In this paper a fuzzy-comprehensive-evaluation-based multi-level decision method for machine tool selection is put forward, and the fuzzy synthesis models for primary and final selection of machine tools are established. The ascertaining methods of membership functions are discussed in detail. An example is used to illustrate the applications of the decision methods. The decision courses is effectively minished by a multi-level selecting method. The expression method of knowledge by rules is replaced by a fuzzy mapping method, and the expression efficiency is improved. In CAPP system the multi-level decision method for machine tool selection based on fuzzy comprehensive evaluation is a banausic method .
