Priority Single-Server Queuing System with Optional Second Server Activated upon Request - Simulation Study

Popis výsledku v původním jazyce

Queueing systems with priorities can often be met in practice - e.g. in healthcare or transport. These systems are specific in that there are at least two classes of customers, while priorities are defined for individual classes of customers, according to which customers are served - the priority can be non-preemptive (higher priority customers do not interrupt the service of a lower priority customer) or preemptive-resume (higher priority customers interrupt the service of a lower priority customer). In this paper, we focus on a queueing system with three classes of customers, where the first class has the highest priority and the last third class has the lowest priority. By default, individual customers entering the system are served by single server. However, if a situation arises where the queue length of non-priority customers exceeds a certain defined threshold, it is possible to activate a second parallel server, which helps with serving the lower priority customers. The article describes the simulation model of this queueing system and, based on the experiments carried out, recommendations for the activation of the second server are defined.
