This paper considers a two-sided dynamic matching market where agents arrive at the market randomly. An arriving agent is immediately matched if there are agents waiting on the other side. Otherwise, the arriving agent has to decide whether to leave the market and take her outside option or to...

The requirement of social distancing during the COVID-19 pandemic has presented significant challenges for high-rise buildings, which heavily rely on elevators for vertical transportation. In particular, the need for social distancing has reduced elevator capacity typically by at least...

Motivated by empirical studies on the impact of information on abandonment in service systems, we study novel queueing models with abandonment rates that depend on the system state and the granularity of customers’ state information.We consider a two-class multi-server priority queue with...

We study an inventory system with multiple supply sources and expediting options. The replenishment lead times from each supply source are stochastic, representing congestion and disruption. We construct a family of smart ordering and expediting policies that utilize real-time supply...

Queues are common phenomenon in different operations nowadays. This is due to the higher demand for a service compared to the supply. The high demand for the use of the banking sector has posed some significant problems which includes poor service facilities and delivery which remains an...

We consider a learning variant of a canonical scheduling problem in a multiclass many server queue with abandonment (specifically, the M_t/M/N+M and the GI/GI/N+GI queues). The objective is to minimize the long-run average class-dependent expected linear holding and abandonment costs when the...
