The comparison of intervals, following several order relations, is relevant in interval linear programming methods to solve many real-life problems.

Abstract
The comparison of intervals, following several order relations, is relevant in interval linear programming methods to solve many real-life problems. The determination of coefcients as crisp values is practically impossible in reality, where data sources are often uncertain, vague and incomplete. The uncertainty can be modelled with coefcients that vary in intervals, making possible a decision making process that is common in the areas of soft sciences like social science, economics, nance and management studies. To help comparison of intervals according to different relevant order relations, a general comparison index is proposed and some properties are illustrated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
