This paper studies the efficiency of two subsidy schemes widely used in health-care systems: unconditional and conditional. Unconditional schemes partially subsidize customers seeking private care without pre-requirement, whereas conditional schemes fully subsidize those who have waited...

We consider a service market with two firms that provide regular and premium services respectively. Customers are delay sensitive and heterogeneous on evaluating the service level. We show that the service differentiation, together with customer heterogeneity, results in market segmentation...

This paper considers a monopoly firm (carrier) that charges a uniform price to passengers. Passengers are delay-sensitive and hence demand rates depend on waiting times. The carrier can choose to reveal or hide waiting time information. We show that optimal information strategies depend on the...

This paper aims to examine and design operational strategies for mixed flows of autonomous vehicles (AVs) and human-driven vehicles (HVs). Unlike HV drivers who are heterogeneous in driving behaviors, AVs are expected to make optimal driving controls and improve mobility in platoons. Moreover,...

We consider two balking queue models with different types of information about delays. Potential customers arrive according to a Poisson process, and they decide whether to stay or balk based on the available delay information. In the first model, an arriving customer learns a rough range of the...
