Simulation models and some applications to maintenance and repair systems

Simulation is one of the powerful techniques to study maintenance and repair phenomena. Perhaps the most compelling reason for the adoption of simulation has been the need to realistically model a complex environment. Simulation is quite sophisticated in that it enables various groups, activities, and resource mixes to be modelled. Further failure rates of systems and subsystems, repair times and equipment movement times can all be determined randomly based on input probability distributions. Simulation has a distinct advantage to conduct various trade-off studies like trade-offs between manpower requirements and component reliability and their effect on selection from various means.
