MARTINS, José L. F; FERREIRA, Miguel L. R; PARDAL, Juan M  e  MORANO, Cássia A. R. Comparison in estimating productivity of Shielded Metal Arc Welding process through Monte Carlo and Latin Hypercube Sampling Simulation Methods. Inf. tecnol. [online]. 2012, vol.23, n.4, pp. 21-32. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000400004.

The ability of Monte Carlo simulation and Latin Hypercube Sampling methods in estimating the productivity of the Shielded Metal Arc Welding (SmAW) applied in works of industrial piping assembly based on small samples is evaluated. The study was conducted by analyzing a sample collected from assembly operations done at refinery Duque de Caxias, Rio de Janeiro in Brazil. The ControlTub 5.3 software was used for data acquisition and MathWorks in the simulation step. For data analysis the results were compared using the proposed simulation methods. Then the similarities and differences between the methods to estimate the process productivity in analysis were evaluated. The results demonstrated the feasibility of applying the methods of Monte Carlo Simulation and Latin Hypercube Sampling in estimating productivity considering a welding process of industrial pipes.

Palavras-chave : productivity; welding; Monte Carlo simulation; Latin Hypercube Sampling.
