ON OPTIMAL RESERVATION IN INFINITE INTERVAL
In this article we consider system reservation model with discrete time. As the reservation strategy criterion we choose mean time between failures on an infinite interval. According to experimental data no-failure operation interval consists of disjoint K0-constancy intervals. We obtained the conditions by which optimal strategy is switching on two elements in system. Interval limits are obtained where K0(r) is equal to 2. Then problem about null strategy optimality was investigated. It is proved that null strategy has never bееn optimal for the model. It means that when system functions on infinite interval we shouldn’t switch on all elements at once (if we have more two elements). These results simplify optimal strategy search algorithm for given model and can be used for improvement of the quality index as mean time between failures.
