Análisis de confiabilidad, mantenibilidad y disponibilidad mediante la aplicación de la distribución de Weibull. estudio de caso separadoras de aceite Westfalia de la empresa Agip Oil Ecuador.

Abstract

The present investigation "analysis of reliability, availability and availability through the distribution of Weibull, a separate case study of Westfalia oil from the company Agip Oil Ecuador", aims to determine the reliability, updating and availability, measurement objective and optimization of the maintenance management. The maintenance regime of this equipment has been carried out for almost 18 years without adapting the plans to its operational context, nor to its recovery solution. The analysis of the CMD indexes is the only technical and scientific measure, which allows the average repair time (MTBF), allows the analysis and integral evaluation of the planning, execution and control of maintenance management. Through the FIASOFT software, the correct operation and repair times recorded in the operation log were processed. Average time indices between faults and average repair time were calculated. The prediction equations for reliability, availability and availability were determined, which allow these indices to be estimated for the time value "t". The values of generic, inherent, reached and operational availability of the equipment were estimated; These values revealed shortcomings such as maintenance and a slow response to the requirements of resources and materials. It was concluded that maintenance frequencies can be reduced, so it is recommended to increase the frequency of preventive maintenance from 500 hours to 1000 hours.
