Evaluation method of online knowledge paid products based on an improved interval-valued intuitionistic fuzzy multi-attribute group decision making
To address the evaluation and selection problem of online knowledge payment products,the evaluation attributes from two dimensions of knowledge payment products and knowledge producers were designed,and an improved interval-valued intuitionistic fuzzy multi-attribute group decision making method was proposed.The decision maker weights of each attribute were determined by considering the expertise of decision makers;a consensus reaching model based on information and knowl-edge exchange was constructed so that critical decision information and knowledge would not be modified;then,a value func-tion of improved prospect theory was used to more accurately portray the psychological preferences of decision makers.A case study was used to verify the effectiveness of the proposed method,and the innovative nature of the proposed method was con-firmed by a comparative analysis with existing decision-making methods.This paper not only provided new research ideas for studying online knowledge payment products from the perspective of product quality evaluation,but also helped online knowl-edge payment platforms to evaluate online knowledge payment products,and then urged knowledge producers to improve prod-uct quality.
