Background and Objectives: Operating rooms (ORs) are precious resources in hospitals, as they constitute more than 40% of the hospital revenues.As such, surgical cancellations are very costly to hospitals. Same-day surgery cancellations or no-shows were found to be the main contributing factor to underutilization of operating rooms (ORs) in a public-sector hospital despite the ...

Experience-based admission control (EBAC) is a hybrid approach combining the classical parameter-based and measurement-based admission control. EBAC calculates an appropriate overbooking factor used to overbook link capacities with resource reservations in packet-switched networks. This overbooking factor correlates with the average peak-to-mean rate ratio of all admitted traffic flows on the l...

Following the successful stories in the airline industry, many primary-care clinics have adopted overbooking to deal with their prevalent patient no-show problem. However, there has been very limited research, to the best of our knowledge, that analyzes the impact of overbooking on the major causes/factors of patient no-show and its implications. While overbooking has little impact on many rand...

The problem of patient no-shows (patients who do not arrive for scheduled appointments) is significant in many health care settings, where no-show rates can vary widely. No-shows reduce provider productivity and clinic efficiency, increase health care costs, and limit the ability of a clinic to serve its client population by reducing its effective capacity. In this article, we examine the probl...

We consider optimal pricing policies for airlines when passengers are uncertain at the time of ticketing of their eventual willingness to pay for air travel. Auctions at the time of departure efficiently allocate space and a profit maximizing airline can capitalize on these gains by overbooking flights and repurchasing excess tickets from those passengers whose realized value is low. Neverthele...

Cloud service providers (CSPs) often overbook their resources with user applications despite maintaining service-level agreements with their customers. Overbooking is attractive to CSPs because it helps to reduce power consumption in the data center by packing more user jobs in less number of resources while improving their profits. Overbooking becomes feasible because user applications tend to...

The commercial exploitation of the emerging Grid and Cloud markets needs SLAs to sell computing run times. Job traces show that users have a limited ability to estimate the resource needs of their applications. This offers the possibility to apply overbooking to negotiation, but overbooking increases the risk of SLA violations. This work presents an overbooking approach with an integrated risk ...

Experience-based admission control (EBAC) is a hybrid approach combining the classical parameter-based and measurement-based admission control schemes. EBAC calculates an appropriate overbooking factor used to overbook link capacities with resource reservations in packet-based networks. This overbooking factor correlates with the average peak-to-mean rate ratio of all admitted traffic flows on ...

This paper considers an overbooking problem with multiple reservation and inventory classes, in which the multiple inventory classes may be used as substitutes to satisfy the demand of a given reservation class (perhaps at a cost). The problem is to jointly determine overbooking levels for the reservation classes, taking into account the substitution options. Such problems arise in a variety of...
