Method of Determining Index Weight in Helicopters General Quality Characteristics Evaluation based on Information Entropy
Weight reflects the essentiality of an index in general quality characteristics evaluation,and it is the key problem in helicopters general quality characteristics evaluation.A method of deter-mining index weight in helicopters general quality characteristics evaluation based on information en-tropy was presented.The index weight evaluation matrix was established based on collection of ex-perts'opinion,the entropy weight and discrimination of experts'evaluate were calculated,and then the discrimination was translated to the reliability factor.The index weight was subjective and objec-tive determined by amendment of reliability factor.It put forwarded a new method to determine index weight in helicopters general quality characteristics evaluation.
