- Q1
In an A-B-C system, the typical percentage of the number of items in inventory for A items is about:
50
50
30
10
30s - Q2
In the A-B-C classification system, items which account for fifteen percent of the total dollar-volume fora majority of the inventory items would be classified as:
A items
B items
C items
A items plus B items
30s - Q3
It is the process of shaping a material by forcing it, under pressure, to flow through a die.
Compression Molding
Extrusion
Injection Molding
Transfer Molding
30s - Q4
It is the process of forming articles by placing raw materials (pellets, granules, etc.) into one end of a heated cylinder, heating the material in the heating chamber, and pushing it out the other end of the cylinder through a nozzle into a closed mold, where the molding material hardens to the configuration of the mold cavity.
Extrusion
Transfer Molding
Injection Molding
Compression Molding
30s - Q5
In the A-B-C classification system, items which account for sixty percent of the total dollar-volume forfew inventory items would be classified as:
A items plus B items
C items
A items
B items
30s - Q6
The purpose of “cycle counting” is to:
count bicycles and motorcycles in inventory
reduce theft
reduce discrepancies between inventory records and actual
count all the items in inventory
30s - Q7
The EOQ model is most relevant for which one of the following?
ordering perishable items
determining fixed order quantities
determination of safety stock
ordering items with dependent demand
30s - Q8
Which is not a true assumption in the EOQ model …
Lead time doesn’t vary
Usage rate is constant
No more than 3 items are involved
Production rate is constant
30s - Q9
Gourmet Pretzels bakes soft pretzels on an assembly line. It currently bakes 800 pretzels each 8-hourshift. If the production is increased to 1,200 pretzels each shift, the productivity increases by:
50%
33%
67%
25%
30s - Q10
To eliminate bottlenecks, if any, a company should:
All of the choices
restudy the existing work method to see if task times can still be reduce
assign more than 1 worker to the bottleneck station(s)
assign 1 worker to work on 2 or more stations so long as their combined task time is less than the cycle time
30s - Q11
Averaging techniques are useful for:
smoothing out fluctuations in time series
eliminating historical data
distinguishing between random and non-random variations
providing accuracy in forecast
30s - Q12
Putting forecast errors into perspective is best done using
Exponential smoothing
MAPE
MAD
Linear decision rules
30s - Q13
Moving average forecasting techniques do the following:
immediately reflect changing patterns in the data
lead changes in the data
operate independently of recent data
smooth variations in the data
30s - Q14
In order to increase the responsiveness of a forecast made using the moving average technique, the number of data points in the average should be:
decreased
multiplied by a larger alpha
increased
multiplied by a smaller alpha
30s - Q15
Simple exponential smoothing is being used to forecast demand. The previous forecast of 66 turned outto be four units less than actual demand. The next forecast is 66.6, implying a smoothing constant, alpha,equal to:
.10
.01
.15
.20
