RÉSUMÉ

Models of the systems of service with perishable stocks under the presence of different types of requests are proposed. It is foreseen that some requests after completion of their service do not buy stocks. Time of the requests service and time of stocks replenishment are positive random values. The policy of refreshment belongs to a class of two levels. The exact and approximate methods for determination of main characteristics of the suggested models are developed. High accuracy of the adduced formulas is shown by means of numerical experiment.
