Fuzzy based multilevel feedback queue scheduler

Abstract

In multilevel feedback queue scheduling algorithm the major concern is to improve the turnaround time by keeping the system responsive to the user. Presence of vagueness in a system can further affect these performance metrics. With this intent, we attempt to propose a fuzzy based multilevel feedback queue scheduler which deals with the vagueness of parameters associated with tasks as well as to improve the performance of system by reducing the waiting time, response time, turnaround time and normalized turnaround time. Performance analysis shows that our methodology performs better than the multilevel feedback scheduling approach.
