Spatial development plans often aim at defining the level of hierarchy to assign to the urban centers of a region, each level being characterized by a class of facilities. The services provided at the facilities typically include education, health care, public safety, and justice. In this paper...

Spatial planners often make “comprehensive†decisions on the location of public service facilities by using the concept of urban hierarchy: population centers at the upper level of the hierarchy (typically large cities) get the highest level facilities, such as specialized hospitals...

We consider two locations in tandem of an inventory model, so-called the buffer and the store. The content levels in both locations are controlled simultaneously by transferring inventory from the buffer location to the store location. Under a certain cost function that takes into account the...

We consider a coordinated location-inventory model where distribution centers (DCs) follow a periodic-review (R,S) inventory policy and system coordination is achieved by choosing review intervals at the DCs from a menu of permissible choices. We introduce two types of coordination: partial...

A major problem addressed during the preparation of spatial development plans relates to the accessibility to facilities where services of general interest such as education, health care, public safety, and justice are offered to the population. In this context, planners typically aim at...

In this paper we propose a covering problem where the covering radius of a facility is controlled by the decision-maker; the cost of achieving a certain covering distance is assumed to be a monotonically increasing function of the distance (i.e., it costs more to establish a facility with a...
