The method of combining subjective with objective weight in multiple objective decisions

Setting index weight is important in multiple objective decisions. Many weight making methods have been put forward. These methods are divided into subjective weight methods and objective weight methods. Each method has its advantages and disadvantages. This paper combines the subjective weight with objective weigh methods to make decisions. The subjective weight uses the scale extending of AHP. The objective weight adopts Entropy Weight Coefficient method. Numerical simulation demonstrates the effectiveness of combining subjective weight with objective weight is better than only using subjective weight.
