Integrated Product Design through Multi-Objective Optimization Incorporated with Meta-Modeling Technique

Associated with the design of a value system having inherently multi-attributed nature, this paper describes an integrated multi-objective optimization incorporated with meta-modeling. It aims eventually at developing a user-adaptive system toward flexible integrated product optimization of articraft. From this viewpoint, we present a design method for multi-objective optimization (MOP) in terms of computational intelligence. The method is very flexible in identifying a value function that is likely to fluctuate depending on the decision environment. The method is proven to be robust against unsteady and unstable human subjective judgement, and amenable to the problem using meta-model for emerging technologies. To facilitate its wide application in various areas and in multi-disciplinary decision environment, we implement it on an Excel spreadsheet. The usefulness of the developed software is examined through an illustrative study regarding the design of a micro devise.
