decision-making is presented to demonstrate the application of the evaluation method.
