Tools for the Development of Macroeconomic Models of the Fuel and Energy Complex

The article describes the software tools used for macroeconomic modeling of the Fuel and Energy Complex. These software tools allow you to generate and modify the relevant macroeconomic models. Its architecture and functional components provide a flexible interaction between the user and the computer simulation system. The software package includes two autonomous subsystems - CREATOR and DIGGER. The CREATOR system is used to create models and change their formal structure. The DIGGER system is intended for the organization of input and editing of data, conducting direct calculations on models, launching optimization procedures. Direct calculations realize the simulation mode of model user. They determine the values of the model indicators according to formulas of the static and dynamic modes. The optimization mode may be used only for multilinear indicators. It is divided into static and dynamic. In the static optimization mode (optimization of one current time circle) non-multilinear indicators are excluded from the optimization task. Dynamic non-multilinear indicators are excluded for the dynamic optimization mode. A direct calculation performed after the optimization procedure completes, it shows whether these indicators satisfy the boundary conditions specified for them. The macroeconomic problems related to the fuel and energy complex that these tools helps to solve online are listed. The capabilities of the described tools are illustrated with a significant example.
