| Abstract | |
The foundry industry produces plenty of different items present in various sectors of the economy. Such items range from simple household gadgets to sophisticated devices used by basic industries and the auto parts sector. This industry is important for the Brazilian economy and studies aiming at the improvement of its efficiency are fundamental to ensure its competitiveness worldwide. As highlighted in the literature, an important factor that influences the production in the sector is the produiction planning.; In recent years, the investments in this area have been increasing and more attention has been drawn by academic studies. This dissertation deals with the production planning in small foundries, whose major decisions are the determination of the alloys to the merged and items to be produced. A question that still has not considered in the literature is the obligation to complete the production of the orders to be delivered to the client. However, in many real cases, an order cannot bi partially delivered, that is, the pieces, which are parts of the order, may be pats of the final product. In other cases, the order may be partially delivered, but with additional expedition costs. In this dissertation the objective is close that question, so we propose: (1) a mathematical model for production-planning problem of complete orders for small foundry industry; (2) a mathematical model to treat the possibility of partial delivery to the sama problem. Furthermore, we proppose a Relax-and-Fix heuristic for the integrated model (AU) | |
