EVALUATION OF THE DEPENDABILITY INDICATORS OF THE RESTORED EQUIPMENT BY THE SIMULATION METHOD
P. 207-211.
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.

Traveling wave tubes (TWT) are widely used in power amplifiers for radio means of information transmission, including in space equipment. This is due to the fact that for them there are high requirements to ensure dependability, for example, due to the lack of possibility of maintenance for a long period of active existence. Hence the ...
