The economic relationships of essential oil production as a basis for supply chain modeling

This article reveals that essential oil production is a complex system with a large number of economic ties arising in the process of growing and processing as well as distribution of products made from essential oils raw materials. Multileveled manufacturing process of essential oils products requires coordination of all the elements to reduce costs in the entire supply chain. It is proposed to use mathematical modeling of the supply chain based on the method of main faces, which allows to take into account the specifics of the problem and makes it possible to use a variety of combinatorial and heuristic algorithms.

Literal framework of Green supply chain Modeling

Supply chain covers a set of logistics components (procurement, storage, production, distribution...). In addition to the classical logistics components, the green supply chain integrates the environmental dimension in all these components. Nowadays modeling a supply chain by integrating environmental constraints has become an important metrics, in the logistic field for scientists, and also for industrialist in order to meet the customer needs, that has become more and more demanding in terms of respecting environment. This article aims to summarize some literature studies of the green supply chain and its modeling; afterwards we will expose an overview trough a comparative study about the used methods and approaches in the green supply chains modeling.
