Estimation of the United Solution Set of an Interval Leontjev's Model

K. F. Ivanova , e-mail: klara.i2010@yandex.ru

The approach to the solution of a modelling V. V. Leontjev's problem described by interval system of linear equations (ISLAE) on the basis of application of a "sign" technique is offered. Intervals for total a component of a branch facilities as result of a special case of the solution of two point linear algebraic systems with positive square matrixes and with correct intervals of an interval right-hand side vector are received. The estimation of the united solution set with observance principle of the universality, previous to a principle of the existence, having a place at construction of an internal solution ISLAE is realized.

Keywords: interval system of the equations, estimation of the tolerable solution set, "sign" technique, two point linear systems.
