The article presents a special modification of the EOQ formula and its application to the accounting of the cargo capacity factor for the relevant procedures for optimizing deliveries when renting storage facilities. The specified development will allow managers to take into account the following process specifics in the format of a simulated supply chain when managing inventory. First of all, it will allow considering the most important factor of cargo capacity when optimizing stocks. Moreover, this formula will make it possible to find the optimal strategy for the supply of goods if, also, it is necessary to take into account the combined effect of several factors necessary for practice, which will undoubtedly affect decision-making procedures. Here we are talking about the need for additional consideration of the following essential attributes of the simulated cash flow of the supply chain: 1) time value of money; 2) deferral of payment of the cost of the order; 3) pre-agreed allowable delays in the receipt of revenue from goods sold. Developed analysis and optimization procedures have been implemented to models of this type that are interesting and important for a business. This — inventory management systems, the format of which is related to the special concept of efficient supply. We are talking about models where the presence of the specified delays for the outgoing cash flows allows you to pay for the order and the corresponding costs of the supply chain from the corresponding revenue on the re-order interval. Accordingly, the necessary and sufficient conditions are established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to real opportunities to improve the efficiency of inventory management systems by taking into account these factors for a simulated supply chain.

Pursuant to the statistics data of Eurostat, the economy of European Union is slowly recovering from year lasting recession. The gross domestic product volume increased in 2nd quarter of the year 2013 by 0.3%. The industrial companies in EU are nevertheless facing still increasing competitiveness as the European and global markets are developing under current business conditions. To be successful within the frame of current supply chains the companies must have well-developed logistics management systems to effectively treat with flows streaming in their inner or outer supply chains. One of the main elements of company logistics management systems is inventory management subsystem to plan, to manage and to control particular stock items. In the paper it is briefly described the methodics to design effective inventory management system whether in industrial or service company.
