ON MODELING UNCERTAINTY WITH INTERVAL STRUCTURES
S. K. M. Wong, Lei-Xi Wang, Yiyu Y. Yao · Computational Intelligence · 1995
In this paper, we introduce the notion of interval structures in an attempt to establish a unified framework for representing uncertain information. Two views are suggested for the interpretation of an interval structure. A typical example using thecompatibility viewis the rough set model in which the lower and upper approximations form an interval structure. Incidence calculus adopts theallocation viewin which an interval structure is defined by the tightest lower and upper incidence bounds. The relationship between interval structures and interval‐based numeric belief and plausibility functions is also examined. As an application of the proposed model, an algorithm is developed for computing the tightest incidence bounds.
