Fuzzy decision making in shape feature design for product development

In this study, a platform for the product shape design is constructed based on fuzzy decision making for shape feature in portable electronic instruments. First, the research summarized shape features of electronic instruments and analyzed rules from the concept of shape grammar. Second, the research utilized fuzzy algorithms, including analyzing the weight of shape features by Fuzzy Analytic Hierarchy Process (FAHP), exploring the relationship between customer demand in shape features and rules of shape grammar (technical requirements) by Fuzzy Quality Functional Deployment (FQFD), estimating the inferential results by the Fuzzy Synthetic Evaluation Model (FSEM) that made the decision making platform was built considerately for a pressure meter. Flash ActionScript was used as the programming tool for building the platform in shape feature design. Two portable pressure meters are proposed compared with the existed meter as the implementation for proving the research process.
