119 The Combined Weighting Model Based on Maximizing Deviations in the Multiple Attribute Decision Making

There are some kinds of methods to determine attribute weights in the multiple attribute decision making. In fact, each method has its own advantages and disadvantages. An optimal combined weighting model is proposed by maximizing deviations in order to make full use of the information contained in these methods. We also discuss the solution to the optimal combined weighting model. Finally, an example illustrated to evaluate the effectiveness of electric vehicles and conventional vehicles from the perspectives of environment, social, economic, and health factors.
