It is well known, that matrices play major role in various areas such as science, engineering
and technology, social sciences and many others. In real life, due to the inevitable …

The purpose of this article is to put the concept of interval linear algebra on a sound
algebraic setting, by judiciously defining a Field and a Vector Space over a field involving …

Optimization processes in mathematics, computer science, and economics solve problems
effectively by selecting the best element from a set of available alternatives. One of the most …

Generally, vagueness is modelled by a fuzzy approach and randomness by a stochastic
approach. But in some cases, a decision maker may prefer using interval numbers as …

This paper attempts to resolve the problem concerning the interval observers design for
linear systems with ostensible Metzler system matrices. Because system dynamics matrices …

Finding the simplest form of a set of quantities is an important aspect of any branch of
Mathematics. Of course, the simplest form or the canonical form as we often call it in …

In this paper, we introduce the concept of Moore-Penrose inverse of a rectangular interval
matrix based on a modified interval arithmetic. We determine the Moore-Penrose inverse in …

The fixed charge transportation problem (FCTP) is a variant of the well-known transportation
problem in which the price of conveying products from a source to a sink is made up of a set …

In this paper, we discussed single variable unconstrained optimization techniques using
Interval Analysis. The most of the unconstrained linear problems have been dealt with …
