This study presents the problems connected with control of operation and technical objects maintenance systems. In particular, it discusses assessment and control of the availability of technical objects. In case of complex operation and maintenance systems, in order to control the availability it is essential to use the proper and effective methods and mathematical tools. The factors influencing the running and efficiency of the operation and maintenance process introduced in a complex system are of random nature. Most often the stochastic processes are used in mathematical modelling of the operation and in maintenance. In order to control the availability of technical systems, the following genetic algorithm was implemented on the basis of the semi-Markov model of operation and maintenance. Genetic algorithm may serve as a convenient tool to implement and facilitate the use of a complicated rational control decision making process in complex operation and maintenance systems. These include: systems operating machines, construction equipment, and means of transport. Due to its general character, the presented method may be implemented to solve a broad spectrum of optimization issues concerning the operation and maintenance systems. Among them are: controlling availability and reliability, analysis of costs and profits, and analysis of risk and safety.
