In practice, it is important to describe such an inclusion set by finitely many numbers, and it seems profitable to use intervals of a partially ordered domain (interval arithmetic). In this paper, some mathematical concepts and methods are considered in this way, and some applications are given.}, identifier = {03848504}, }
