Modelo matemático para la optimización del plan maestro de producción para lácteos

Abstract

The company under study is mainly dedicated to the manufacture of dairy products, both liquid and powder, in different functionalities or profiles: whole, skimmed and deslactosed. For production planning, the company has a traditional process, which projects a weekly production plan with the objective of satisfying the demand while looking to maintain an inventory and control production costs according to a pre-defined policy. The company has two major challenges: the first is to maintain a balance between the consumption of a regular volume of milk and the efficient use of surplus fat, while satisfying the demand. The second challenge is to ensure the correct use of factory assets by controlling the levels of stocks and production lots. The company currently does not have an adequate tool to fulfill these purposes. This study seeks to design a mathematical model that helps to develop a manufacturing master plan that allows to meet projected demand, keep inventory at the appropriate levels and comply with production considering capacity constraints.
