*1.3. Objectives and the Paper Content*

The main subject of this research was the impact of the occurrence of power limitation on the production system. The production system is a deliberately designed and organized system, within which the available resources are used to produce specific products that meet the consumer needs [5]. This system is based on the execution of the production process, using four key resources. The resources include material resources, human resources, information resources, and capital resources. In the last few years, more and more attention has been paid to including the energy component in the definition of the production system. This component is one of the inputs to the manufacturing process. Electricity makes it possible to perform technological operations on machines as well as to ensure the functioning of the entire production environment.

It is likely that soon, both the increase in electricity prices and the reduction in the availability of electricity may constitute one of the main challenges for manufacturing companies. In this context, this paper aims to propose a method that would enable manufacturing companies to analyze electricity consumption in rapidly changing production conditions. In particular, the method should answer the question of how the constrained availability of power or large differences in electricity prices between different times can be compensated by changing the production plan. A change in the production plan is understood as an extension of the execution time for a given production batch, moving the execution to another time, or determining which part of the production batch will not be completed on the previously planned date. This type of approach has not been considered in the literature thus far. The main conclusion of this paper is that with the help of available simulation modeling programs, it is possible to analyze electricity consumption in production processes and draw practical benefits for the company. An additional conclusion is the possibility of developing and applying the proposed method to various production processes, which requires further research.
