Abstract:

Whether the application of the theory and method of multi-criteria decision making can achieve the expected economic and social benefits has gradually become the core issue in this research field. In recent years, the theory and method of decision making based on Probabilistic Language Term Set（PLTS） has attracted much attention, PLTS can not only reflect decision maker’s hesitant fuzzy language evaluation or preference to the scheme or criteria, but also reflect the probability information of each linguistic term, which is close to decision-makers’ cognitive process. It has been widely used in investment project risk assessment, pattern recognition, medical diagnosis and other fields, and has produced good application effect. The research status of PLTS is reviewed systematically from four aspects：information fusion theory, measure theory, preference relation theory and multi-criteria decision method based on PLTS, the shortcomings of existing research are analyzed. It is indicated that Probabilistic Uncertain Linguistic Term Set（PULTS） can reflect the fuzzy uncertainty of qualitative decision information more efficiently and accurately. The follow-up research in this field should focus on the core issues such as the information fusion of PULTS, the framework of measurement theory, the consensus-consensus process of preference relations, the multi-criteria group decision making method and its application research, corresponding research ideas are given to provide a feasible reference for the follow-up research in this field.
