【摘要】 本文提出了组合区间结构的一种方法．该方法先是用乘积空间来表示新的证据空间，然后组合各个子空间结构在同一乘积空间上的柱面扩张．为了解释区间结构组合的合理性，本文用信息源的析取组合方法与该组合方法进行了比较，并证明了在合理的情况下这两种组合方式是一样的．更多还原

【Abstract】 This paper provides a method of the combination of interval structures.In order to obtain a combination of interval structures, it first uses the product space to represent the new evidence space, then composes the cylindrical extensions of the interval structures of subspaces, and combines the cylindrical extensions on the same product space. In this paper, the disjunctive combination of information sources is compared with the authors’ combination method, and it is proved that the combination method is equal to the disjunctive combination under a reasonable case.更多还原
