ROCCO, Cleber Damião and MORABITO, Reinaldo. An optimization model for the operations of steam production in industrial boilers. Gest. Prod. [online]. 2012, vol.19, n.2, pp. 273-286. ISSN 0104-530X. http://dx.doi.org/10.1590/S0104-530X2012000200004.
In this study, a mixed integer linear programming model is presented to support some of the key decisions in the steam production system with industrial boilers. The model approaches the fuel management decisions (fuel replenishment and its inventory control), boiler operational decisions (start-up, warm-up, and shutdown operations), and which boiler should produce steam. The model adjustments and its validation were carried out through a case study in a large food industry. In face of the good outcomes achieved in applying the model and the lack of optimization tools to support the decisions in this system, the proposed model is a suitable alternative to support some of the key decisions in the system of steam production with multiple industrial boilers.
