中文摘要：
现实世界中的区域多具有不确定边界,现有基于确定区域的建模方法无法直接处理此类不确定区域间的方向关系.用宽边界表示区域的不确定边界,以区域的最小边界矩形（minimum bounding rectangle,简称MBR）为模型,提出一种基于MBR的不确定区域间方向关系建模方法.利用基于MBR的主方向关系和矩形代数表示不确定区域间方向关系;定义不确定区域间方向关系的相容性复合;并给出一种相容性复合计算方法.
英文摘要：
Most regions in real world have uncertain boundaries.The present models based on crisp regions can not deal with the Direction Relations between the Regions with Uncertain Boundaries（DRRUB）.Using broad boundary to represent the uncertain boundary,a novel approach based on the model of MBR（minimum bounding rectangle）is proposed for modeling DRRUB.In this paper,DRRUB are described by MBR-based cardinal direction relations and rectangle algebra,then we study the consistency-based composition of DRRUB,and a method is put forward for calculating this consistency-based composition.
