Escalas de trabalho utilizando programação linear: viabilidade na operação remota de usinas

Abstract

Due to the constant need for cost optimization and realizing this market opportunity, this present study verifies the feasibility of creating a OGC (Operation and Remote Generation Center for Small Hydroelectric Plants). A linear programming model was prepared to find the optimal solution to the problem by Simplex Method. This model is based on the classic work schedule problems, with modification of the objective function in order to minimize the costs involved, taking into account the functional restrictions. The model was implemented through the Solver supplement from Microsoft Excel spreadsheet. In the variation of the restrictions, two types of working hours that were widely used were considered when it is necessary that the working periods include 24 hours a day and 7 days a week. The objective function, decision variables and restrictions were defined in the methodological phase, using PL concepts and information raised in the case study. In the results obtained in this work, the best scale to be used is 6 x 1, a scale that meets the restrictions and presents the objective function with the lowest cost, that is, a scale that allows greater viability for creating the OGC.
