A small automated system in a bakery produces loaves of bread. The doughmaking machine ejects a portion of dough every UNIF(0.5, 1.0) minute. This portion of dough enters a hopper to wait for space in the oven. The portions will be ejected from the hopper in groups of four and placed on the oven-load area to wait for space on the oven conveyor. There is room for only one group of portions at the oven-load area. The oven conveyor has ten buckets, each 1 foot long, and moves at 0.34 feet per minute.

(a) Develop your model using the Hold (Scan for Condition), Signal, and Hold (Wait for Signal) modules for your logic to control the group of portions. Run it for 3,000 minutes and observe statistics on the number of portions in the hopper, oven utilization, and the loaf output per hour.

(b) Modify your model from part

(a) by replacing the Hold (Scan for Condition) module with logic developed based on the Decide module.
