| As a new research field,argumentation system has important theoretical significance and wide application value.Decision making is usually regarded as a form of behavioral reasoning.Any decision is equivalent to making the best choice among a group of different decision options.In recent years,it is a new method different from the classical decision-making to make decisions with the help of argumentation system,which can better solve the decision-making problems in the complex environment.The multi-attribute decision-making based on argumentation system can be divided into two stages:evaluate the acceptability of decision options and selection of optimal decision options among acceptable decision options.In the previous multi-attribute decision-making based on argumentation system,there is a problem that reasonable decision options are misjudged as unacceptable decision options.In order to solve this problem,this paper defines the relative strength of argument by using the strength of argument and the attack relationship.Using the relative strength of argument,the strength of argument and the attack relation,the new defeat relation is determined.The multi-attribute decision-making based on the set of arguments and the new defeat relation can avoid the situation that the reasonable decision-making options are eliminated,so as to optimize the results of the stage of evaluating the acceptability of decision options.In addition,considering that the decision-making options supported by more powerful arguments are better,this paper defines the strength of the decision options by using the relative strength,and takes the strength of the decision options as a new attribute to participate in multi-attribute decision-making,which can avoid the problem that the final score of decision-making options is higher,so as to optimize the results of the stage of selecting the optimal result for the acceptable decision-making options.Taking the choice of travel mode as an example,we analyze the decision results and find that the improved multi-attribute decision-making results based on argumentation system are more comprehensive,reasonable and persuasive. |
