Moment Analysis for Closed Queuing Networks and its Linearizer
Closed product-form queueing networks are considered. Mean value analysis is further developed to become "moment analysis", a recursive evaluation schema for moments of the queue lengths and customers' sojourn times at FCFS centers. As with mean value analysis, in general no state probabilities are needed. Moment analysis can be approximately done by an extended Linearizer algorithm.
متن کاملPerfect sampling for closed queuing networks
In this paper we investigate coupling from the past (CFTP) algorithms for closed queuing networks. The stationary distribution has a product form only in a very limited number of particular cases when queue capacity is finite, and numerical algorithms are intractable due to the cardinality of the state space. Moreover, closed networks do not exhibit any monotonic property enabling efficient CFT...
متن کاملA Parametric Decomposition Based Approach for Multi-class Closed Queuing Networks with Synchronization Stations
Multi-class closed queuing networks with synchronization stations find applications in analytical models of assembly systems and production systems operating under pull control policies. These queuing networks are hard to analyze exactly and therefore approximation methods must be used for performance evaluation. In this research we propose a new efficient approach based on parametric decomposi...
متن کاملAn Extension of Moore's Result for Closed Queuing Networks
In this communication, Moore's result for the normalization constant of a closed queuing network of exponential servers is extended to the case of nondistinct traffic intensities. We then show that this result can be applied to various more general closed and semiclosed queuing networks with a product-form solution. Introduction Substantial progress has been made recently in extending the scope...
متن کاملMultivariate Rational Approximants for Multiclass Closed Queuing Networks
ÐClosed Markovian networks of queues with multiclass customers and having a product form equilibrium state probability distribution are useful in the performance evaluation and design of computer and telecommunication systems. Therefore, the efficient computation of the normalizing function, the key element of the solution in product form, has attracted considerable effort. We consider a networ...
