Optimal Server Allocation in General, Finite, Multi-Server Queueing Networks

چکیده
Queueing networks with finite buffers, multiple servers, arbitrary acyclic, series-parallel topologies, and general service time distributions are considered in this paper. An approach to optimally allocate servers to series, merge, and split topologies and their combinations is demonstrated. The methodology builds upon two-moment approximations to the service time distribution embedded in the generalized expansion method for computing the performance measures in complex finite queueing networks and Powell’s algorithm for optimally allocating servers to the network topology. Convexity of the objective function along with results from computational experiments are presented for showing the efficacy of the methodology.

Buffer allocation in general finite multi-server queuing networks
We address in this paper the buffer allocation problem in general service, finite waiting room, multi-server queueing networks. Several instances are examined using an approximation method to estimate the performance of the queueing networks and an iterative search method is developed to find the optimal buffer allocation within the network. The coefficient of variation of the service time is s...

This paper analyzes a discrete-time $Geo/Geo/c$ queueing system with multiple working vacations and reneging in which customers arrive according to a geometric process. As soon as the system gets empty, the servers go to a working vacations all together. The service times during regular busy period, working vacation period and vacation times are assumed to be geometrically distributed. Customer...
متن کاملOn Two-Echelon Multi-Server Queue with Balking and Limited Intermediate Buffer
In this paper we study two echelon multi-server tandom queueing systems where customers arrive according to a poisson process with two different rates. The service rates at both echelons are independent of each other. The service times of customers is assumed to be completed in two stages. The service times at each stage are exponentially distributed. At the first stage, the customers may balk ...
