KEYWORDS Process scheduling, Time sharing system, Round Robin, CPU scheduler, Round Robin. According to evaluation results, the proposed scheduler minimizes some scheduling criteria (turnaround times, waiting times, and context switches in this context). A threshold is considered to determine whether the system cannot take away the CPU from the process until it finishes or the process is interrupted due to the expiration of its time slice assigned by the RR policy. The proposed scheduler improves some scheduling criteria by minimizing turnaround times, waiting times, and context switches for the running processes. The proposed scheduler is a proportional share scheduler designed explicitly for time sharing systems. If a process does not complete or get blocked. This time interval is known as a time-slice or quantum. The new proposed algorithm called Modified Round Robin based on a new method called modified time quantum the concept of this approach is to make the time context switches higher average waiting. A time quantum is generally from 10 to 100 milliseconds. A small unit of time, called a time quantum or time slice, is defined. It is similar to FCFS scheduling, but preemption is added to switch between processes. Processes are dispatched in a first-in-first-out sequence but each process is allowed to run for only a limited amount of time. Round Robin (RR) The round-robin (RR) scheduling algorithm is designed especially for timesharing systems. Their algorithm finds the time slice that gives the smallest average waiting time at. In this paper, a modified version of Round-Robin (RR) called proportional weighted round robin (PWRR) is proposed. Round robin scheduling is a preemptive version of first-come, first-served scheduling. 18 proposed a dynamic version of SRR named Changeable Time Quantum (CTQ).
