Reliability and Availability Analysis of Mining Systems with Human-Error

Abstract

This study presents reliability and availability analysis of mining systems with hardware and human-error failures. The failures of proposed models representing the mining systems could be safe or unsafe. To understand model reliability and availability behaviours, different values of failure and repair rates were used at different number of parallel units and different repair policies. Also, a model with partial and complete failures was analysed beside two miscellaneous models representing systems used in mining sector. The failure and repair rates are assumed constant. Markov method was used to perform analysis of the models and Laplace transforms were used to solve associated equations.
