If the waiting time cost per hour for a FAST truck is $100 and the waiting time cost per hour for a non-FAST truck is $40. Build the following ARENA models to help you decide which option is cost optimal.
a. One secondary inspection agent is removed and an additional booth is added at the primary inspection lane which could be used by either truck.
b. One secondary inspection agent is removed and an additional booth is added at the primary inspection lane which could be used only by FAST trucks.
c. FAST trucks have priority over Non-FAST trucks at secondary inspection. In other words, even if a Non-FAST truck that came in to the secondary inspection parking lot ahead of the FAST truck is awaiting inspection, the FAST truck will be inspected before the Non-FAST truck. The priority policy is non-preemptive priority.
d. Original model
What is the total waiting cost per hour in each of the above 4 cases. Which is cost optimal? If you encounter the situation that 150 entities are exceeded in any of the above cases, discard that case from your comparisons. Support your answers in parts a. to d. by printing out the appropriate ARENA reports.
