Resumo
The goal of this work is to propose the application of a mathematical model, which couples the lot sizing and stock cutting problems, to a real case of a factory, in order to minimize the production costs. Two final products of the manufactory are considered. Costs and demands vary over periods of planning. Numerical results from this study are compared with the case whose production is made considering the demand by period. The optimal solutions obtained from the model are promising, since they provide a considerable profit in relation to the production by demand.
