Opis:: The problems presented in this article deal with operation and maintenance process control in complex systems of technical object operation and maintenance. The article presents the description of the method concerning the control availability for technical objects (means of transport) on the basis of the mathematical model of the operation and maintenance process with the implementation of the decisive processes by semi-Markov. The presented method means focused on the preparing the decisive for the operation and maintenance process for technical objects (semi-Markov model) and after that specifying the best control strategy (optimal strategy) from among possible decisive variants in accordance with the approved criterion (criteria) of the activity evaluation of the system of technical objects operation and maintenance. In the presented method specifying the optimal strategy for control availability in the technical objects means a choice of a sequence of control decisions made in individual states of modelled operation and maintenance process for which the function being a criterion of evaluation reaches the extreme value. In order to choose the optimal control strategy the implementation of the genetic algorithm was chosen. Depending on one’s needs, the genetic algorithm including the obtained model of operation and maintenance process may be implemented for mathematic formulation and solution of a wide array of problems connected with control of complex systems of technical object operation and maintenance. It pertains mostly to the economic analysis, safety management and controlling availability and reliability of complex systems. The opinions were presented on the example of the operation and maintenance process of the means of transport implemented in the real system of the bus municipal transport.

Opis:: In this article there is presented a description of a method for control of the operation process in a complex operation system of technical objects operation where semi-Markov decision processes are used for control. The study has been based on the operation process of a real bus municipal transportation system. For complex systems of technical objects operation, it is possible to achieve the set goal – appropriate accomplishment of the assigned task (tasks) with required efficiency - only when the control decisions, made by the system decision-makers, are rational. In systems where the complex operation process of technical objects is carried out, the choice of rational control decisions (from possible variants) is an issue of great importance and difficulty. In real complex operation systems of technical objects operation, the process of making control decisions should be carried out using mathematical procedures and methods, rather than according to the system decision makers' intuition or experience. Use of appropriate mathematical methods for control of the operation process facilitates the choice of rational control decisions providing correct and efficient accomplishment of the assigned tasks. The presented method involves elaborating a mathematical operation model (semi-Markov model) and choosing the best control strategy (from possible decision variants), according to the accepted criterion (criteria) of technical objects operation system assessment.
