本文研究了用逻辑的方法描述偏好的问题，并使之应用于基于逻辑描述的冲实分析方法中去。偏好模型的好坏是冲突分析方法实用与否的关键。基于逻辑的模型化方法就是用形式化逻辑的方法作为工具来解决相关的管理科学问题，基于逻辑模型的偏好结构．提供了一种新的偏好模型化方法，为构造冲突分析决策支持系统提供了一种有用的工具。 This paper studies the problem of describing preferences in a logical way and applies it to the flushing analysis method based on logical description. The quality of the preference model is the key to the practicality of the conflict analysis method. Logic-based modeling approach is to use the formal logic method as a tool to solve the related management science problems, based on the preferred structure of the logical model. A new preference modeling method is provided, which provides a useful tool for the construction of conflict analysis decision support system.
