Resumo
The production process in an integrated steel mill produces gases, which can typically be used as fuel by the plant itself. However, managing the distribution of combustible gases is a complex activity, mainly because of the imbalances between production and consumption profiles of gases, the capacity and operational constraints of gas accumulators, and the constraints to energy use in power plants. The objective of this work is to use mixed integer linear programming (MILP) as a formulation for the problem distributing gases in the integrated steel mill, and to solve the formulated MILP making use of an algorithm that was developed using the Branch and Bound technique together with the Simplex method. Finally, the case studies confirm that the model is able to find an optimal solution for the proposed problem
