Book Synopsis Optimal Control of Non-Conventional Queueing Networks by : Xiaoting Chen
Download or read book Optimal Control of Non-Conventional Queueing Networks written by Xiaoting Chen and published by . This book was released on 2015 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers stochastic modeling and optimization problems associated with a type of queueing network later defined as non-conventional queueing networks. Unlike their conventional counterparts, where only external arrival and service-related dynamics in the networks are modeled, non-conventional queueing networks not only admit general inter-arrival and service time distributions but also allow the modeling of other types of recurring events within a network. As a result, a non-conventional queueing network becomes much more appropriate for modeling realistic systems. For queueing networks, one of the main research problems is to find a good control policy so that networks can work within stable and ecient regions. In this study, we consider one of these problems, known as sequencing control, which involves prioritizing waiting customers or jobs in the network so that the overall throughput of the network can be improved. To optimize sequencing control problems in non-conventional queueing networks, an analytic and tractable approach is needed. To achieve this, a model approximation method based on the use of phase-type (PH) distributions is investigated in this study. Here, the use of PH distributions admits a tractable Markov model of the problem so that an optimization problem can be associated with the network. One then attempts to solve this optimization problem and hopes that an optimal solution can be obtained for the corresponding network. This is not quite true, as there usually exist certain mismatches between the real process and its approximated mathematical model. These mismatches would generally suggest two types of model parameter uncertainties with the problem. The first type can be associated with the problem's cost structure in reflecting correct objectives for the problem to be optimized, and the second type can be associated with the underlying parameters of the model in reflecting the correct dynamics of the process, e.g., the transition matrix. In particular, the latter type can be often incurred during the model approximation steps. Three practical challenges are then identified in this work with model approximation steps for nonconventional queueing networks, corresponding to 1) simultaneous approximation, 2) event concurrency, and 3) state space expansion. It is also found that the first two challenges will usually lead to biases or deviations in the underlying model parameters and thus create parameter uncertainties. This becomes even more severe when model approximation is carried out with higher-order moment-matching algorithms. The last challenge raises the classic computational tractability issue, known as the "curse of dimensionality." To overcome these challenges and ameliorate the effects of model parameter uncertainties, a heuristic solution is proposed and investigated in this work. This heuristic approach is based on the use of what we call a nominal-optimal policy set. To proceed with the development of this heuristic approach, optimality equations and structural properties for optimal sequencing control problems are first presented and discussed. These results are utilized later, along with proper parameterization of the problem's cost structure, to help explore and evaluate dierent control policies. To further facilitate and promote this approach, an integrated framework called the extended actor-critic is presented, with the main focus and discussion on its structural and convergence properties. Later, numerical studies and results are also presented and discussed to validate the use of this framework.
Book Synopsis A New Approach for Solving Simultaneous Resource Possession Problems in Closed Queueing Networks by : Darral J. Freund
Download or read book A New Approach for Solving Simultaneous Resource Possession Problems in Closed Queueing Networks written by Darral J. Freund and published by . This book was released on 1982 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new approximate technique is presented for analyzing closed queueing networks with simultaneous resource possession. It is an analytic noniterative solution procedure that is suitable for multiple entry systems such as I/O (input output) models. It relies on solving a closed queueing network consisting only of the subsystem with simultaneous resource possession, where queues can have service rates that are a function of the utilization of all the queues (number of busy servers). The submodel is solved using a newly discovered product form solution. Results are compared with simulation models and other available analytic techniques.

Download or read book Approximated techniques for solution of with markovian closed queues written by and published by . This book was released on 1911 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho tem como objetivo o desenvolvimento de um método aproximado para solucionar modelos de redes fechadas de filas Markovianas com solução do tipo forma produto. O ponto de partida é a representação integral da constante de normalização G. Este enfoque foi usado pela primeira vez pro Mitra, et al., sendo que o método ora proposto é conceitualmente muito mais simples. Como decorrência, o espaço de memória ocupado pelo programa e pelas variáveis fica muito reduzido, além do tempo de processamento ser extremamente pequeno, mesmo quando são usados micro-computadores de oito bits. Uma característica importante da abordagem feita, é que a complexidade do modelo analítico depende somente do número de estações e não da quantidade de classes e nem da população.

Book Synopsis Performance Modeling for Computer Architects by : C. M. Krishna
Download or read book Performance Modeling for Computer Architects written by C. M. Krishna and published by John Wiley & Sons. This book was released on 1995-10-14 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: As computers become more complex, the number and complexity of the tasks facing the computer architect have increased. Computer performance often depends in complex way on the design parameters and intuition that must be supplemented by performance studies to enhance design productivity. This book introduces computer architects to computer system performance models and shows how they are relatively simple, inexpensive to implement, and sufficiently accurate for most purposes. It discusses the development of performance models based on queuing theory and probability. The text also shows how they are used to provide quick approximate calculations to indicate basic performance tradeoffs and narrow the range of parameters to consider when determining system configurations. It illustrates how performance models can demonstrate how a memory system is to be configured, what the cache structure should be, and what incremental changes in cache size can have on the miss rate. A particularly deep knowledge of probability theory or any other mathematical field to understand the papers in this volume is not required.
