Many maintenance decisions require the evaluation of alternative solutions in terms of complex maintenance criteria such as cost, repairability, reliability and availability requirements. Such problems can be formulated as multi-criteria decision making problems. The relative importance of maintenance criteria is difficult to be assessed, and therefore a sensitivity analysis becomes a necessity. The sensitivity analysis approach presented in this paper reveals some counter-intuitive results and can considerably enhance the application of decision analysis in complex maintenance management.

Key Words:
Maintenance, decision analysis, multi-criteria decision making, analytic hierarchy process (AHP), sensitivity analysis.
