A number of people and execution time


Now we consider three tasks A, B and C and these tasks have no particular order.

The required time of each task is T (minutes) and the required number of people is 2.

Now, the simulator can assign 6 people, the task A, B and C can be done in parallel, so total time to complete the task A, B and C is T minutes.

 

parallel

 

But, the simulator can assign only 2 people at the moment, the task A, B and C should be done in sequence, so total tome to complete is 3T minutes.

 

serial

 

So, total time to complete tasks depends on how many people can be assigned in that moment.
