The work presented in this thesis concerns the problem of sizing and sequencing batch production, single level, skilled (CLSP), in a manufacturing plant precast concrete used in construction, where the sizing and sequencing of lots production in a given period, represent a challenge for the company, which in turn seeks to minimize the costs of production, inventory, setup and improve the level of service customers' demands. The problem consists in defining the size of lots and production sequence of several blocks precast concrete in a press line, with setup times too high. It was proposed, therefore, a mathematical model whose objective is to minimize the costs of production, setup and inventory, involved in the manufacturing process of these products through the exact method of Integer Linear Programming. The presented model aims to solve the problem was proposed and applied to the real situation of the company for the purpose of comparison of current results with the results after application of the model .
