Improvement of inventory management is especially important due to their high share in tangible working capital and trends of their increase, which causes the freezing of material resources and a decrease in the efficiency of their use. At the present stage of development of productive forces at sharp growth of volumes of production when communications between the enterprises became complicated and the nomenclature of material resources increased, the guaranteed material maintenance of production is possible only in conditions of creation of scientifically proved system of management of material resources at all levels of managing. Growth of efficiency of use of stocks is a large reserve of increase of economic efficiency of the enterprises.
