This paper attempts to apply modeling methods using the UML language for designing a computer-based system for the operation of complex objects. In particular, emphasis is placed on describing the system’s dynamics, understood as the variability of behaviors resulting from interactions with the environment. A system for supporting the operation of railway traction vehicles was chosen as an application example.In the economy of every modern country, there are many objects of high value and relatively long service life, during which phases of utilization and maintenance alternate in accordance with operational principles (e.g., means of transport such as land vehicles, ships, aircraft). The acquisition cost of an object is often significantly lower than the subsequent total expenditures on operation during its service life.
Rationalizing operation can at some point lead to the withdrawal from service of objects that are technically capable but obsolete due to the presence on the market of objects with significantly higher technical parameters or definitely lower operating costs[4].
A synthetic approach to phenomena and making correct decisions related to them is impossible without appropriate computer systems that provide the background for business processes. The need to create Computer-Aided Operation Support Systems (KSWE) is also a result of changes in maintenance processes and the replacement of traditional inspection and repair cycles with condition-based maintenance based on current diagnostics. Thus, it is essential to continuously collect reliability data and operational parameters from individual objects being operated. On-board diagnostic systems are helpful in this case,

however, in order to obtain data regarding the entire population of objects and draw more general conclusions, their aggregation is necessary. (…)
