Parallel Service with Vacations
We study a system with unlimited service potential where all service requests are served in parallel. The entire system itself becomes unavailable for a random period of time at the first instance that the system becomes idle. A queue builds up while the system is unavailable, and then all waiting customers enter the system simultaneously-each to its own processor-when the system becomes availa...
متن کاملPeriodic scheduling with obligatory vacations

Each job is associated with a profit that is gained each time the job is completed, and the goal is to maximize the average profit per time unit. Once the processing of a job is completed, it goes on vacation and returns to the system, ready to be processed again, only after its vacation is over. This problem has many...

This is, for example, the case in remote systems where customers may decid...
متن کاملQueueing Models with Vacations and Their Applications
vi Preface A variety of queueing models have been proposed and analyzed to evaluate the pelformance of systems such as computer, communication and manufacturing systems. Among them, queueing systems with vacations have been extensively studied in the last two decades since those have a lot of applications in those real systems. For example, in most computer systems, a processor is shared among ...
