In this paper we survey work related to queues with interruptions that occur due to many
reasons such as server breakdowns, servers taking emergency breaks, and customers …

This paper investigates the performance of task assignment policies for server farms, as the
variability of job sizes (service demands) approaches infinity. Our results reveal that some …

Motivated by the waiting lines between the US–Canadian border crossings, we investigate a
security-check system with both security and customer service goals. In such a system, every …

When dispatching jobs to parallel servers, or queues, the highly scalable round-robin (RR)
scheme reduces the variance of interarrival times at all queues to a great extent but has no …

In this paper, we explore the effect of cross-training workers in Dual Resource Constrained
(DRC) systems with machines having different mean processing times. By means of queuing …

Size-based routing provides robust strategies to improve the performance of computer and
communication systems with highly variable workloads because it is able to isolate small …

In the context of decision making under explorable uncertainty, scheduling with testing is a
powerful technique used in the management of computer systems to improve performance …

Abstract We study the Task Assignment based on Guessing Size (TAGS) policy in a parallel
and homogeneous server system. The policy parameters are the number of servers h and a …

In a system formed by parallel servers and one dispatcher, we study the Task Assignment
based on Guessing Size (TAGS) policy, an open loop task assignment policy where jobs are …

In manufacturing and services, random problems arise that disrupt normal operations.
Organizations must resolve these problems in a timely and cost-efficient manner—which can …
