Study of Machine Tool Selection Based on Fuzzy Comprehensive Evaluation

For multivariate and fuzziness of machine tool selection in CAPP system, fuzzy comprehensive evaluation has been proposed based on analytic hierarchy process. Fuzzy evaluating model system has been built. Through the synthetic analysis of the factors which influence on machine tool selection, fuzzy relation between the effecting factors is set up. Multivariate quantitative problems were solved well, and the uniqueness of machine tool selection is ensured. This method solved the problem of machine tool selection better and ensured the reliability & availability by running on the prototype system.
