Fleet management in European integration: the case of military helicopter support

The article focuses on both economics and spatial issues related to Maintenance Repair and Overhaul (MRO) of defence platforms in Europe. Using facts and figures related to costs, trends and fleet sizes evolution, the authors discuss the interest of a spatial reorganisation of MRO production. Given the fiscal situation of the main European countries with a modern army, the relevant scale to consider the reorganisation is certainly Europe. Through the example of defence helicopters fleets of a selection of European countries, the authors address the question of cooperation of the MRO. A greater cooperation in the support of fleets would lead to a spatial reorganisation of MRO. On one side economies can be expected from this reorganisation, but, on the other hand, new problems arise. Specifically, a number of costs associated with different forms of “distances” – geographical, operational and political distances – limit the potential savings that could be expected. This work provides insights on these important issues for the construction of a European defence, both in its political, military and industrial dimensions.

Optimal production and maintenance policy for imperfect production systems

A joint optimization of the production run length and preventive maintenance (PM) policy is studied for a deteriorating production system where the in‐control period follows a general probability distribution with non‐decreasing failure rate. In the literature, the sufficient conditions for the optimality of the equal‐interval PM schedule is explored to derive an optimal production run length and an optimal number of PM actions. Nevertheless, an exhaustive search may arise. In this study, based on the assumption that the conditions for the optimality of the equal‐interval PM schedule hold, we derive some structural properties for the optimal production/PM policy, which increases the efficiency of the solution procedure. These analyses have implications for the practical application of the production/PM model to be more available in practice. A numerical example of gamma shift distribution with non‐decreasing failure rates is used to illustrate the solution procedure, leading to some insight into the management process. © 2005 Wiley Periodicals, Inc.
