Research and Application of ELECTRE Ⅲ Method Based on Preference in Probabilistic Uncertain Environment
For the multi-attribute group decision making(MAGDM)problem in probabilis-tic uncertain language environment,in order to better reflect the preference degree of mul-tiple experts'evaluation information for different attributes,this paper innovatively con-structs a new attribute preference relationship.Considering the difference degree of expert evaluation information,the concept and calculation method of difference degree are put forward.Firstly,the evaluation information of multiple experts is summarized,and the preference degree of all experts for each attribute is obtained by calculating the difference degree between different schemes and different attributes.Secondly,this paper studies the ELECTRE Ⅲ method of multi-attribute group decision making in probabilistic uncertain language environment.By calculating the consistency index and inconsistency index be-tween schemes,the hierarchical priority relationship between schemes is constructed,and then the alternative schemes are comprehensively ranked.Finally,the applicability and feasibility of the ELECTRE Ⅲ method in the environment of probabilistic uncertain language is verified through the example analysis of supplier selection of green supply chain and the comparison analysis of other methods in the environment of probabilistic uncertainty.
