description: The subject of the graduate qualification work is "Construction of mathematical models for forecasting the volume of payments in power supply companies". The given work is devoted to the analysis and forecasting of a time series comprising information on the amounts of payments made by customers of a power supply company. The research set the following goals:1. Explore existing solutions for time series forecasting;2. Implement existing solutions in order to choose the best model;3. Choose a model and solve problems with peaks;4. Integrate solutions into a client-server application for forecasting the volume of payments of a power supply company.The work was done based on data received from the power supply company for 10 years (01.01.2012 â 11.24.2021).6 different mathematical models were selected and studied. Each of them was implemented in Python. For most, the window method was used. The problem with peaks was solved by separating the "peak" dates and making a prediction for them.As a result of the research, a mathematical model of the least squares support vector machine (LSSVR) was selected after comparing the constructed solutions. This implementation was integrated into a client-server application by developing service in Python using Flask based on REST API interaction.
