Empty bags arrive at a bagging system according to an exponential distribution of 3 minutes. The bags are then filed by filling machines, there are 2, and its takes them between 4.2 and 5.8 minutes to fill a bag. After the bags are filled they go to a sealing machine, processing time is TRIA (3, 4, 5) minutes. Assume there are no constraints on the sealing machine. As soon as the bags are sealed they are weighed and marked. This process is done by one of four operators and takes between 10 and 14 minutes to complete. Create a simulation model and run it for 8 hours. Determine the average time in process and queue lengths
