The model presented in this paper includes a setup time for the production of a lot of an item. The production of items in a given period is constrained by a limited regular time and a limited overtime. Moreover the production level of any item in a given period is also limited. This problem is tackled by the Cross Decomposition method which can provide an optimal solution or a near optimal solution if computational time is restricted.  aresource allocation  aDecomposição cruzada  aDimensionamento de tamanho de lotes  aLot sizing with setup times  aMulti-item lot sizing  aPesquisa operacional  aPlanejamento de produção  aProgramação inteira1 aARMENTANO, V.
