Consider a peak harvest day having 18,000 barrels of berries unloaded, with 70% being wet harvested.

Assume that trucks arrive uniformly over a period of 12 hours. 

i. Identify the primary and secondary bottlenecks in the process. FYI, the primary and secondary

bottlenecks have, respectively, the highest and second-highest implied utilization; primary

bottleneck restricts process flow rate the most.

ii. When would processing be completed on a peak day? Explain your reasoning.

iii. Draw a plot (or provide a data table) of total wet berry inventory over time in the system for a peak

day. Note: It may suffice to use a time unit of an hour as most segments of the graphs are linear.

iv. When would the last truck unload and how long would it have waited?

v. Estimate the average cost of waiting trucks on a peak day.
