In this paper we study different maintenance policies for the control of production systems that are subject to deterioration over time. A Markov model is used to characterize the deterioration process. Two types of basic maintenance policies are considered: scheduled preventive maintenance and...

Inspection policy models describe stochastically failing systems in which failures are detected by inspections only. We develop such an inspection model for a production facility. The model generalizes the recent work of Munford as well as the classical work of Barlow et al. Revenues are accrued...

A number of jobs have to be carried out on a gas transmission network every year, which restrict the transmission capacity of the network while they are in progress. There are certain pairs of jobs which must not be in progress at the same time. The network must meet a convex annual demand...
