Questions and Answers
Suppose that the specifications for a part (in inches) are 6.00 ± 0.25. The loss right
at the range limits is $1000. What is the loss at 6.7 inch? Show answer dollars and
cents ( like $45.67).
✓ ~~~ 1000/(.25)^2= 16000
✓ 16000(6-6.7)^2= $7840.00
Given the diagram below, determine the system reliability if the individual component
reliabilities are: A = .89, B = 0.93, C = 0.92, and D = 0.94.
✓ ~~~ Parallel Product Reliabilities formula:
✓ [1-(1-.89)*(1-.93)]*[1-(1-.92)*(1-.94)]=
✓ [1-(.11*.07)]*[1-(.08*.06)]=
✓ (1-.0077)*(1-.0048)=
✓ .9923*.9952=.9875
Anna works on an assembly line where it takes her 20 minutes to produce 40 units of
a product needed to fill a container. It takes her an additional 5 minutes to transport
the container to Josh, who works at the next station. The company uses a safety
stock of 15%. The current assembly line uses 5 KanBans between Anna's and
Josh's stations. What is the demand for the product? Round to nearest unit.
✓ ~~~ Kanban Formula:
✓ 25/60= .4167
✓ 5=d(.4167)(1.15)/40
✓ 200=.4792d
✓ d=417.36
The owners of Speedy Logistics, a company that provides overnight delivery of
documents, are considering where to locate their new facility in the Midwest. They
have narrowed their search down to two locations and have decided to use factor
, rating to make their decision.They have listed the factors they consider important
and assigned a factor score to each location based on a 5-point scale 1 lowest, 5
highest). The information is shown here. What is the best location, and what is its
factor rating score? (Location 1 459)
✓ ~~~ Multiply across:
✓ Location 1-
✓ 20*3=60
✓ 30*0=0
✓ 10*5=50
✓ 40*1=40
✓ L1=150
✓ L2=380
✓ Answer: Location 2, 380
Aalogistics Co. has just signed a contract to deliver products to three locations, and
they are trying to decide where to put their new warehouse. The three delivery
locations are Chicago,Kansas City, and Memphis. Which town would be the best
place to put the warehouse?
✓ ~~~ X or Y Coordinate*Load/Total Load Amt=
82(58)+85(150)+90(95)/303=85.99
64(58)+45(150)+35(95)/303= 45
Closest Answer= Punchout X84 Y56
The following table shows the tasks required to assemble an aluminum storm door
and the length of time needed to complete each task.
What is the maximum output per hour for this line with an operator at each station?
Round to nearest unit.
