The effect of maintenance activities on the component of a system could either be perfect or imperfect. A perfect maintenance implies that the condition of the component is as good as new while imperfect implies that its condition has improved to a certain degree. Real engineering system problems in this domain usually consist of components with varying maintenance policies; perfect and imperfect. It is usually easier to optimise or analyse a system when subjected to homogeneous preventive maintenance (PM) policy; either solely perfect or imperfect. This paper investigates the optimisation of a heterogeneous (both perfect and imperfect) PM policy by using respective evaluation models and establishing a variant of the non-dominated sorting genetic algorithm (NSGA) II for the problem.
