CATEGORY  Inventory management Optimization and mathematical modelling Supply chain management



 In the theory of inventory management, various models of inventory management are widely known. All of them are based on two fundamental factors: order size and the time between two adjacent deliveries. The variety of additional conditions (discounts depending on the size of the delivery lot, penalties due to deficits, the volume of safety stock, etc.) make the task of developing a working model to minimize total costs extremely difficult. It is another factor that looks interesting - the multi-level structure of reserves allocation.
In (Aslakhanov A.R., 2017; Lukinskiy V.V., Aslakhanov A.R., 2017), an integrated inventory management model was developed that would take into account deficit costs, randomness of demand and logistics cycles duration, as well as a predetermined planned level of end-user service. The model was developed for cases of two-level supply chains, which is a serious limitation for applying the model in practice.
In this paper, the model will be expanded for the case of a three-level linear supply chains in order to assess the scalability potential of the developed model for business situations and to assess the possibility of using the developed model in conjunction with reinforcement learning methods.

Supply chain management is one of the main sources for competitor advantages. Market environment claims more and more requirements for its participants, increasing logistics efficiency in particular. Diminution of costs is the main stream of optimization. Wherein reducing of logistics costs, and as a result, increasing enterprise competitiveness, can be achieved due efficient logistics.

The growing interest in increasing supply chain efficiency claims the higher requirements to assessment system of logistics. This is due to logistics methodology, which allows integrating different aspects of economic knowledge in order to develop new scientific ideas within material, financial, service and information flows. That provides the increase of supply chain and optimization of flow distribution insuring social impact and ecological requirements. 

The article contains methodological approach, which allows including transport indicators to total logistics costs model. Developed equations provide the ability to estimate dependence between transports operations on TLC (total logistics costs) on the base of integrated method of economic analyses.

Developed methodology is supposed to be used for analyses of dependency between transportation costs and TLC; and dependence between production indexes and transportation costs.

The paper presents an approach to the formation of strategic decisions in the supply chain associated with the distribution of limited resources, the choice of the circuit configuration, definition functional and organizational structure of the supply chain, based on the analysis of the interrelation and mutual influence of logistics functions using the criterion of General logistical costs.
