Problem of building optimal procedure for complex technical systems logistics, when aforementioned provide continuous service is discussed. Target function takes into account supplies levels that ensure minimal expenses level C with constant logistics reliability R. To calculate expenses and logistics reliability in two-level strategy analythical restocking model suggested based on semi-Markov processes. Conditions of practical application are found. Algorithm for calculating probabilities of process being in a specific state with compact analythical equations for practical purposes are listed. Heuristic algorithm for finding supplies levels ensuring minimum expenses level with fixed logistics reliability is built.
