An unloading area has three docks for incoming trucks, and operates from 9:00 to 18.00 every day. Trucks have different arrival rates depending on the clock of the day, as shown in table below. The unloading time is TRIA(10, 30, 35). Time interval Arrival Rate 09:00-12:00 EXPO(8) 12:00-17:00 EXPO(11) 17:00-18:00 The manager decided to use the first dock as the "express service dock, where only trucks with an unloading time less than or equal to 20 minutes are sent to the dock. The rest trucks are sent to the other two docks for regular service and wait the first available dock (among docks 2 and 3) a. Develop an Arena simulation model for this system, run your model for 10 days, and save your model file as Name Surname 312 FTQ2a.doe. Report the average time of trucks in the unloading area which use Dock 1 as well as the scheduled utilization of Dock 1, and fill in the attached table b. Watching the unloading operation, the manager notices that the utilization of the docks are not balanced. She therefore changes the express policy of Dock 1 a bit. A truck is directed to Dock 1 either It has an unloading time less than or equal to 20 minutes o Docks 2 and 3 are busy and Dock 1 is idle. All others trucks are then directed to the other two docks as before.

Report the average time of trucks in the unloading area which use Dock 1 as well as the henderilization in the Scheduled Utilization of Dock 1 (%) Scheduled Utilization of Dock 2 & 3 (%) Average Total Time of Trucks using Dock 1 (minutes) Answer for a) Answer for b) An unloading area has three docks for incoming trucks, and operates from 9:00 to 18.00 every day.
