ABSTRACT: Disk scheduling is one of the main
responsibilities of Operating System. OS manages hard disk to provide best
access time. All major Disk scheduling algorithms incorporate seek time as the
only factor for disk scheduling. The second factor rotational delay is ignored
by the existing algorithms. This research paper considers both factors, Seek Time and Rotational Delay to schedule the
disk. Our algorithm Fuzzy Disk Scheduling (FDS) looks at the uncertainty associated with scheduling
incorporating the two factors. Keeping in view a Fuzzy inference system using
If-Then rules is designed to optimize
the overall performance of disk drives. Finally we compared the FDS with the
other scheduling algorithms.
