MUNHOZ, José Renato  y  MORABITO, Reinaldo. A robust optimization approach for the aggregate production planning in the citrus industry. Prod. [online]. 2013, vol.23, n.2, pp.422-435.  Epub 02-Ago-2012. ISSN 0103-6513.

In this work, a frozen concentrated orange juice aggregate production planning is modeled taking into account uncertainty in some parameters. This generates an effective tool to support decision making. The robust optimization approach is based on a linear programming model with multiple products, stages and periods proposed by Munhoz and Morabito (2010). Besides decisions in the production, blending and storage of juices, the model also includes an orange harvesting plan, which considers orange maturation curves. A case study was developed in an orange juice company located in the State of Sao Paulo. This company has different facilities and a worldwide distribution system. The computational results obtained from this robust optimization approach, using an algebraic modeling language and a state-of-the-art optimization solver; indicate that the approach can be useful in real situations.
