For the application of economic and mathematical methods in practical activities in modern conditions, material, scientific and personnel prerequisites have been created. Their use makes it possible to carry out complex and very time-consuming calculations that were previously impossible. The article considers economic and mathematical methods, features of their application in agricultural organizations. Taking into account the production and technological parameters, the conditions of a particular agricultural organization, a model was developed and a methodology for solving the problem of optimizing the feed ration of farm animals was developed, including four groups of restrictions: on the balance of nutrients; by dry matter content; by the content of trace elements and vitamins; by the specific weight of food groups in the diet. The target function is the minimum cost of the daily ration. The introduction of an optimal diet will significantly reduce the cost of feed, and, consequently, the cost of production. We also algorithmize the issue of feed ration for livestock using economic mathematical modeling. Let's write the program code using the Python programming language using the built-in algorithm.
Instead of the traditional 'system-environment' pair for objects of the regional economy, it is proposed to consider metasystems - these objects together with all interacting objects of the microenvironment. E...

The aim of this work is to derive a symbol calculus on L2(Rn) for multidimensional Hausdorff operators. Two aspects of this activity result in two almost independent parts. While throughout the perturbation matrices a...

We show that under an arithmetic condition the spectrum of a bounded multidimensional discrete Hausdorff operator in the Lebesgue space is an annulus (or a disc) centered at the origin, provided the perturbation matri...
