The degradation of natural resources and environmental pollution compels companies to be concerned about the negative impacts that their activities may have on the environment. This new way of thinking is too essential to final supply of supply chains. By the day, using the products, using this product, using this product using can-it. Managers are therefore on the planning of sustainable closed-loop supply chains. This makes it possible to directly manage the reverse flow of logistics networks in order to make end-of-life products profitable. These are the companies that can earn profits without causing harm to those around them and thus endure over time. It is in this logic that we work, that we aim more particularly the simultaneous optimization of the production of new products and the recycling of used products.
We need researchers and propose an effective model. We studied literature, two mathematical models: a model for analyzing tactical decisions with a closed-loop supply and a model with a record of decisions in the same chain. The reasoning applied is described as follows. First, we have to solve the first mathematical model, which we have opted for an optimal supply and production plan in the case where the drugs were sent. Results by an analysis of sensitivities. Then, the second model is completed when factories are subject to random events. The robustness of this model is also tested by sensitivity analysis.
