There are different scheduling algorithms that can be used to schedule these processes based on their burst time and priority. Here are some examples:
1. Priority scheduling: In this algorithm, the processes are scheduled based on their priority. The process with the highest priority gets executed first. If two or more processes have the same priority, then the one with the shortest burst time is executed first. Using this algorithm, the order in which the processes will be executed is:
P2 (burst time: 1, priority: 1)
P5 (burst time: 5, priority: 2)
P1 (burst time: 10, priority: 3)
P3 (burst time: 2, priority: 3)
P4 (burst time: 1, priority: 4)
2. Shortest job first (SJF) scheduling: In this algorithm, the processes are scheduled based on their burst time. The process with the shortest burst time gets executed first. If two or more processes have the same burst time, then the one with the highest priority is executed first. Using this algorithm, the order in which the processes will be executed is:
P2 (burst time: 1, priority: 1)
P4 (burst time: 1, priority: 4)
P3 (burst time: 2, priority: 3)
P5 (burst time: 5, priority: 2)
P1 (burst time: 10, priority: 3)
3. Shortest job first with aging: This is a variation of the SJF algorithm where the priority of a process increases as it waits in the queue. This is done to prevent starvation of processes with high burst time. Using this algorithm, the order in which the processes will be executed is:
P2 (burst time: 1, priority: 1)
P4 (burst time: 1, priority: 2)
P3 (burst time: 2, priority: 4)
P5 (burst time: 5, priority: 5)
P1 (burst time: 10, priority: 6)
