This paper presents a linear reliability-based model as an extension of the well-known linear location set covering problem (LSCP) for emergency service vehicles such as ambulances. Linear programming models have a practical advantage over other nonlinear or queuing-based models. They can be...

In this paper we describe the successful application of a sophisticated Operations Research model and the corresponding solution techniques for scheduling the 6,500+ drivers and conductors of the Dutch railway operator NS Reizigers (Netherlands Railways). In 2001 the drivers and conductors were...
