The article is devoted to elaboration and construction of a static model of macroeconomics in which economics is considered as an unstructured holistic unit, the input of which receives the resources, and the output is the result of the functioning of economics in the form of gross domestic product or gross regional product. Resources are considered as arguments, and gross output--as function. Simulation is carried out using the production function for Russian Federation in general and for its eighty-three regions and eight federal districts. For building the models there were selected such macroeconomic indicators as gross regional product, value of fixed production assets, population, number of people employed in the economy, number of economically active population. For each region the model was built in current and comparable prices, with and without allowance for technological progress. Macroeconomic models used statistical data for 15 years (2000-2014) and the number of built models is 2208. The appropriate software "EGRMod" was engineered to work under Windows operating systems using MS Access or under control of Access Runtime library. External Access database is used to collect data. Numerical calculations are performed in SQL language using VBA.
