MATHEMATICAL AND ECONOMICAL MODELING OF SUPPLY CHAIN, CASE STUDY: DAIRY RIO – ALGERIA

In this article, we will try to show the effective role played by the forecast methods of sales to manage an extremely important function in the firm which is the supply chain management. However, we point the way to use the data of forecasting in the mathematical modeling for the supply chain which is distinguished by the multi purposes objectives. Modeling can be done by using different models such as goal programming model with its different variants that can be adapted to the case studied, and referring to the work of specialists in the field (Ignizio JP (1982), Charnes A . and WW Cooper (1961), Martel and JM Aouni B. (1990)), the method of Box and Jenkins, mathematical programming with multiple objectives etc. Modelingwill be done by using the method of Lot-sizing while the resolution will be through the use of multi-criteria methods. In our particular case, we will try to apply them to the “RIO firm” an important Algerian firm in producing yogurt. These methods and results will be used by the “Rio company “officials in their strategic management and mainly the supply chain of products.
