Abstract
The study deals with the problems connected with modeling and simulation of technical objects operation processes carried out within a certain class of complex technical systems. The analyzed system is a city bus transport system. The study presents a method for assessment of unit costs involved in a technical object’s being in selected operational states. One of the subsets of data to be used for modeling the process of a technical object operational state changes, includes data concerning the costs borne by the system when the object is in the analyzed operational states. In order to determine this data, it is often necessary to modify the system of costs registration used in a given operation system. Since it is a very expensive and log process, a method of initial assessment of indispensable data has been proposed, on the basis of a costs registration method and simulation of the operation process. The study also includes basic assumptions of the operation process model, being an important element of the developed method. The assumptions of the operation model have been formulated on the basis of identification of a real operation system of city bus transport system and experimental tests carried out in system.

Summary
The technical objects analysed in the study are buses used in a public city transport system. In work [1], an example is given of a method used for the choice of technical objects to provide transport services, on the basis of a homogenous Markov process as the operation process model, whereas in work [2], economic aspects connected with a purchase of a transport means to be used in a public transport system, are discussed. The primary goal of a public bus transport system operation is to provide passengers with safe transport services within an assigned quantitative and territorial scope. One of the subsets of data necessary to conduct simulation experiments, is the one which contains the values of unit costs borne by the system while a bus (of a given type and form the identified category of objects [3]) is in the distinguished operational states. The results of an experimental simulation are based on input data obtained in this manner, they do not enable its qualitative analysis
