Fuzzy evaluation based on entropy weight for multi-sensor judgment of operating mode
Yang Cheng-wu · Industrial Instrumentation & Automation · 2006
In order to overcome the subjective limitation in traditional fuzzy comprehensive evaluation,the weight value is modified based on the differential degree of evaluation indices,a new model for comprehensive evaluation——entropy weight comprehensive evaluation model is established by using the concept of in information engineering science.And the model is applied to the multi-sensor judgment of operating mode.This paper analyzes all kinds of factors which influence the multi-sensor judgment of operating mode.From the view of fuzziness on evaluation,rational analysis and discussion in theory are carried out for each factor by means of principle and way on fuzzy mathematics.The weight of factor is calculated objectively by the method of entropy weight coefficient,not only by subjective judgment.And the inherent information of the evaluated subject is used to a full degree.So the drawback of the traditional evaluation can be avoided that only a few indicators of process are emphasized while others are out of consideration.Thus the model is more effective and feasible.
