| 摘 要： | 为了处理重要的Jrv类粗糙Vague区域关系,基于Vague集和粗糙集的联合给出Jrv类粗糙Vague区域关系的数学模型表示.通过分析粗糙Vague区域关系模型的复杂粗糙变换情况,确定粗糙Vague区域关系的动态关联邻接图.基于粗糙Vague区域的上﹑下近似模型,提出Jrv类粗糙Vague原子区域关系的可能蕴涵情况表,基于蕴涵情况表给出Jrv类粗糙Vague区域关系的可能蕴涵式.给出实例模型,并对实例模型进行分析.理论研究和实例分析结果表明,该模型可以处理复杂的Jrv类粗糙Vague区域关系,极大地增强了空间数据库处理复杂不确定区域关系的能力.

| Abstract: | The mathematic model representation of Jrv rough Vague region relation was given based on Vague set and rough set in order to deal with the important Jrv rough Vague region relation.The dynamic relevance adjacency graph of rough Vague region relation was determined through analyzing the complex rough-transform situation of the rough Vague region relation.The possible implication expression table was proposed based on the upper approximation and lower approximation of the rough Vague region.The possible implication expression of the Jrv rough Vague region relation was given.The analysis of an instance was discussed.Results show that the model can greatly enhance the ability of the spatial database for the complex uncertain region relation. |
