A reliability analysis of 8hp-pml gold engine coupled locally fabricated cassava grinding machine

Abstract

This work models the failure rate of an 8HP-PML Gold Engine coupled locally fabricated cassava grinding machine whose operational efficiency degrades with time and usage to obtain its performance measures. The failure distribution of the machine was shown to follow a Weibull distribution with shape parameter, and scale parameter, . Some probability functions of the machine such as the failure density function, failure distribution function, the reliability function and the hazard function were obtained. Also, reliability indices obtained for the machine shows that the cassava grinding machine is in a good and sustainable working condition. These include; the mean time to repair (MTTR=99 hours), the mean time between failure (MTBF = 4190 hours) and the availability factor, A = 97.7% while the maintainability factor is M=2.3%.
