There dynamic time-quantum that regulate the burst time in

There are many techniques works done on Scheduling algorithm that worked on time of arrival and latency. Working on Scheduling improved with the passage of time. The author {Chhugani, 2017 #1} worked on dynamic time
quantum that calculates parameter of scheduling. The result shows that the way to increase the time
quantum for few processor because of threshold
value. The author {Rajput, 2012 #2} proposed an algorithmic program that supported priority primarily based algorithmic program and compares with normal round robin. The fuzzy technique supported pre priority and
execution time and compare with the various algorithmic program and shows higher result in
{Kumari, 2017 #3..

FJFDRR targeted on round robin with dynamic time slice and compare
with the various technique and shows the higher result in {Mohanty, 2012 # 4}.{Mohanty, 2012
#5} planned a replacement technique that calculates fit factor and dynamic time slice. fit factor  supported the mixture of FCFS, SJF, and priority algorithmic program and show the higher result as compared to the other scheduling algorithmic program. SJFDRR works on time quantum and improves the potency of round robin. In this paper, there are user and system priority. User priority has necessary than system priority and
reduced the context switching in {Gupta, 2016 #6}. . Self Adjustment round Robin (SARR) solves the matter of dynamic time-quantum
that regulate the burst time in line with the running algorithm. The planned algorithmic program also can be enforced on an large processor and also the software system itself can determine the optimum time quantum in {Matarneh,
2009 #7}. {Mohanty, 2011 #8} represents the algorithmic program that is called priority-based dynamic round robin that calculates intelligent
time slice for individual method and changes the time
slice before every execution. FPRRDQ shows the higher result as compared to
other alternative programs that is based on the user priority and quantum time t when each execution in line with priority and burst time
in {Srivastav, 2012 #9}.. Optimum service time conception for round-robin algorithmic program works on associate optimum priority of every method associated placed in an order of execution in line with calculated priority in
{Saxena, 2012 #10}. .
FCFS work on the idea of the FIFO. Each process executed according to its number. FCFS performs well for smaller values. It shows poor
waiting time, turnaround for giant computation.SJF worked
on the idea of shortest CPU burst length. within which short method enter in execution queue
and execute first. SJF perform best for long processes as
compared to FCFS. It’s potential that long Process waits within the prepared queue for brief method that complete its task however typically it behaves like
starvation. RR worked in time quantum. RR worked sensible for short process and provides the results of minimum average time,
minimum turnaround and minimum throughout. In real time system, the overhead invokes when every context switch because of context switch exaggerated for short time quantum. Just in case of long-time quantum, method executes inside one time slice and performs higher result. Priority-based algorithmic program worked on low and high priority. Typically it becomes suffer a serious downside known as starvation as a result of low priority failed to execute because of high priority. 
To avoid the matter of overhead and starvation, a replacement technique  should be introduced to resolve this downside and average waiting
time, average turnaround and average response time should be increased.
