A Direct Method for Determining a P-Solution of Linear Parametric Systems

Abstract

Kolev L

Recently, a new type of solution to a linear interval parametric (LIP) system (called parameterized or p-solution) has been introduced. An iterative method for determining such a solution has also been proposed. In the present paper, a direct method for determining the p-solution is suggested. Its functional characteristics are compared with those of: (i) a direct method for computing an outer interval (nonparametric) solution of LIP systems, (ii) the known iterative method.
