Innovative design approach for product design based on TRIZ, AD, fuzzy and Grey relational analysis

摘要

Innovation and efficiency in concept design are essential to the competitive development of a new product. But various complex problems will appear during the early stage of concept design. If these problems are to be effectively resolved, a new synergistic approach based on AD, TRIZ, Fuzzy and Grey Relational Analysis, needs to be incorporated into concept design. This new approach should exploit TRIZ tools more effectively and should complement AD in the specification of design parameters while decoupling the coupled design matrix. Forecasting tools should be employed to identify the correct design goal and further decompose function requirements. In addition, uniformity between the hierarchies of FRs and DPs in AD should be checked to find and eliminate potential conflicts. In addition, the powerful evaluation method of the Grey-Fuzzy Information Axiom should be adopted to deal with multiple attributes and complicated alternatives in the framework. The feasibility of the proposed approach will be demonstrated through two case studies in manufacture and chemistry industries, which have been shown to be effectively applied to concept design during the solving of complex problems.
