Elaboración de una metodología para medir la mantenibilidad en los grupos electrógenos de la empresa POWERON

Abstract

The aim of this research is to develop a methodology in order to measure the maintainability of generators from POWERON Company which is located in Cumbayá. The analysis sample for this research is about 91 teams of three types of models and brands of different powers. To reach the goal several standards and studies on maintainability analysis were studied. Two techniques were identified: first the probabilistic calculation of maintainability related to probability of repair equipment after a failure, focused with corrective maintenance; second technical maintenance and evaluation of intrinsic maintainability related with the design which has an industrial device to be maintained. Particularly it treated tools like the Weibull distribution and quantitative calculation of the attributes of maintainability detailed in the standard UNE 151001, so these techniques are merged into one methodology that will allow continuous assessment of maintainability. It has improved average repair times from 11.72 hours to 5.6 hours, also high performance for Caterpillar equipment was determined, which were followed by Cummins, and eventually the MTU. The most important of the study is that it allows developing strategies in order to establish actions that promote continuous improvement and consequently increase equipment availability.
