The object of the investigations is maintenance system of urban transport buses. The subject of the investigations is a determined set of the maintenance states of means of transport and their maintenance processes, as well as the relations occurring between the aforementioned elements, and between them and the maintenance process effectiveness. The paper deals with the selected issues related to modelling, forecasting and controlling the maintenance process of a certain class of technical objects being carried out in a complex maintenance system. Supporting a decision maker in the decisions making process concerning the maintenance system under analysis is to forecast the maintenance system behaviour and evaluate the influence of the selected decision making variants on the course of the maintenance process. The purpose of the work is to present a possibility to use a semi-Markov model of maintenance process of technical objects to preliminarily forecast the state of the maintenance system after changing the values of the model input parameters. Changing the value of the input parameters may simulate an impact of various factors on the system behaviour. The paper presents the assumptions to build a model of the process being performed within the investigation object and the method of analysing it. The values of the model parameters were assessed on the basis of the results of the preliminary test carried out in a real means of transport maintenance system. All the considerations have been illustrated by a computational example. Due to the assumed generalization degree of the description, the method to model and forecast the maintenance process presented herein may be used to other maintenance systems than the urban bus transport system.
