ObjectivesThe objective was to derive and validate a novel queuing theory–based model that predicts the effect of various patient crowding scenarios on patient left without being seen (LWBS) rates.MethodsRetrospective data were collected from all patient presentations to triage at an urban,...

Hospital emergency departments (EDs) typically rely on central laboratories to analyze patient samples for the purposes of diagnosing and treating patients. Point-of-care testing (POCT) is a process redesign that shifts the analysis of samples from the central lab to the ED. Using a queueing...

This paper studies a supply contracting problem where a buyer sources a product from a supplier to satisfy uncertain market demand. With the increasing length and complexity of today's global supply chains, the buyer may face two issues when designing the supply contract: adverse selection...

Problem definition: This paper studies an entrepreneur's pricing strategy in a reward-based crowdfund-ing campaign under asymmetric product quality information. We propose two signaling mechanisms and investigate the relative performance of these mechanisms under different market...

This paper studies the optimal component procurement strategies of two competing OEMs selling substitutable products. The OEMs outsource their production to a common contract manufacturer, who in turn needs an input from a component supplier. Each OEM may either directly procure the input from...

This paper explores the merits of hedging stochastic input costs (i.e., reducing the risk of adverse changes in costs) in a decentralized, risk neutral supply chain. Specifically, we consider a generalized version of the well-known ‘selling-to-the-newsvendor' model in which both the up-stream...
