Several scheduling policies like FCFS, SJF, Priority, RR, SRTN etc. have been studied so far. The scheduling decision from these policies are generally based on crisp parameters. However, practically it has been observed that in many real world situations these parameters are vague or imprecise in nature. Due to the vagueness behavior, the scheduler uses fuzzy logic in scheduling algorithms that incorporates fuzziness of CPU burst time. A comparative study has been made regarding performance measures based on bubble sort of various CPU scheduling policies. The study helps the designer in selecting the best scheduling policy at hight Abstraction level.
