The real operation and maintenance processes of technical objects are characterised by so called secondary action, it means that the values of the features describing the process states and the analysed operation and maintenance states of technical objects as well as the after-effect ofthose states depend not only on their present state, but very often on the state or sequence of the previous states, too. In spite of the fact that the mathematical models of the real processes are intrinsically a significant simplification of the actual state, it however seems that omission of a secondary action in a certain class of operation and maintenance processes is an excessive simplification and the results obtained from investigations of models of that type may be affected by a significant error. The paper presents a model of operation and maintenance process of means of transport characterised by a secondary action as well as an example of computer simulation of performance of a stochastic process describing the features of the operation and maintenance process under analysis. The elaborated model of operation and maintenance process of technical objects takes into account the specificity of the systems of the urban bus transport. The computer simulation of the maintenance process enables, among other things, to estimate the values of the chosen indicators characterising the investigated process. On the basis of the analysis of the statistical data, obtained from the operation and maintenance investigations, the values of the essential input parameters of the model were estimated. The considerations presented in the paper include an assumption that it is possible to distinguish n disjoint subsets ofhomogenous objects, from the point of view of the investigation purpose, in the set of the technical objects being operated and maintained in the system under analysis. The investigation object is a system of operation and maintenance of means of transport.
