PACHECO, José Vinícius de Avila  and  MORABITO, Reinaldo. Cash management network flow optimization: application within an agroindustrial company. Prod. [online]. 2010, vol.20, n.2, pp.251-264.  Epub Apr 16, 2010. ISSN 0103-6513.

In this study we formulate the cash flow management problem encountered in a typical agroindustrial company as a network flow optimization model (with gains and losses) proposed in Golden, Liberatore e Lieberman (1979). The objective is to maximize the cash return of the financial resources at the end of a multi-period and finite planning horizon. Two examples are studied applying linear programming: in the first, the original network flow model is used to support operational cash flow decisions and in the second, the model is extended to deal with a tactical planning of loan payments. The mathematical models are solved using the optimization tool of a widely-used software spreadsheet package. The numerical results obtained show that the models are flexible and effective, being able to generate solutions, equal to or superior to the company solutions.
