ABSTRACT
The United States Navy has currently mandated that Set-Based Design will be used as its preferred design method for all its future design activities. With this need in mind, the expansion of a previously developed Set-Based Design facilitation and negotiation method is presented. The original work demonstrated the ability to utilize expert opinion, in the preliminary design stage, as a means to successfully execute a Set-Based Design activity. However, the existing model focuses only on technical feasibility. This paper proposes an improved model through the addition of performance evaluation into the fuzzy logic method.
The extended method utilizes fuzzy logic state space mapping in conjunction with fuzzy logic controllers to enable the modification of design convergence so that factors such as production risk and development risk can be taken into account. The mathematical formulation of the methods as well as a design study is presented to demonstrate the research.
