The article presents the most important information concerning the methods, techniques and indicators of I measures, which are used in the evaluation of production processes. The theory of limitations, process mapping, benchmarking and diagnostic test method have been described. Sample indicators for the evaluation of production processes are presented and the measures for the evaluation of production processes are discussed, as well as methods of obtaining information about the process. The modelling and computer simulations were described and the algorithm of proceeding during the development of a simulation model was presented. The article discusses system dynamics modelling, discrete event modelling and agent modelling.

The article presents the most important information concerning computer modelling and simulation, system dynamics modelling, discrete event modelling and agent modelling. An exemplary model of the production process of windscreen wipers, which was created on the basis of assumptions, discussed the individual components of the model. An example of using JAVA code in AnyLogic program is presented and examples of indicators that can be calculated and presented in the form of a graph in the program are shown. Computer simulations enable tracking and analysis of the production process. They help to verify assumptions and detect irregularities in the modeled process. Simulation programs have a wide range of possibilities, allow you to create reports, charts, comparisons, allow you to optimize processes.

W pracy przedstawiono zagadnienie modelowania układu drgającego odbierak prądu -sieć trakcyjna jako modelu dyskretnego z masą zredukowaną sieci trakcyjnej jako zmienną w czasie. Wykazano, że w publikacjach zagranicznych dotyczących tego tematu nie uwzględnia się definicji siły jako pochodnej pędu względem czasu, co dla układów o zmiennej masie jest szczególnie istotne. W pracy przedstawiono porównanie wstępnych wyników ,symulacji wybranego modelu układu odbierak prądu - sieć trakcyjna z uwzględnieniem w równaniach ruchu układu pochodnej masy względem czasu i bez jej uwzględnienia. jak to jest stosowane w literaturze zagranicznej.

This paper is concerned with the dynamics of the overhead contact system for current collection on electrified railway lines. Presented paper consist an especially problem of time-varying mass in dynamics. This problem exist in modelling of railway pantograph-overhead catenary system vibration too. In this domain various model s are introduced to describe the overhead equipment and the pantograph. Author of this paper presents own experiments and results of computer simulation. For this reason the simplified model of pantograph-catenary system was used.
