A b s t r a c t Queueing network models with finite capacity queues and blocking are used to represent systems with finite capacity resources and with resource constraints, such as production, communication and computer systems. Various blocking mechanisms have been defined in literature to represent the various behaviours of real systems with limited resources. Queueing networks with finite ca...

Queueing systems with server vacations (server’s performing non-queueing jobs) have been studied extensively since the late 70’s. A considerable number of works in this area were completed in the early 80’s and surveyed by Doshi in 1986. As an extension to the classical queueing system, allowing idle servers to work on non-queueing jobs makes the vacation models more applicable in a variety of ...

For advanced packet switches, output queueing has received increased attention owing to its performance advantages. However, practical output queue size limitations may require additional queueing at the inputs. This paper considers a single-stage nonblocking N x N packet switch with both output and input queueing. The limited queueing at the output ports resolves output port contention partial...

background: noise prediction is considered to be the best method for evaluating cost-preventative noise controls in industrial workrooms. one of the most important issues is the development of accurate models for analysis of the complex relationships among acoustic features affecting noise level in workrooms. in this study, advanced fuzzy approaches were employed to develop relatively accurate ...
