Discussion of the design philosophy and modified non-expert fuzzy set model for better product design

The research discusses the design philosophy for product development. It emphasizes the importance of independent evaluation with non-expert knowledge base in a commercial product design. To resolve the issues with the raised design philosophy, a fuzzy mathematic model with modified Hamming distance fuzzy set method is proposed to conduct such a non-expert evaluation for achieving better product design in industrial practices. This modified fuzzy model is able to coordinate and to deal with the tangled fuzzy and non-fuzzy issues involved in the product design to carry out a comprehensive and effective non-expert evaluation. With the model, a simple and effective tool can be built for engineers to conduct sophisticated product design.
