Abstract
We analyze the influence of aging on the reliability of a two-component
standby system with switching failures (2SBSF). When the backup component is
aging in standby as if it is working, we have a 2SBSF with full aging. Typically,
such a system is modelled with a rate diagram (where the failure rates are time-dependent) which has an adjacent system of 3 ordinary differential equations (ODEs).
The reliability characteristics of the 2SBSF with full aging can be obtained from
the numerical solution of the formulated Cauchy problem. Alternatively, simulation
modelling can produce the same results, but without using the rate diagram. In that
way we can adapt the simulation algorithms to treat the cases when either the backup
component does not age in standby (2SBSF with no aging), or when the backup
component ages in standby slower than in operation (2SBSF with partial aging).
In the last two cases there is neither rate diagram, nor a system of ODEs since the
2SBSF is not state dependent when the full aging assumption does not hold. We
develop ten algorithms to facilitate the simulation solutions of the 2SBSF with no
aging and with partial aging. We emphasize on the ways to deal with the numerical
problems created by working with truncated distributions and with random sampling
