Avaliação dos fatores de impacto na produtividade da soldagem de tubulações industriais com o método de Monte Carlo

Abstract: O objetivo deste artigo é a apresentação de um método para avaliação dos fatores de impacto da produtividade na soldagem de tubulações industriais de aço-carbono soldadas com o processo Eletrodo Revestido. A metodologia utilizada baseia-se na simulação de Monte Carlo e em dados de produtividade coletados em obra gerenciada pela Petrobras na Refinaria Duque de Caxias (REDUC). A ferramenta utilizada é o “software” @Risk6.1 (2013), adaptado para avaliação da produtividade. Este “software” dispõe de recurso para e… Show more

“…The results in Table 4 indicates that the ratio between the average values of AP and BP is 0.52 for the diameter range between 1'' and 2 7/8'' and 0.48 for the range with diameters higher than 2 7/8''. This difference between the average values of BP and AP is a consequence of unproductivity owing to idleness, which ranges from 40 to 60%, covering unproductive times (Adrian, 2004; Gioia, 2015; Ney, 2016). According to Shehata and El-Gohary (2011), BP expresses the best possible execution conditions, where the events that imply production stoppage are smaller.…”

“…The sample used in the construction of modules for oil platforms of company A consists of historical data on the productivity of welders during the welding of pipes using the TIG process. Productivity is expressed in cm³/Mh (Ney, 2016; Lobato, 2015; Gioia, 2015; Tabim, 2013; PROMINP, 2009, 2010). Notably, the performance of welders in the Brazilian industry reaches a level of normality 10 days after the beginning of their activities (Martins, 2011; PROMINP, 2009).…”
