Models of Production Systems as a Condition of Maintaining Their Stability

Article presents the possibility of using computer modelling and simulation methods for assessing the risk and stability of production systems. Analysis of the stability depending on the occurrence of risk factors was presented through the example of a bogie frames manufacturing plant undergoing reorganization. In order to ensure smooth functioning of a production system, the stability of its processes must be guaranteed, as well as possibility of making fast decisions with the lowest risk rate must be ensured. Products’ and processes’ innovations constitute the ability to remain on the market; however, they incorporate the risk of losing stability. The risk results from the uncertainty associated with making decisions far into the future, as well as from the fact that the implementation of innovations is one of the factors that disturb the current manner of operation of the enterprise. The stability of a production system is defined as maintaining the steady state by the system for a certain period of time.
