4 Principles of Bottleneck Management Correct Answer 1.
release work orders to the system at the pace set by the
bottleneck's capacity
2. lost time at the bottleneck represents lost capacity for the
whole system
3. increasing the capacity of a nonbottleneck is a mirage
4. increasing the capacity of the bottleneck increases capacity
for the whole system
A plant is designed to manufacture 2700 widgets per day.
However, the plant's utilization is only 73%, while its effective
capacity is 2160 widgets per day. The plant's efficiency is
Correct Answer Efficiency Rate= (2700*.73)/2160= .9125->
91.25%
A production line at V. J. Sugumaran's machine shop has three
stations. The first station can process a unit in 6 minutes. The
second station has two identical machines, each of which can
process a unit in 16 minutes (each unit only needs to be
processed on one of the two machines). The third station can
process a unit in 9 minutes.
which station is the bottleneck station and what is the bottleneck
time? Correct Answer Station 3 is the bottleneck, with a
bottleneck time of 9 minutes per unit
Station1 Bottleneck= 60/6=10 units/hr
Station2 bottleneck= (60*2)/16=7.5units/hr
Station3 bottleneck= 60/9= 6.67 units
, A work cell at Chris Ellis Commercial Laundry has a
workstation with two machines, and each unit produced at the
station needs to be processed by both of the machines. (The
same unit cannot be worked on by both machines
simultaneously.) Each machine has a production capacity of 12
units per hour. Find throughput Time Correct Answer
Throughput Time= (60*2)/12= 10 Minutes per unit
According to The Goal, what is the goal of a for profit
organization?
- Make money.
- Make cost-effective purchases.
- Produce quality products.
- Stay on the leading edge of technology.
- Increase efficiencies. Correct Answer Make Money
According to the Theory of Constraints, the four operational
measures of capacity include all of the following EXCEPT:
- throughput.
- utilization.
- delivery lead times.
- inventory Correct Answer Delivery Lead Times
Bottleneck Correct Answer An operation that is the limiting
factor or constraint. refers to the literal neck of a bottle that
constraints flow or throughput. Has the lowest effective capacity
of any operation in the system and limits output.
To determine the bottleneck in a system, identify the station
with the slowest process time, or one that takes the longest time.
