AVALIA O DA PRODUTIVIDADE DO PROCESSO DE SOLDAGEM MAG POR SIMULA O COM O MéTODO DE HIPERCUBO LATINO

This paper deals with the analysis of the viability using the Latin Hypercube Sampling SimulationMethod to measure the productivity in the industrial MAG welding piping based on small samples. Thestudy was conducted by analyzing a sample collected in works made in Duque de Caxias Refinery (REDUC),in Rio de Janeiro, Brazil. The ControlTub 5.3 software was used for data acquisition and in the simulationit was used the Mathworks and the BestFit program environment. The data analyses of the obtained resultswere compared using the proposed simulation method, demonstrating its applicability. It also presentsan assessment tool productivity in real time, allowing for adjustments in estimates of productivity andmonitoring during the performance of the enterprise, enabling its evaluation not only in completing thework, which is the current industry practice. These results demonstrated the feasibility in applying themethod of Latin Hypercube Sampling in estimating productivity considering the MAG welding processin industrial pipes assembly and the capacity to build some evaluation scenarios, like optimist, mean andpessimist productivity.
