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...

Waiting lists offer agents a choice between types of items with associated nonmonetary prices given by required waiting times. These nonmonetary prices are endogenously determined by a tâtonnement-like price discovery process: an item's price increases when an agent queues for it, and decreases...

The attention paid to energy consumption is growing steadily, due to the costs associated with energy usage as well as the resulting environmental impacts. This work proposes an analytical method to assess the energy consumption and the power requirements of a productive system. By exploiting...

Problem definition: The cost of completing a line—a continuous variable—is typically studied indirectly through customers’ decisions to balk or renege from a queue—binary variables. However, these decisions only tell us whether a customer’s completion cost is above some (unknown)...

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...

To study the effect of congestion on the fundamental trade-off between diagnostic accuracy and speed, we empirically test the predictions of a formal sequential testing model in a setting where the gathering of additional information can improve diagnostic accuracy, but may also take time and...

Problem definition: Emergency department (ED) delay announcement systems are implemented in many countries. We answer three important questions pertaining to the operations and effectiveness of such systems by studying the public hospital network and ED waiting time (WT) announcement system in...

Objective: The objective of this paper is to study behavioral analysis of a working system in paper industry for system parameters by modeling using RPGT and taking Particular cases. Methods/Statistical analysis: The state diagram of system is taking into account all probabilities...

Waiting involves both cognition and emotions. It has a bearing on the overall perception of retail service quality. The advancement in retailing has triggered scholarly conversations on the psychological impact of waiting at the retail checkout. Prior studies confirm customers being deeply...
