Estimativa da produtividade em soldagem pelo Método de Monte Carlo

Abstract: ResumoO objetivo deste artigo é o de analisar a viabilidade da utilização do método de Monte Carlo para estimar a produtividade na soldagem de tubulações industriais de aço carbono com base em amostras pequenas. O estudo foi realizado através de uma análise de uma amostra de referência contendo dados de produtividade de 160 juntas soldadas pelo processo Eletrodo Revestido na REDUC (refinaria de Duque de Caxias), utilizando o software ControlTub 5.3. A partir desses dados foram retiradas de forma aleatória, amo… Show more

“…To perform a stochastic simulation, we can use the Monte Carlo method, which, according to Martins et al (2011), consists in the generation of pseudorandom numbers from a real sample. To Oliveira and Pamplona (2012) in the Monte Carlo method, the main project uncertainty sources that can serve as input variables for the simulation can be: revenue, discount rates, costs, and expenses, among others.…”

“…Gelisen and Griffis (2014) have developed of a model to automatically update the performance indicators of a project, estimating the impact of events and activities on labour productivity. Constâncio, Ferreira, and Freire (2009), Saraiva (2011), andMartins et al (2012), applied a methodology based on Monte Carlo simulation to estimate the productivity of welding of butt joints in carbon steel pipes, based on small samples. Sensitivity analysis is used for a wide range of purposes.…”
