Modelagem e simulação computacional do processo produtivo de embarcações produzidas em aço em um estaleiro de Manaus-AM

Abstract

The shipbuilding industry is characterized by variability in their level of activity, as work by hiring custom work. Thus, the production companies that work with custom face difficulties in their production sequence in an attempt to reconcile high rate of utilization of productive resources with the time of delivery. The main participants in the international market of shipbuilding following strategies of specialization. Manufacturers seek Brazilian expand, specializing in the manufacture of offshore support vessels, tankers and containers door-to coasting. In Manaus (AM), the largest shipyards to build vessels in steel, has as its main product the rafts and pushers, driven by demand for grain and minerals industries of the region. For methodological procedures for this work were used quantitative and qualitative data. Initially, a literature search. Then went to the field research, conducted at the Shipyard A, where he collected the data. It appears that both steps were necessary and are complementary, so that could explain the first empirical research that was developed after the event. In the study of the production process of the Shipyard A, it was possible to understand the relationship between of each steps. Thus, we developed mathematical models and software that represent the production system. By applying methods of Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM), has developed a proposal for a production system with the possibility of reduction of the production of a raft of 60 to 26 days, reduction of 56. 6%. To obtain this result, it would be necessary to increase the number of labor, this investment is justified only to constant demands for ferries. Then, have developed computer simulation models in the software arena, thus enabling the generation and manipulation of scenarios of the system under study without monetary damages and maintaining the physical integrity of those involved.
