基于限制优势关系的集对粗糙决策分析模型

在不完备偏好信息系统中，目前已有多种扩充，如基于扩展优势关系、基于广义扩展优势关系、基于限制优势关系等扩充，但这些扩充都存在各自的局限性。针对这些局限性，本文采用集对分析方法，定义集对 近似限制优势关系概念，提出一种基于限制优势关系的集对粗糙决策分析模型。这种模型是基于限制优势关系的集对粗糙决策分析模型的扩充和改进。该模型通过近似程度 的调节和控制，保证这种限制优势关系划分的准确性，同时更具灵活性，更适合处理大型不完备偏好信息系统。

Set-pair Rough Analysis Model of Multi-attribute Decision Making Based On Linminted Dominance restriction

Now there were several extensions in the Incomplete preference information system, such as ,based on extended dominance relation, based on generalized extended dominance relation, based limited dominance relations. Unfortunately, these extensions were present their own limitations. In this paper, set-pair almost limited dominance restriction was defined by introducing Set-pair Analysis ideas. A new extension of rough decision analysis model based on set-pair almost limited dominance restriction was presented. This model not only didn't the extension reserve the advantage of limited dominance relation, but also its flexibility had been increased by adjusting the value of the almosty while its accuracy was also guaranteed. This model is suited to deal with large incomplete preference information system.
