Question 1: (10 points) Analyze NCC’s Process: Capacity and implied utilization
A. Labelled diagram. (use & edit diagram supplied below)
B. Calculation detail.
a. Dumpers
i. Capacity= 3,000 bbl/hr (given in briefing)
ii. Implied utilization= demand/capacity
1. Demand= 17,280/12= 1440
iii. 1440/3000= 48%
b. Bins max contents
i. Dry
1. Bins 1-16, each holds 250  250*16 = 4,000 bbl
ii. Wet
1. Bins 17-27, 17-24 hold 250, 25-27 hold 500 = 8*250 + 3*400 = 3,200
bbl
c. Destoning (dry only)
i. Capacity
1. 1,500 per destoning unit (3 units).  1,500 * 3 = 4,500 bbl/hr
ii. Implied utilization
1. Demand / capacity = 25% * 1,440 = 360/ 4,500 = 8%
d. Dechaffing
i. Dry
1. Capacity= 1,500 per unit, 1 unit  1,500 bbl/hr
2. Utilization= 360/1500= 24%
ii. Wet
1. Capacity= 1,500 per dechaffing unit, 2 units  3000 bbl/hr
2. Utilization= 1080/3000 = 36%
e. Drying (wet only)
i. Capacity= 200 bbl/hr per unit, 3 units = 600 bbl/hr
ii. Utilization = 1,080/600 = 180%
f. Separating
i. Capacity
1. Used average capacity of 400 bbl/hr per line, 3 lines = 1200 bbl/hr
ii. Utilization
1. 1440/1200= 120%
C. Maximum hourly throughput rate, & limiting resource area
a. Maximum hourly throughput rate= bottleneck of wet process + bottleneck of dry=
600 + 360 = 960 bbl/hr
b. Limiting resource= drying, highest implied utilization, lowest capacity
Question 2 (15 points) Analyze expensive issues NCC faces in financial terms using operations tools.

A. inventory buildup diagram
o
B. total truck waiting time in truck-hours.
o Truck waiting time = (16.266-6.666)
 9.6 hours
C. costs of overtime operations
o assuming seasonal workers, paid $8 per hour + 1.5x for overtime = $12/hr
o case states that 8-9 workers usually work overtime, assume 8.5 workers
o $12/hr * 8.5 workers on average * 5.6 hours
 $571.20 overtime operations cost per day
 105 days
 $59,976 per season

with 5 dumpers
B. One new dryer
C. Two new dryers
