Pronóstico de la confiabilidad, disponibilidad, mantenibilidad y seguridad, mediante la norma ISO 3977-9 para optimizar la operación y mantenimiento del ascensor de la Facultad de Mecánica.

Abstract

The prognosis of Reliability, Availability, Maintainability and Safety, whose acronym in English is (RAMS) by means of the ISO rule 3977-9 to optimize the operation and maintenance of the lifter of the Faculty of Mechanics was made through the application of the Data Base of Reliability (OREDA) for all the mechanic components, since is the main source of feasibility data for the Oil Industry and the gas and sources like the (IEE <Instituto de Ingenieros Eléctricos y Electrónicos>) for the electric and electronic components, where these sources provided data in function of the time between failures, failures between repairing, the failure rate and the repairing rate, the application of those sources are made since historical data does not exist. From this analysis of reliability with the construction of block diagrams, tree diagram failure for the calculus of maintainability, availability and for the calculus of safety with the application of Dangers and Risks Identification, whose acronym in Spanish is (IPER). It was figured out three results or final percentages taken semiannually, annually and for a third year. High percentages were obtained not less than 70% because of being new elements and being in an initial stage of functioning. That is why is recommended that the obtained outcomes of the analysis of Reliability, Availability, Maintainability and Safety (RAMS) depends on the assignation of the failure rates and the repairing rate of the components or equipment that conforms part of the lifter system, and have a special care when is necessary to obtain data since through own historical data, external data base or for the expert opinion for a correct calculus of the variables.
