A Review on using MLQ-Fuzzy Logic in CPU Scheduling

In this paper we propose Scheduling which is a decision making process which deals with the allocation of resources to tasks over given time periods. Scheduling is done by scheduler and dispatcher. A scheduler is a person or machine that organizes or maintains schedules. A dispatcher is a module which gives control of CPU to the process selected by the scheduler. In this paper we propose using the scientific method to develop a deeper understanding of CPU schedulers; we use this approach to explain and understand the sometimes erratic behavior of CPU schedulers. This paper present a new set of fuzzy rules. It demonstrates that scheduling done with new priority improves average waiting time and average turnaround time. We have considered the multi level queuing scheduling algorithm for optimization by fuzzy logic. This scheduling algorithm has two queues, one is at highest priority and execute tasks in round robin fashion while other is batch queue and executes in first in first out (FIFO) sequence.
