Networks of Queues Models with Several Classes of Customers and Exponential Service Times
Manuel Alberto M. Ferreira
The main target of this paper is to present the Markov chain C that, not giving explicitly the queue lengths stationary probabilities, has the necessary information to its determin…
Stochastic Processes in Networks of Queues with Exponential Service Times and only one Class of Customers
Manuel Alberto M. Ferreira
Two networks of queues models, presented initially by Jackson, in the open case, and Gordon and Newell, in the closed case, stochastic processes are presented and studied in some o…
Infinite Servers with Poisson Arrivals Queue Busy Period with PME Distribution
Manuel Alberto M. Ferreira
In this article it is shown that if the busy period of a MGinf queue system is PME distributed, the service time is a random variable with a long tail distribution. The result is o…
Studying Pensions Funds Through an Infinite Servers Nodes Network: A Theoretical Problem
Manuel Alberto M. Ferreira, Marina Andrade, José António Filipe
This study intends to present a representation of a pensions fund through a stochastic network with two infinite servers nodes. With this representation it is allowed to deduce an…
The Age or Excess of the MGinf Queue Busy Cycle Mean Value
Manuel Alberto M. Ferreira, Marina Andrade, José António Filipe
In this work, approximate and exact results concerning a performance measure of the MGinf system, the age or the excess of the busy cycle, are presented. It will be seen that it is…
Some notes on a semi-Markov matrix occurring in the MMinf queue parameters study
Manuel Alberto M. Ferreira
The main objective of this work is to present a process to compute the Markov renewal matrix for Markov renewal processes with countable infinite spaces, which semi-Markov matrixes…
QUEUE, with Poisson arrivals, constant service time and infinite servers, BUSY PERIOD DISTRIBUTION
Manuel Alberto M. Ferreira
The queue system,with Poisson arrivals,constant service time and infinite servers, busy period distribution is intensively studied because, due to its probability density function…
