1. Mark the capacity and utilization of each resource in the process flow diagram at the end of this document. Briefly describe how you calculate the capacity and utilization here. [20 points]

On average, 18000 barrels arrive over the 12hr span that the business is open. This means approximately 1500 barrels of berries are input into the process per hour (18000barrels/12hrs). The capacity of the Kiwanee dumpers was given as 3000 b/hr., and I was able to calculate the implied utilization by dividing the berry input rate by the capacity(1500bbl/hr divided by 3000bbl/hr). To calculate the actual utilization of the dumpers, you must first determine the flow rate of the system. Only 25% of the berries are dry and 75% are wet. This sums to 375 dry berries per hour (1500 input/hr x.25) and 1125 wet berries per hour (1500 input x .75). The dry berries have 16 bins that hold 250 barrels a piece, adding up to a total of 4000 berries that can be stored. The wet berries have 8 bins that hold 250 barrels and 3 bins that hold 400 barrels, adding up to 3200 barrels total for storage. The capacity of the DeStoners was given as 1500bbl/hr. The implied utilization would be the input rate (1500bbl/hr) divided by the capacity (1500 bbl/hr). Since the bottleneck...
