CLOSED SUPPLY CHAINS IN A CIRCULAR ECONOMY: EFFECTIVE INVENTORY MANAGEMENT

Анотація

The world economy is characterized by linearity, namely the model "product of raw materials-production-consumption". This concept has already lost itsviabilitydue to a number of factors, namely: the depleted global ecological system, socio-economic and resource constraints. Through various environmental contaminants sharply reducedand thequality of life disappear goals populations of animal and plant life. Today, there is an alternative to the linear model of the economy - a circular economy, the main task of which is to restore the ecosystem, saving resource potential, financial and human resources through reverse and careful treatment.To form a new model of economy, governments of developed countries use different tools, but there is not always an understanding of the importance and effectiveness of this concept. The article considers the essence and basic principles of circular economy. As a basis for the implementation of the concept of circular economy are considered closed supply chains and as the main tool for the implementation of tasks - reversible logistics.Managing reverse logistics is a complex task that requires a systematic approach and significant resources.The goal of building reverse flows is to reduce costs and increase profits.The author's interpretation of the essence and content of reverse flows in closed supply chains, which include return and return flows, is presented in the article..The constituent elements of reversible material flows in closed supply chains are investigated.The main problems in the formation of closed supply chains are identified, namely the optimization of inventory management throughout the chain.A methodical approach to inventory management in closed supply chains, which provide for multilevel inventorymanagement, is proposed.The use of a set of inventory management modelsthat allow to coordinate actions for inventory management and are adequate to the practice of doing business in a circular economy.Conclusions and recommendations on the peculiarities of the formation of closed supply chains, the list of flows as elements of reversible logistics, methodological approaches to the use of inventory management models in complex logistics systems built on a circular basis (circular).
