Abstract: The purpose of an operating system is to provide an interface in which a program can execute in a convenient and efficient manner. While designing an operating system, a programmer must consider which scheduling algorithm will perform best for the system. There is no universal “best ” scheduling algorithm, and many operating systems are using extended or combinations of the scheduling algorithms. The efficiency of scheduling depends on optimal time quantum and proper distribution of system resources. So, we have proposed a new algorithm known as advanced mix job with dynamic quantum round robin (AMDRR) scheduling algorithms. We have experimentally shown that the efficiency of AMDRR is better than conventional RR(round robin) and DQRRR (dynamic quantum readjusted round robin) by reducing its context switching, average turnaround time and average waiting time
