Maintenance Forecasting and Capacity Planning

Carrying out an effective maintenance operation requires efficient planning of maintenance activities and resources. Since planning is performed in order to prepare for future maintenance tasks, it must be based on good estimates of the future maintenance workload. The maintenance workload consists of two major components: (1) scheduled and planned preventive maintenance, including planned overhauls and shutdowns, and (2) emergency or breakdown failure maintenance. The first component is the deterministic part of the maintenance workload. The second component is the stochastic part that depends on the probabilistic failure pattern, and it is the main cause of uncertainty in maintenance forecasting and capacity planning.
