Steel structures such as bridges, tanks and pylons are exposed to outdoor weathering conditions. In order to prevent them from corrosion they are protected by an organic coating system. Unfortunately, the coating system itself is also subject to deterioration. Imperfect maintenance actions such...

In this paper we verify the conditions under which the marginal cost approch of Berg holds. As observed by Aven and dekker the validity of the marginal cost approch gives rise to useful framework of single component maintenance optimization models which covers almost all models used in practice
