Multiserver queueing systems in heavy traffic
In the study of queueing systems, a question of significant current interest is that of large scale behavior, where the size of the system increases without bound. This regime has becoming increasingly relevant with the rise of massive distributed systems like server farms, call centers, and health …

Large deviation theory for queueing systems
… with a nonnegative state space as a model for a queueing system. The motivation of this study is about useful estimates of system performance. For example, in a system with finite queues, the probability of the system of queues going from an empty state to a state in which the population of at …

Large scale queueing systems : asymptotics and insights
… in a variety of applications, including service systems and telecommunication networks. A particular application that has received considerable attention in recent years is the analysis of call centers. A feature common to these models is the notion of the 'trade-off' between quality and …

Access size and order in queueing systems
General queueing systems are discussed in order to familiarize the reader with the problem. Various access arrangements including straight, graded, slipped, and random access multiples are discussed and compared. Blocking probability curves for slipped multiple access order are generated. Cost of …

Staffing queueing systems with cyclical demand and unreliable servers
… (SIPP) method for staffing a multi-server delay queueing system with time-varying demand and server absence. Using the M(t)/M/c(t) queueing model, we systematically examine the SIPP method across various scenarios, including realistic ones, considering cyclical customer arrival rates and multiple …

Algorithmic issues in queueing systems and combinatorial counting problems
(cont.) However, these randomized algorithms can never provide proven upper or lower bounds on the number of objects they are counting, but can only give probabilistic estimates. We propose a set of deterministic algorithms for counting such objects for three classes of counting problems. They are …

Problems in feedback queueing systems with symmetric queue disciplines
In this paper we study properties of a queue with instantaneous Bernoulli feedback where the service discipline is one of two symmetric disciplines. For the processor sharing queue with exponentially distributed service requirements we analyze the departure process, imbedded queue lengths, and the …

Control of multiclass queueing systems with abandonments and adversarial customers
… model the surveillance scenario as a multiclass queueing system with customer abandonments, wherein the operational problem translates into developing service policies for a server in order to minimise the expected damage an adversarial customer can inflict on the system. We consider three …

Extended Entropy Maximisation and Queueing Systems with Heavy-Tailed Distributions
Numerous studies on Queueing systems, such as Internet traffic flows, have shown to be bursty, self-similar and/or long-range dependent, because of the heavy (long) tails for the various distributions of interest, including intermittent intervals and queue lengths. Other studies have addressed …

Guidelines for the design of flexibility in queueing systems : model, measures, and analysis
… in revenue management techniques for operational systems, we show that such operational control policies can have disproportionate influence on revenue and cost measures of performance; this fact further underscores the importance of having such models, measures, and analytical tools to examine …

Analysis of Alternative Queue Systems in Simulated Amusement Parks
… seeks to analyze the effects of alternative queueing systems on guest welfare in amusement parks. Many parks have implemented these systems, allowing some guests to skip the traditional lines for attractions. This project entailed building an amusement park simulation system, permitting …

Approximate solutions for multi-server queuing systems with Erlangian service times and an application to air traffic management
… of certain M(t)/G(t)/n(t)/n(t) + q queueing systems. More specifically, we are interested in such systems under very general conditions such as time-varying demand and capacity, and high utilization, including occasional oversaturation. Conditions such as these cannot be addressed …

Applications of robust optimization to queueing and inventory systems

Analysis of a feed-forward priority queueing system
… the problem of analyzing feed-forward priority queueing systems. In this type of system incoming units enter one of n priority queues if the service facility is busy. Units in the highest priority queue are served on a first-come-first-served basis while units in the lower priority queues will …
