Forecasting of demand for direct production materials as the element of supply logistics of thermal power plants

The paper highlights the problems associated with the process of forecasting realized within the supply logistics in thermal power plants. The theoretical part focuses on the importance of forecasting of inventories of raw materials in thermal power plants and the quality of logistics decisions determined by utilitarian value of data obtained, stored, processed and transmitted within the logistic system. The practical part presents the results of studies conducted in one of the thermal power plants in the south of Poland and the results of forecasting of the demand for the materials directly used in manufacturing process.
