摘要

在这项工作中,研究的对象是该地区的经济。为了描述它,提出了一种构造差分输入输出动态模型的规则方法。这种方法不仅包括对生产领域的建模,还包括对消费领域的建模。为此,相位变量的向量包括国内生产总值。模型的可变性在于考虑到各种宏观经济参数的能力,这取决于分析和控制宏观经济趋势的最终目标。研究表明,在经济各部门直接投资的情况下,经济的动态可以用线性控制的差分系统来描述。如果需要考虑增加模型对管理影响敏感性的其他宏观经济参数,则会导致各种类型的非线性差异系统。在文章的最后一部分,描述了投资项目开发的情景方法。该方法基于构造程序控制和稳定受控差分系统的相应程序运动的原理。

Difference dynamic input-output models
In this work, the object of study is the economy of the region. To describe it, a regular method for constructing difference input - output dynamic models is proposed. This approach involves modeling not only the sphere of production, but also the sphere of consumption. To do this, the vector of phase variables includes the gross domestic product. The variability of the model consists in the ability to take into account various macroeconomic parameters depending on the ultimate goals of analysis and control of macroeconomic trends. It is shown that the dynamics of the economy with direct investment in various sectors of the economy is described by linear controlled difference systems. If there is a need to take into account other macroeconomic parameters that increase the sensitivity of the model to managerial influences, then this leads to nonlinear difference systems of various types. In the final part of the article, a scenario approach for the development of investment projects is described. This approach is based on the principles of constructing program controls and stabilizing the corresponding program movements of a controlled difference system.
