Queueing Problems with Two Parallel Servers
A group of agents are waiting for their job to be processed in a facility. We assume that each agent needs the same amount of processing time and incurs waiting costs. The facility has two parallel servers, being able to serve two agents at a time. We are interested in finding the order to serve agents and the (positive or negative) monetary compensations they should receive. We introduce two r...
متن کاملVacation model for Markov machine repair problem with two heterogeneous unreliable servers and threshold recovery
Markov model of multi-component machining system comprising two unreliable heterogeneous servers and mixed type of standby support has been studied. The repair job of broken down machines is done on the basis of bi-level threshold policy for the activation of the servers. The server returns back to render repair job when the pre-specified workload of failed machines is build up. The first (seco...
متن کاملOptimal Control of a Queueing System with Three Heterogeneous Servers
We study the problem of optimally controlling a three server queueing system. Arriving customers join a single queue, which is served by three servers, 8 1 , 52 and 53. The servers are exponential, but of different rates. The total expected time a customer spends in the system is to be minimized. We show that the optimal policy can be characterized by three thresholds, m3,mb and mi, such that: ...
متن کاملRouting in a queueing system with two heterogeneous servers in speed and in quality of resolution
Heterogeneous servers, in manufacturing and service systems, may have different speeds and different quality levels for the provided service or good. For a two-server queueing model, we formulate the job routing problem for minimizing the long-run weighted sum of the expected time spent in the system and the throughput of unsatisfied customers. Using a Markov decision process approach, we prove...
متن کاملControlled Queueing Systems with Heterogeneous Servers
Many real-life phenomena, such as computer systems, communication networks, manufacturing systems, supermarket checkout lines as well as structural military systems can be represented by means of queueing models. Looking at queueing models, a controller may considerably improve the system’s performance by reducing queue lengths, or increasing the throughput, or diminishing the overhead, whereas...
