It is a standard practice for cloud service providers (CSPs) to overbook physical system resources to maximize the resource utilization and make their business model more profitable. Resource overbooking can, however, lead to performance interference between the virtual machines (VMs) hosted on the physical resources thereby causing performance unpredictability for applications hosted in the VM...

It is standard practice for cloud service providers (CSPs) to overbook physical system resources to maximize the resource utilization and make their business model more profitable. Resource overbooking can lead to performance interference, however, among the virtual machines (VMs) hosted on the physical resources causing performance unpredictability for soft real-time applications hosted in the...

We construct several models to examine the effect of overbooking policies on airline revenue and costs in light of the current state of the industry, including fewer flights, increased security, passengers’ fear, and billions in losses. Using a plausible average ticket price, we model the waiting-time distribution for flights and estimate the average cost per involuntarily bumped passenger. For...

Hotels cooperate with third-party websites to enhance their competitive position and attain sustainable development in the era of e-commerce. Furthermore, hotel managers overbook to hedge against last-minute cancellations and customer no-shows. This paper discusses pricing and overbooking strategies of a hotel in the context of cooperation with multiple third-party websites and analyzes how the...

10 Clinical overbooking is intended to reduce the negative impact of patient no-shows on clinic op11 erations and performance. In this paper, we study the clinical scheduling problem with overbooking 12 for heterogeneous patients, i.e. patients who have different no-show probabilities. We consider the 13 objective of maximizing expected profit, which includes revenue from patients and costs ass...

This paper analyzes the effect of overbooking for scheduling systems in a commercial environment. In this scenario each job is associated with a release time and a finishing deadline as well as a fee for a successful execution and a penalty for violating the deadline. The core idea is to exploit overestimations of required job execution times, providing an opportunity to aggressively schedule a...

As Grid and P2P computing become more and more popular, many schedule algorithms based on economics rather than traditional pure computing theory have been proposed. Such algorithms mainly concern balancing resource supply and resource demand via economic measures. As we know, fairness and efficiency are two conflicting goals. In this paper, we argue that overbooking resources can greatly impro...

OBJECTIVE To find the causes of operating room cancellation in patients attending preoperative anaesthesia clinic and scheduled for surgery at our institution. METHODS This audit included all those patients who presented to the pre anaesthesia clinic with their surgeries planned in the main operating rooms of our hospital. The duration of this audit was two months. Cancelled cases were identi...
