Abstract:

Polling control system is widely used in production and life including time-sharing computer systems, industrial control, communications, and computer networks. The article proposes a new polling control system based on Busy/Idle queues, which sorts normal polling queues into Busy Queues (BQ) and Idle Queues (IQ) according to if there are customers in the queue. Then, BQ is served by a Gated access policy and IQ keeps a sleeping state until it is woken up by arriving customers. Moreover, parallel scheduling is used to save switch-over time. We build a system model using the embedded Markov chain, probability mother function, the throughput, cycle time, mean queue length and mean waiting time of significant system characteristics. Theoretical calculated values are approximately equal to the simulated values, indicating that the new system is correct and achieves a better performance than the traditional polling scheme.
