The Research Of Hesitant Fuzzy Linguistic Multi-attribute Decision Making Based On The Psychological Behavior

In real life,because of the complexity of the decision-making problem,decision-makers' limited cognitive structure,realistic problem of fuzziness,decision-makers decision-making information forms of diversity,"irrational" of the decision-makers themselves,as well as the limitations to obtain all information and to continuous improvement.It is very necessary to improve and develop the decision-making theory.The current policymakers multiple attribute decision making method limit that decision-makers are all "completely rational," while less consider the person's psychology behavior characteristics impact on the result of the decision.Therefore,this paper systematically study the psychological behavior of the decision makers of multiple attribute decision making based on the premise of the hesitate fuzzy nature of language.This paper conducts depth study from the following four aspects:Firstly,this paper research the hesitant fuzzy language numbers' nature from two angles: the number of hesitant fuzzy language distance measure and the algorithm.Based on the traditional distance measure,itr introduces hesitancy degree to depict the decision makers of hesitation.meanwhile,according to the characteristics of the hesitant fuzzy language number,improves the operation rule of the hesitant fuzzy language number,solved the existing several problems in the operation of hesitant fuzzy language.further,put forward the hesitant fuzzy language method to determine the attribute weights of maximizing deviations hesitated fuzzy number based on the research of hesitant fuzzy number's nature.Secondly,on account of the psychological behavior characteristics that decision makers lean to consider of loss aversion,this paper puts forward the hesitant fuzzy language for multiple attribute decision making method based on the prospect theory.It proves the combination of the probability weighting function of prospect theory and fuzzy language has certain internal mechanism and the important significance.Also it shows that the description and decision-making information which introduces the hesitant fuzzy language number into foreground function as attribute is rational.Thirdly,on account of the psychological behavior characteristics that decision makers lean to consider of loss aversion,this paper puts forward the hesitant fuzzy language for multiple attribute decision making method based on the regret theory.Combining the deductive logic of regret theory and hesitation combination of fuzzy language,this paper uses the hesitant fuzzy language for characterizing attribute values to express decision makers' regret aversion and hesitation in decision-makingFinally,through the case study of film score method,provides the more realistic background for the research question,at the same time,it can prove the rationality and feasibility of the hesitant fuzzy linguistic multiple attribute decision making method based on the prospect theory and the hesitant fuzzy linguistic multiple attribute decision making method based on the regret theory.Meanwhile,this paper tries to provide some theoretical reference and practical significance for optimization of film scoring system.
