We study three problems on supply chain location and inventory under uncertainty. In Chapter 2, we study the inventory purchasing and allocation problem in a movie rental chain under demand uncertainty. We formulate this problem as a newsvendor-like problem with multiple rental opportunities. We...

We analyze the problem of optimal location of a set of facilities in the presence of stochastic demand and congestion. Customers travel to the closest facility to obtain service; the problem is to determine the number, locations, and capacity of the facilities. Under rather general assumptions...

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...

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...

In this paper we study a class of locations models where facilities are not perfectly reliable and failures may be correlated. We analyze problems with Median and Center objectives under complete and incomplete customer information regarding the state of facilities. The goal is to understand how...

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...

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...
