A Fuzzy DEA/AR Method for Manufacturing Mode Selection

In order to guarantee manufacturing enterprise to choose the most effective manufacturing mode it’s essential to evaluate relative effectiveness of manufacturing mode of manufacturing system. A fuzzy data envelopment analysis/assurance region evaluation method is proposed. Assurance region prevents input and output parameters from being ignored or interdependent in excess during the process of evaluating manufacturing modes. Triangular fuzzy number is adopted to represent uncertain input and output parameters of complex manufacturing system. By introducing cuts to calculate upper and lower bound of fuzzy effectiveness of manufacturing mode. Ranking method based on fuzzy effectiveness bound is provided to determine the manufacturing mode with the optimal relative performance. An example demonstrates the validity of proposed method.
