We define an analytical approach and a methodology to determine the set of Service Level Agreements (SLA) that can be effectively supported by a DiffServ IP network. We consider the Assured Forwarding (AF) Per Hop Behavior (PHB), and, based on the SLA probabilistic description, we derive a worst-case mathematical formulation for the overbooking probability, i.e., the probability that the traffi...

The paper presents a return on quality model designed to assess projects of service quality that can help airlines in retaining passengers. Such models can enable carriers simulate scenarios and assist management in decision-making processes, identifying the elements of performance that can lead to rejection or approval by passengers. An application of the methodology considers the flight firmi...

The challenge of balancing the interests of patients with those of healthcare providers is increased when patients fail to show up for scheduled appointments. Overbooking appointments mitigates the lost productivity caused by no-shows but increases patient wait time and provider overtime. In this paper, simulation analysis is used to develop and test the performance of scheduling rules that are...

OBJECTIVE The urgent nature of head and neck cancer referrals often results in overbooked schedules, access delays, and patient, physician, and staff dissatisfaction. The goal of this study is to examine how incorporation of associate providers (APs) into a head and neck tumor clinic (HNTC) can improve access. METHODS Scheduling data for the Dartmouth-Hitchcock HNTC 2 years prior (January 201...

The extant literature proposes an option-based hedging mechanism for airlines in a parallel alliance to transfer bumped passengers their partner's flight. This paper extends this by conducting strategic analyses and developing two-stage simulation-based algorithm identify the best strategy applying mechanism. Specifically, refers number of options allied carriers transact. authors show that the...

Rising trends in the number of customers turning to the cloud for their computing needs has made effective resource allocation imperative for cloud service providers. In order to maximize profits and reduce waste, providers have started to explore the benefits of oversubscribing cloud resources. However, the benefits of oversubscription in the cloud are not without inherent risks. In this paper...
