Effectiveness Evaluation Method for Complicated System Based on Fuzzy Set of Evaluation Index

A method of complicated system effectiveness evaluation based on fuzzy set of evaluation index is proposed. It makes use of fuzzy system evaluation indexes to construct the fuzzy sets,of which the fuzzy membership function is defined by the accessible extent of fuzzy sets. With also the fuzzy analytic hierarchy process,a new method which is especially fit to multilayer system of effectiveness evaluation indexes and complicated system functions is put forward. The results of actual simulation indicate that this method is valuable and effective for system effectiveness evaluation and has great applied prospects.
