| 以定性偏好描述语言LPD(logic preference description)为基础,提出把定性偏好表示为基于命题逻辑的逻辑链,主要工作包括:(1)提出一个带有偏好的决策过程的一般性框架,在此框架内,详细介绍了LPD偏好描述语言;(2)提出基于LPD偏好算子的逻辑链构造方法.从而把LPD语言中偏好推理转化为相应的逻辑链构造过程,便于偏好重用.最后总结全文并提出需要进一步研究解决的问题. |

| Abstract: |
| In this paper, logical chain is introduced to be the uniform preference representation mean in iterative reasoning of qualitative preference description language LPD (logic preference description). The main contributions include: (1) A new general framework of several common decision making settings is proposed, and LPD is introduced in the framework; (2) LPD is translated into logical chains by constructing logical chains instead of preference operators. Consequently, the preference reasoning in LPD is reduced to several methods of constructing logical chains so that the complex preferences in LPD can be reused in subsequent handlings. Moreover, the conclusion and the prospective are presented in the end. |
