摘要:The process of manually constructing monthly working schedules for physicians in medium-sized and large departments at hospitals is a very time-consuming and error-prone task. The scheduler, typically a senior physician, is an expensive resource and oftentimes almost irreplaceabl...

摘要:The only therapy for patients with end-stage liver disease is transplantation. In order to be eligible for a cadaveric liver transplantation in the United States, a patient must join a waiting list maintained by the United Network for Organ Sharing System, which allocates li...

摘要:Women’s College Hospital (WCH) in Toronto, Canada, offers roughly 300 outpatient clinics every week. In April 2011, we started working with WCH to design a new schedule for their clinics, to accommodate a move to a new hospital building that was completed in May 2013. We dev...

摘要:Markdown as a pricing modality is ubiquitous in retail whereas everyday low price (EDLP) remains relatively rare (despite its several advantages, such as simplicity). This paper explores whether and why retailers can use either of these pricing modalities as an effective def...

摘要:We study a model of two-player, zero-sum, stopping games with asymmetric information. We assume that the payoff depends on two independent continuous-time Markov chains, where the first Markov chain is only observed by player 1 and the second Markov chain is only observed by play...

摘要:This paper addresses the stochastic user equilibrium (SUE) in the case where the route choice is the multinomial logit model (MNL). Our main finding is that MNL SUE can be formulated and solved as an immediate extension of the deterministic user equilibrium (DUE) through a p...

摘要:Telemedicine services are increasingly being used to provide medical care to patients in rural areas. We present a two-stage stochastic linear program to inform optimal scheduling of telemedicine patients considering cleaning of procedure devices and patient no-show behavior. We ...

摘要:The vertex cover problem is one of the most important and intensively studied combinatorial optimization problems. Khot and Regev [Khot S, Regev O (2008) Vertex cover might be hard to approximate to within 2 − ɛ . J. Comput. System Sci. 74(3):335–349] proved that the pr...

摘要:This paper presents a new approximation formula for pricing multidimensional discretely monitored average options in a local-stochastic volatility (LSV) model with jump by applying an asymptotic expansion technique. Moreover, it provides a justification of the approximation metho...
