We aim to structure the maintenance policy selection process for ships, using the Analytic Hierarchy Process (AHP). Maintenance is an important contributor to reach the intended life-time of capital technical assets, and it is gaining increasing interest and relevance. A maintenance policy is a policy that dictates which parameter
triggers a maintenance action and it appears that selecting the right maintenance policy is a difficult group decision. To investigate maintenance policy selection (MPS), we use an eight stage method to structure the multiple criteria decision making process, and build on previous research to propose a refined decision hierarchy, aiming for a structured abstraction of MPS to reveal the core of the MPS problem. After a
preliminary MPS session, this decision hierarchy is applied at a multi-company MPS session, where a group of companies from the same maintenance chain is present. We conclude that the chosen methodology, using our previous results as a starting point, greatly improves the workability of the decision hierarchy. Also, it turns out that discussing the exact meanings of the criteria plays a crucial role in the group decision process.
