The model of stochastic optimization of inventory level of nonrenewable spare parts for unreliable industrial equipment is studied. The processes of equipment’s work, its failures/renewals, and supply of spare parts are described in the terms of Markov drift process. For manufacturing system “equipment park (production line) – warehouse for final product storage” the problem of optimum lot size of spare parts finding is formulated and analyzed (in steady-state regime).
