Question One: Process Analysis, Bottleneck, and Flow Diagram
We used barrels per hour (bbls/hr) as a common measure. Since no capacity information is provided for the receiving/testing or bulking/bagging steps, we assume that these steps are not bottlenecks. We estimated the average total input of cranberries into the system at 1,500 bbls/hr using data from Exhibit 1 and assuming that total deliveries in 1981 will be the same as 1980:
Average Wet Input = (.70)(1,500) = 1,050 bbls/hr
Average Dry Input = (.30)(1,500) = 450 bbls/hr
Our analysis (see table) indicates that the bottleneck for process fruit at Receiving Plant Number 1 (RP1) is the drying process for wet cranberries at 600 bbls/hr (see Exhibit A for flowchart).
