create a total time = 0 + 3 = 3 (running total 1). In that time‚ if you look at the arrival times‚ in the arrival time column above‚ P2 arrives at time = 1‚ but P3 also arrives at time = 3‚ and by this time P1 has finished executing‚ so you look at both P2 and P3‚ and you start executing the process with the shorter burst time‚ which is P2 with a time = 6. So P2 will run until it has finished its execution‚ its burst time = 6. You add this burst time = 6 onto the total which was calculated above when
