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...

A Markovian line with changed fix and state subordinate section rate has been analyzed. The probability creating limit of the line gauge at an abstract time is procured using favorable variable framework. Some huge introduction estimates like expected line gauge, foreseen length of dormant and...

The usual negative effect of queue size on arrival to an M/M/c service facility is augmented, in this paper, by the negative network effect due to waiting with others, which increases as the exposure to others increases. The reward and cost structure acquires a new meaning, as the cost of...

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...
