Abstract: Aiming at the problem of comprehensive evaluation of multiple decision makers and multi index for dynamic system,the current weighting methods seldom consider the credibility of the decision-makers and the change of target weight with the variation of the evaluation object.A parameter weighting model based on confidence adjustable type S curve index was proposed.Based on the expert scoring method,through introducing expert authority and difference coefficient of experts to determine expert confidence,it enhances the credibility of expert evaluation.An adjustable para-meter is used to calibrate the weighting model based on the confidence index,which can solve the non-linear relation between the evaluation index weight and the dynamic system and increase the flexibility of the weighting model.Combining the results to determine the index weight in accord with the objective reality,it verified the feasibility and practicability of this method,provided a new method for determining the index weight.

Key words: Authority of expert,Expert confidence,Adjustable parameters,S curve of empowerment
