一种基于辩论的决策方法研究

为了解决动态开放环境下决策方案可行性论证的难题,将辩论理论与实用推理结合提出了一种新的适用于多属性决策的辩论框架,定义了论据的类型和论据之间可能存在的攻击关系。将基于辩论的多属性决策过程分为用户需求获取、方案可行性论证和可行方案选优3个阶段,通过论据及其攻击关系对方案的可行性进行辩论论证。最后采用一个医疗决策问题对该框架的应用进行了示例说明,结果表明,该框架能够较好的处理信息不完整、不一致条件下的决策问题。

An argumentation-based approach for decision making

In order to determine the feasibility of the candidate solutions of a decision problem in the dynamic and open environments,a new argumentation framework for multiple attribute decision making based on the argumentation theory and practical reasoning was proposed.The types of arguments and attack relation between them were defined.The argumentation-based multiple attribute decision making follows three steps:the acquisition of decision maker’s requirements,justification of the feasibility of the candidate solutions and the ordering of the feasible candidate solutions.The justification of the feasibility of the candidate solutions is based on the arguments and the attack relation between them.Lastly we adopt a medical decision making problem to demonstrate how to use the argumentation framework.The result indicates that the framework is suitable for decision making in context where information is incomplete and inconsistent.
