Abstract. The issues of ensuring the reliable functioning of complex technical systems during operation by carrying out scheduled maintenance with the use of controls are considered. The possibility of conducting simulation modeling in order to evaluate the most important indicators of system reliability, for example, the availability coefficient, taking into account the metrological characteristics of the control means, is being investigated. The study is declared to be of great importance for confirming theoretical statements about the influence of quality control on reliability indicators. Analytical and simulation models for assessing the readiness indicators of a complex technical system are proposed. Simulation modeling is carried out on the basis of the AnyLogic software environment, the obtained results are used to construct dependences of the system readiness coefficient on the metrological characteristics (control errors) of applied control tools and service parameters.

Keywords: model, technical condition control, complex technical systems, simulation modeling, AnyLogic, readiness factor
