Fuzzy Comprehensive Evaluation for Reconfigurable Assembly Line

On the basis of the analyzing of the criterion of the evaluation index, a comprehensive evaluation model for RAL (reconfigurable assembly line) is proposed based on the hierarchy analysis according to the characteristics of the RAL and the engineering application. The new combination weighting method is used to calculate the weights of every index, and the index is assessed by fuzzy synthetically evaluation. The subordinate degree of evaluation object relative to optimum reference value adopting least squares principle is regarded as the evaluation criteria. Finally, this method is demonstrated to be reasonable and effective by a simulation example.
