In previous research (Koochaki et al. 2011, 2012) we found that CBM remains cost effective in the multicomponent serial system because of the longer time between maintenance activities, but is less effective than ABR in grouping maintenance activities. In this paper we will extend these findings by conducting a simulation and analysis of the influence of maintenance policies on workforce planning and maintenance scheduling. We modelled a threecomponent system into a serial and parallel configuration. We designed experiments for three types of maintenance
resources: (1) no maintenance worker constraints, (2) external maintenance workers with a response time, and (3) a limited number of internal maintenance workers. We also applied opportunistic maintenance. This strategy may improve the occupational rate of maintenance resources when there are resource availability constraints
