Multi-Objective Fuzzy Optimization Design for Clamping Mechanisms of Injection Machines

A mathematical model for multi-objective optimization is proposed, in which the magnification ratio of force, the stroke ratio, and the frequency of idle cyele, are employed as objective functions. Penalty function technique with calling POWELL method is performed. By use of fuzzy similar priority ratio method, the optimal solution could be found among those non-inferior solutions, which is closest to the ideal solution.
