BARRERA GARCIA, Aníbal; CAMBRA DIAZ, Adrian  and  GONZALEZ GONZALEZ, Javier Antonio. IMPLEMENTATION OF SIX SIGMA METHODOLOGY IN MEASUREMENT MANAGEMENT. Universidad y Sociedad [online]. 2017, vol.9, n.2, pp. 8-17. ISSN 2218-3620.

This research was conducted at the Cienfuegos Refinery Business Unit. Its objective is to design a process for improving measurement management of the Diesel Hydrofining process using techniques related to Six Sigma. In addition, it is proposed to disseminate the repeatability and reproducibility studies of the measure (R & R), based on the experimental design. The percentage of variation due to reproducibility and repeatability in different tests involved in the analyzed process is determined, as well as the number of different categories (nc) that can be reliably distinguished by the measurement system. Two runs of the method are performed on the% Sulfur test; the first one identifies the variability present in the trials, from this first approach some adjustments emerge which are implemented by the company and the second run is planned aimed at improving the processes.  After the second cycle, a lower variability is obtained.

Keywords : Repeatability; reproducibility; measurements; six sigma.
