Title Multi-criteria decision making method based on prospect theory
Abstract In this paper, a hybrid criteria decision making method has been proposed。 Firstly, explain the background and the importance of the research, meanwhile, settle the direction of this paper which is based on prospect theory and hybrid criteria。 Then, briefly introduce the knowledge of prospect theory and multi-criteria decision making methods。 Next, present ways of dealing with the hybrid numbers that are chosen to be the value of this essay, also introduce the method of sorting data。 What’s more, the median value is chosen to be the reference point, also, the value of distance between reference point and attributes serves as value of the function。 In order to maximizing the prospect value, a linear matrix has been built to calculate the probability weight of each criteria。 Acquiring the value and weight of each attributes, the comprehensive value can be computed and the best solution will be found。 In the end, an exact example shows the effectiveness of this method。
