capacity of the assembling stage? What is the capacity of the (entire) process?
6 Gantt Chart
Suppose an order for 60 hamburgers is placed.
What will happen?
1:27 1:54 2:27 2:54 3:27 3:54
Cooking 10 First 20 10 Second 20
1:00 10 10 10 10 Third 20
2:00 3:00 If order continues to come, how many more hamburgers
do we produce every minute? Capacity Analysis The stove, operating 100% of the time, can push out:
20 hamburgers / 1 minute = 20 burgers per minute. The workers, operating 100% of the time, can push out:
10 hamburgers / 27 seconds = 22.2 burgers per minute. The stove is the bottleneck resource; it pushes out
the slowest amount of hamburgers per time period. Bottleneck
Bottleneck: The process with the smallest capacity.
Process Capacity: The capacity of the slowest
resource (bottleneck). Utilization Rate
Flow rate (capacity used)
Utilization rate =
Capacity Utilization rate is a measure of efficiency.
Example: At a Starbucks capacity of a cashier is 96 customers per shift.
cashier’s flow rate is 72 customers per shift. What is the capacity utilization?
72/96 = 0.75 Utilization Rate How can we interpret the number 0.75? The cashier is busy 75% of the time.
25% of the time the ca...
