This study proposes a robust design method for adjustable mechanisms, such as seat reclining mechanism, and a supporting system assisting the product development using a variety of robust design methods. Specifically, the proposed method derives the optimum (minimum) adjustable range of design parameters, required to set the varied objective characteristic values, calculated by the Monte Carlo method, into the tolerance, using Genetic algorithm. The supporting system includes the classification scheme of robust design methods based on the features of the objective function and parameters in order to properly choose a robust design method.
