1) Introduction
Throughout National Cranberry Cooperative (NCC) case, we know that there are some problems in Receiving Plant No.1 (RP1). At the intro part of the NCC case, vice president of operation at the NCC, Hugo Schaeffer said “……our overtime costs were still out of control this fall, and the growers are still upset that their trucks and drivers had to spend so much time waiting to unload process fruit into the receiving plant……” From his comment, we know that problems of overtime costs and excessive waiting time have caused. Followings are the major cause and recommended solutions we came up with to the problems.
2) Capacity & Problem Analysis
I. Capacity Analysis
RP1 was highly mechanized. The process could be classified into several operations : receiving and testing, dumping, temporary holding, destoning, dechaffing, drying, separation, and bulking and bagging. We found major bottleneck on the dryers through NCC flowchart.
First, Bulk trucks carrying process berries arrived at RP1, loading 20~400 bbls. These trucks arrived randomly and average truck delivery was 75 bbls. Truck usually took from 10 minutes to back a truck onto a dumper( 6 trucks/ hour) and they moved to five dumpers. So total dumps capacity is 75 (bbls/truck) X 6 (truck/hour) X 5 dumps = 2250
Second, temporary holding bins capacity :
1)Only dry berries bins (bins 1~16): 16 bins X 250bbls = 4000bbls
2)Wet of dry berries bins (bins 17~24): 8 bins X 250bbls = 2000bbls
3)Only wet berries (bins 25~27) : 3 bins X 400bbls = 1200bbls
