Research on Improved Multiple Attribute Variable Weight Decision Making Based on Optimistic Coefficient Method

The method of updating weights using the fixed weight vector in the multi-attribute variable weight decision cannot effectively describe the weights' variation when the state vector is continuously changing. To solve this problem, an iterative weight updating method is proposed. Based on the existing optimistic coefficient method, the influence of high-order terms is discussed, updating weights with the fixed weight vector and updating weights with iteration.
