ON ARITHMETIC OPERATIONS OF INTERVAL NUMBERS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2005
In this paper, by using Sengupta and Pal's method of comparison of interval numbers and a new set of arithmetic operations for interval numbers, we propose a theory for the study of arithmetic operations on interval numbers.

On the interval number of special graphs

Journal of Graph Theory, 2004
AbstractThe interval number of a graph G is the least natural number t such that G is the intersection graph of sets, each of which is the union of at most t intervals, denoted by i(G). Griggs and West showed that $i(G)\le \lceil {1\over 2} (d+1)\rceil $. We describe the extremal graphs for that inequality when d is even.

On Interval Fuzzy Numbers

2011 Workshop-School on Theoretical Computer Science, 2011
Interval fuzzy sets allow us to deal not only with vagueness (lack of sharp class boundaries), but also with uncertainty (lack of information). The aim of this tutorial is to present some basic concepts about interval fuzzy numbers. Several concepts related to fuzzy sets are extended to the interval approach.

The interval logarithmic number system

16th IEEE Symposium on Computer Arithmetic, 2003. Proceedings., 2004
We introduce the interval logarithmic number system (ILNS), in which the logarithmic number system (LNS) is used as the underlying number system for interval arithmetic. The basic operations in ILNS are introduced and an efficient method for performing ILNS addition and subtraction is presented.

On the Interval Number of a Triangulated Graph

Journal of Graph Theory, 1987
AbstractThe interval number of a simple undirected graph G, denoted i(G), is the least nonnegative integer r for which we can assign to each vertex in G a collection of at most r intervals on the real line such that two distinct vertices v and w of G are adjacent if and only if some interval for v intersects some interval for w.
