EVALUATION OF THE DEPENDABILITY INDICATORS OF THE RESTORED EQUIPMENT BY THE SIMULATION METHOD
P. 207–211.
Zhadnov V. V.
The report discusses the application of simulation modeling to dependability prediction of the restored equipment. A formal model is described that allows forming time diagrams of the states of both the components and the equipment as a whole. It is shown that the use of such a model allows us to estimate the availability function and the mean restoration time of the equipment if the law of the distribution of the restoration time of the components differs from the exponential one.
