Case Report: National Cranberry Cooperative 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. Finding Numbers for Process Flow Diagram Capacities Used in Diagrams Dumpers: (60min/7.5min)*75bbl=600bbl/dumper, 600*5=3000bbl/hr Storage: Bins 1-16 hold 250bbl each=16*250=4000bbl/hr Bins 17-24 hold 250 bbl each and bins 25-27 hold 400 bbl each=(8*250)+(3*400)=3200bbl/hr 2 Destoners and 2 Dechaffers are currently for wet and 1 Destoner and 1 Dechaffer for dry So 1500bbl*2=3000bbl/hr 1500bbl*1=1500bbl/hr Calculations are for both destoners and dechaffers Dryers: 200bbl each, 200bbl*3=600bbl/hr Seperators: 400bbl each, 400bbl*3=1200bbl/hr Utilization formulas -Implied Utilization=Demand/CapacityUsed in diagram above (implied) -Actual Utilization=Throughput Rate/CapacityUsed in diagram below (actual) Throughput Rate for wet-600bbls/hr Throughput Rate for dry-375bbls/hr Total Throughput Rate-975bbls/hr 2. The maximum current throughput rate of RP1is 975bbl. Because the maximum throughput rate for wet berries is 600bbl/hr due to the bottleneck/dryers. 375 bbl/hr is the throughput rate for the dry berries. So, 600bbl/hr for wet plus 375bbl/hr for the dry equals a total throughput rate of 975bbl/hr 3. Buildup begins 7 am at a rate of 1125-600=525bbl/hr until 7pm when buildup is reduced at 600bbl/hr Trucks begin to wait at 3200/525=6.1 hrs after 7 am or 1:05 pm Peak is at 7 pm with 6300bbl/hr so (6300-3200)/600=5.16 hrs or 12:09 am there are 0 trucks waiting Total truck wait time is a little over 11 hours 6300/600=10.5 so the factory finishes 10.5 hrs after 7 pm or 5:30 am the next morning Factory run time is 20.5 hours 4. The potential investments NCC is considering buying a new
