Investigation of the “Input-Output” Model of the Azerbaijani Economy in Interval Information Conditions

Abstract

In the proposed research study, Azerbaijan economy is analyzed by using the interval analysis method. The purpose of this article is to apply the method chosen by the method of interval direct expenditure coefficient matrix A $\in \left[ {A_{min} ,\,A_{max} } \right]$ to study the method of solution of the linear problem and to have a high computation of practical computation efficiency.

In the article by the method of Leontief’s “Input-output” model interval analysis, the uncertainty of the parameters of the direct expenditure coefficient matrix A $\in \left[ {A_{min} ,\,A_{max} } \right]$, the total volume of product vector X $\in \left[ {X_{min} ,\,X_{max} } \right]$ and the output vector $Y \in \left[ {Y_{min} ,\,Y_{max} } \right]$ are described only as boundaries of possible values. The results of the researches show that, during the traditional interval estimates, the result range is usually great, and this reduces the importance of the answers. For this purpose, special methods have been developed to reduce the difference in result values.
