Book excerpt: This thesis is concerned with the control of entry of queueing systems. An M/M/1 model with a single class of customers and an infinite time horizon studied by Naor (1969) provides the starting point for this work. Each customer receives a fixed reward for service and pays a holding cost at a fixed rate per unit of time he spends in the system. Each customer may choose to join the system or not. A self-optimizing customer decides whether or not to join by acting to maximize his own expected net benefit. A social optimizing customer decides by acting to maximize the gain rate of the system, the sum of the expected net benefits per unit time of all arrivals. Socially optimal control of the model is provided by establishing a balking point for the customers that is no greater than the balking point a self-optimizing customer would determine. Naor's approach is compared with the semi-Markov decision process formulation of Yechiali (1971). The results for this first model are extended to show that the gain rate can only increase as the arrival rate of the customers increases while the social balking point can only decrease as the arrival rate increases. A semi-Markov approach is used to formulate an expanded model with several classes of customers, each with its own reward and holding cost rate. Socially optimal control of this model is shown to be provided by establishing a balking point for each class that is no greater than the balking point a member of the class would determine if he acted to maximize his own expected net benefit.

Download or read book Fuzzy Control of Queuing Systems written by Runtong Zhang and published by Springer Science & Business Media. This book was released on 2005 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day we experience the annoyance of having to queue. The phenomenon is becoming more prevalent in our increasingly congested and urbanised society. Not only the visible queues in traffic jams, airport check in desks and supermarkets, but the more common invisible queues caused by voice calls and data packets in optical and wireless channels. Queues cost us time, money and resources; so what is the solution to our greater demand for services than there are facilities? Queuing control plays a crucial role in manufacturing and communication networks around the world. This pioneering approach, using fuzzy control to solve queuing control problems, determines explicit solutions to various types of control in queuing systems. The bulk of results have been developed over the past decade and are presented here together for the first time. 21 detailed case studies demonstrate an efficient departure from classical techniques. Unique work creating a new Research and Development topic. Multidisciplinary approach that will benefit researchers and students throughout the fields of artificial intelligence, operations research, optimal control, Internet techniques, communications and traffic control industries. Equipped with an extensive bibliography for easy reference and scope for further study. Existing practical problems, especially those that are unresponsive to conventional control techniques, are solved with the introduction of this novel approach. A systematic framework of the ‘fuzzy control of queuing networks’ is developed through each individual case.

Book Synopsis Price Scheduling in a Time-sharing Queueing System by : J. M. Babad
Download or read book Price Scheduling in a Time-sharing Queueing System written by J. M. Babad and published by . This book was released on 1973 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with a time-sharing system in which users may join after paying an appropriate toll and are subjected to service and waiting charges. The form of an optimal joining policy that minimizes the expected loss of users who may join the system at some of its queues is derived, and is shown to be a control-limit policy with a single control number for every possible entry queue; a newly arriving user will join the minimal-priority entry queue that is not filled up to its contrl number. Tolls and charges that maximize the average expected revenue of the system, as well as the control numbers, are determined for a round-robin time-sharing system. A multi-entrance foreground-background time-sharing system with random entrance is analyzed and the characteristics of the system, such as expected waiting times and expected number of waiting users in each queue, are given. It is shown that when the entry into this system is based on tolls and charges, there exists a set of prices (and associated control numbers) that maximizes the discounted expected revenues of the system.
Book Synopsis Controlled Queueing Systems by : Mikhail Yu. Kitaev
Download or read book Controlled Queueing Systems written by Mikhail Yu. Kitaev and published by CRC Press. This book was released on 1995-08-30 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book completely devoted to controlled queueing systems. The book gathers the newest results of the theory of Markov decision processes related to queueing models and demonstrates their applications to main types of control in queueing systems, including control of arrivals, control of service mechanism, and control of service discipline. Emphasis is placed on conditions providing further "good" structural properties of Markov optimal strategies such as monotonicity, threshold or hysteretic character, and priority. Each chapter is followed by exercises, most of which allow the reader to complete technical fragments of proofs. The text assumes the reader is familiar with standard courses of analysis, probability theory, and queueing theory.

Book Synopsis Control Mechanisms in Queueing Systems with Nonlinear Waiting Costs by : Ata Ghareh Aghaji Zare
Download or read book Control Mechanisms in Queueing Systems with Nonlinear Waiting Costs written by Ata Ghareh Aghaji Zare and published by . This book was released on 2017 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many queueing systems, customers have been observed to exhibit strategic behavior. Each customer gains a value when receiving a product or getting served and suffers when incurring a delay. We consider a nonlinear waiting cost function to capture the sensitivity of customers toward delay. We investigate customers' behavior and system manager's strategy in two different settings: (1) customers are served in a service system, or (2) they receive a product in a supply chain. In the first model, we study an unobservable queueing system. We consider that customers are impatient, and are faced with decision problems whether to join a service system upon arrival, and whether to remain or renege at a later time. The goal is to address two important elements of queueing analysis and control: (1) customer characteristics and behavior, and (2) queueing control. The literature on customer strategic behavior in queues predominately focuses on the effects of waiting time and largely ignores the mixed risk attitude of customer behavior. Empirical studies have found that customers' risk attitudes, their anticipated time, and their wait time affect their decision to join or abandon a queue. To explore this relationship, we analyze the mixed risk attitude together with a non-linear waiting cost function that includes the degree of risk aversion. Considering this behavior, we analyze individuals' joint balking and reneging strategy and characterize socially optimal strategy. To determine the optimal queue control policy from a revenue-maximizer perspective, which induces socially optimal behavior and eliminates customer externalities, we propose a joint entrance-fee/abandonment-threshold mechanism. We show that using a pricing policy without abandonment threshold is not sufficient to induce socially optimal behavior and in many cases results in a profit lower than the maximum social welfare the system can generate. Also, considering both customer characteristics and queue control policy, our findings suggest that customers with a moderate anticipation time provide higher expected revenue, acknowledging the importance of understanding customer behavior with respect to both wait time and risk attitude in the presence of anticipation time. In the second model, we consider a two-echelon production inventory system with a single manufacturer and a single distribution center (DC) where the manufacturer has a finite production capacity. There is a positive transportation time between the manufacturer and the DC. Each customer gains a value when receiving the product and suffers a waiting cost when incurring a delay. We assume that customers' waiting cost depends on their degree of impatience with respect to delay (delay sensitivity). We consider a nonlinear waiting cost function to show the degree of risk aversion (impatience intensity) of customers. We assume that customers follow the strategy p where they join the system and place an order with probability p. We analyze the inventory system with a base-stock policy in both the DC and the manufacturer. Since customers and supply chain holder are strategic, we study the Stackelberg equilibrium assuming that the DC acts as a Stackelberg leader and customers are the followers. We first obtain the total expected revenue and then derive the optimal base-stock level as well as the optimal price at the DC.
