Trucks Arrive Expo 91 Interarrival Times Times Minutes Unload Area Three Docks First Truck Q43874238

Trucks arrive with EXPO(9.1) interarrival times (all times arein minutes) to an unload area that has three docks; the first truckarrives at time 0. The unload times are TRIA(25, 28, 30), TRIA(23,26, 28), and TRIA(22, 25, 27) for docks 1, 2, and 3, respectively.If there is an empty dock, the truck proceeds immediately to thatdock. Assume zero travel times to all docks. If there is more thanone empty dock, the truck places preference on the higher-numbereddock (3, 2, 1). If all the docks are busy, it chooses the dock withthe minimum number of trucks waiting. If there is a tie, it placespreference on the lowest numbered dock (1, 2, 3). Note that in “byCondition” Decide modules, the tests are done from top to bottom,and the first one resulting in a “true” sends the entity outthrough that corresponding exit point. Run your model for a singlereplication of length 20,000 minutes and collect statistics on dockutilization, number in queue, time in queue, and the time insystem.
