To control influence of subjective evaluation on evaluation,based on three-point interval number,the aim of this paper was mainly to define the expected value by the introduction of decision-making factor,and propose a changeable weight fuzzy comprehensive evaluation model.

Aiming at the low accuracy of fault diagnosis when the weight of fault symptoms is varying with the fault types in complex systems,the author proposes a new concept of varying weight model of fuzzy comprehensive evaluation.

With the introduction of comprehensive weight variation fuzzy evaluation into performance evaluation of Automatic Target Recognition (ATR), an open performance evaluation model is established.

Application of varied weight evaluating model for synthetical management benefits assessing;

This paper achieves decision-making of bidding by using the theory of fuzzy mathematics to establish a fuzzy comprehensive evaluation model.

Establishing a fuzzy comprehensive evaluation model,the paper tries to builds up a workable risk evaluation model in or- der to evaluate the risk of supply chain partnership and checks the practicability and workability of the model with a case.

A model of multistage fuzzy comprehensive evaluation for unloading high-steep slope stability analysis has been established.
