Problem definition: We study the combined value of partial demand visibility and flexible capacity, two hedging mechanisms against demand uncertainty, when signing capacity contracts with temporal commitment. Academic/Practical Relevance: With new technological innovations, short commitment...

Problem definition. We study a point-to-point transportation problem, where the transportation planner can use both shuttles and mobility-on-demand vehicles (MoDs) to serve the incoming random demand of passengers.A natural example is the problem of employee commute, a setting where employers...

In this paper, we explore trade-offs between operational flexibility and operational complexity in periodic distribution problems. We consider the gains from operational flexibility in terms of vehicle routing costs and customer service benefits, and the costs of operational complexity in terms...

Traffic data from a 4-mile long congested rural road in Orinda, California, are used to show that traffic delays and vehicle accumulations between any two generic observers located inside a road section can be predicted from the traffic counts measured at the extremes of the section. The traffic...

The arrival times of vehicles traveling southbound along a two-lane, bi-directional highway were recorded at eight neighboring locations upstream of a bottleneck caused by an oversaturated traffic signal. Cumulative curves constructed from these observations describe completely and in great...

This paper studies a model of community-based healthcare delivery for a chronic disease. In this setting, patients periodically visit the healthcare delivery system, which influences their disease progression and consequently their health outcomes. We investigate how the provider can maximize...

Problem Definition: Cost-effective resource allocation policies are important for public-sector and nonprofit organizations. Yet, for some allocation decisions in this context, quantifying costs is difficult, even impossible. Academic/Practice Relevance: Behavioral researchers have studied the...

Problem definition: Trustworthy partners in procurement and service relationships are an asset. How can organizations discern trustworthy from untrustworthy partners, especially early on, so as to not waste time or resources on bad relationships? Academic/Practical Relevance: Prior studies have...

Purpose The purpose of this paper is to develop a framework to evaluate and assess the performance of the COVID-19 vaccine distribution process that is sensitive to the unique supply-side and demand-side constraints exhibited in the US vaccine rollout. Design/methodology/approach A queuing...
