The authors of this paper present, a method for building a model of technical objects operation whose sequence of successive operation states, their duration times, incomes and costs connected with the objects being in these states and the way a given state is reached depend not only on the object current state but also on other factors. The model describes, among others, influence of damages of the powertrain, being a compression-ignition internal combustion piston engine, of the analyzed object on the operation process of that object. The analysed technical object is a means of transport (a vehicle). A simplified computing model has been presented in order to illustrate the discussion. The model of operation process was built basing on the analysis of spaces of states and operation events concerning technical objects used in a real transportation system. In result of identification of the analyzed system and its multi-state process of technical objects operation, operation states and possible transitions between these states, significant for this research, have been determined. Sets of source data indispensable for the model assessment and its initial verification were obtained on the basis of experimental tests with the use of passive experiment method from a real research object. In order to perform mathematical modelling of the technical object operation process the Markov decision process was applied.
