accurate answers
A characteristic that can be used to guide the design of service systems:
Ans🗸🗸🗸 Services cannot be inventoried
A mathematical expression that relates inventory, throughput, and flow
time: Ans🗸🗸🗸 Little's Law
A physical inventory taking technique in which inventory is counted on
a frequent basis rather than once or twice a year: Ans🗸🗸🗸 Cycle
Counting
A probability distribution often associated with interarrival times:
Ans🗸🗸🗸 Exponential distribution
A process structure designed to make discrete parts. Parts are moved
through a set of specially designed workstations at a controlled rate:
Ans🗸🗸🗸 Assembly Line
A production environment where pre-assembled components,
subassemblies, and modules are put together in response to a specific
customer order: Ans🗸🗸🗸 Assemble-to-order
A production environment where the customer is served on-demand
from finished goods inventory. Ans🗸🗸🗸 Make-to-stock
,A production environment where the product is built directly from raw
materials and components in response to a specific customer order:
Ans🗸🗸🗸 Make-to-order
According to Little's Law, which of the following can be used to
estimate work-in-process inventory: Ans🗸🗸🗸 Throughput times flow
time
After determining the significance of the model (using the ANOVA
table), the next step is: Ans🗸🗸🗸 Evaluate R-square
An area where simple items that are similar in processing requirements
are produced: Ans🗸🗸🗸 Manufacturing cell
An inventory control model that specifies inventory is ordered at the end
of a predetermined time period: Ans🗸🗸🗸 Fixed-Time Period Model
An inventory control model where the amount requisitioned is fixed and
the actual ordering is triggered by the inventory dropping to a specified
level: Ans🗸🗸🗸 Fixed Order Quantity
An often automated process that converts raw materials into a finished
product in one contiguous process: Ans🗸🗸🗸 Continuous process
As you make the value of alpha smaller, you can avoid one kind of
problem. However, another kind of problem will become more likely.
, Pick the right pair of problems, and in the right sequence (which gets
better, which gets worse): Ans🗸🗸🗸 False positive; false negative
Can you add, subtract, multiply and divide standard deviations?
Ans🗸🗸🗸 No
Consists of three major components: (1) the source population and the
way customers arrive at the system, (2) the serving systems, and (3) how
customers exit the system: Ans🗸🗸🗸 Queuing system
From the slides, regarding Poka-Yokes, which one is not one of the three
T's: tangible features, treatment, time or task: Ans🗸🗸🗸 Time
Generally speaking, the "skew" in the distribution is usually thought to
be because of the presence of: Ans🗸🗸🗸 Outliers
Here the firm works with the customer to design the product, which is
then made from purchased materials, parts and components: Ans🗸🗸🗸
Engineer-to-order
How much of a normal distribution is between values located at one
standard deviation above and one standard deviation below the mean?
Ans🗸🗸🗸 68%
