Method Of Predicting, Estimating And Improving Mean Time Between Failures In Reducing Reactive Work In Maintenance Organization

Mean time between failures (MTBF) is a simple way of quantifying a repairable system, subsystem, or component’s reliability. MTBF has been used for various decisions. Reliability of the system quantitatively determines by MTBF. The mathematical approach in quantifying MTBF is being used. Poisson distribution, Weibull model and Bayesian are the most popular approach used in developing the MTBF model. MTBF is often confused with the mean time to failure (MTTF), which MTTF applies to replaceable, rather than repairable. In the current situation, most products designed as the non-repairable unit thus will eliminate varies level of repairing quality due to human error or level of competencies. This paper will explain the underlying complexities and misconceptions of MTBF and clarify in sequence what are the items and concerns that need to be considered in estimating MTBF.
