In 2005, the plant’s overtime costs were high and the trucks spent too much time waiting to unload the process fruit onto the dumpers. The reason was that the plant could process less fruit than it received resulting in holding bins that were always full leading to long waiting time for the trucks. Also, because of the increase in water harvesting of the cranberries, new schedules for operations had to be drawn up. Another issue was the grade selection of the berries. Half the grade 3 berries were actually grade 2B resulting in revenue and time loss. Daily maintenance activities prevented round the clock operations within the facility and lead to a production loss of 2 hours/day.
2) Draw a process flow diagram of the cranberry process beginning with receiving and ending with the Bailey Mills (i.e., ignore Sorting and Shipping at the end of the process). 3) Compute the capacity in barrels per hour for each step. Temporary Holding Bins for dry= (16 bins) x (250 bbls) = 4,000 bbls Bins for wet=(3 bins) x (400 bbls) = 1,200 bbls Bins for both=(8 bins) x (250 bbls) = 2,000 bbls
Total Capacity = 7,200 bbls Destoning (for dry only)
Total Capacity = (3 machines) x (1,500 bbls/hr) = 4,500 bbls/hr Dechaffing Wet= (2 machines) x (1,500 bbls/hr) = 3,000 bbls/hr Dry= (1 machines) x (1,500 bbls/hr) = 1,500 bbls/hr
Total Capacity = 3,000 bbls/hr + 1,500 bbls/hr = 4,500 bbls/hr Drying (for wet only)
Total Capacity = (3 machines) x (200 bbls/hr) = 600 bbls/hr Separator
Total Capacity = (3 machines) x (400 bbls/hr) = 1,200 bbls/hr
4) Consider a peak harvest day (19,000 barrels of berries unloaded with 70% of them wet harvested). Assume that trucks arrive uniformly over a period of 12 hours. Identify the bottleneck for the process.
Max. number of barrels unloaded during peak harvest = 19,000
Wet harvest = 70% x 19,000 = 13,300 bbls

1889 Words | 8 PagesAlthough a fifth Kiwanee dumper was updated last year with the hope of resolving the problem, it was unable to fix them and the overtime costs of the process are still very high. 2. There is a long waiting time for trucks and drivers in queuing to unload process fruit into the receiving plant. Seriously, when the holding bins were full, the waiting time could be up to several hours. This has upset the growers since the wages of a truck and drives are up to $100 per hour.

270 Words | 2 PagesWet berries are 70% of all berries. Holding bins 17-24 are dedicated to wet berries. Capacity of the dumpers is 3,000 bbl / hr (it takes on average 7.5 minutes to dump a truck, a truck holds on average 75 bbl so, from Little's Law, each of the five dumpers will take 600 bbl/hr). Drivers are paid $18/hr. Rates for other employees are given in the case.

Next, divide by the density (you’ll have a label of mole/g at this point). Then multiply this by the molar mass of NaClO which has a label of g/mol so all labels cancel.

817 Words | 4 PagesThe 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.

481 Words | 2 PagesUnfortunately, Brisbane residents are unable to conserve water without restrictions, which is why the restrictions system is utilized by local government. Brisbane residents have lived with level 6 water restrictions for the past 2 years and as they have been so limited there will undoubtedly be a self indulgent splurge by almost ever house hold. The dams won’t be able to handle the rush and it will only result in short term gain for long term loss. On level 6 water restrictions, the parameters for water use are 140 liters per person per day. At 40 per cent of the reserves, water restrictions will be reduced to level 3 which is 170 liters per person per day.
