This paper is devoted to the development of formal procedures for calculating inventory management parameters for a model with a fixed interval between orders. The urgency of transition from informal methods of regulation of insurance stocks to formal economically justified procedures for calculating their planned values is shown. The article presents an analysis of the concept of "logistics service" in the context of its use in determining the value of the safety stock. The main approaches to determining the target value of the safety stock depending on the level of logistics service are considered. There are known difficulties in determining the dependence of the level of logistics service and financial performance. In this regard, it is proposed to use the equation of total costs of replenishment and maintenance of reserves, including deficit costs, as a basis for determining the parameters of inventory management based on cost minimization. In this case , the service level is treated as a derived value that corresponds to the minimum total cost condition. A method for determining the parameters of inventory management for a model with a fixed period is developed. The algorithm of calculations is tested on an example.
