This scientific paper deals with the real-time reliability simulation of the restorable technical systems with identical elements and arbitrary reliability structure using multithreaded programming for the Microsoft® Windows™ operating system. The offered by the author algorithms for simulation of each of the system elements and estimation of the stationary availability factor using the simulation results are discussed. The developed by the author software implementation of the offered algorithms for reliability simulation of technical systems is also presented. Finally, an example of reliability simulation of the technical system with identical elements and bridge reliability structure using the developed reliability simulation program is also given.
