The synchronous manufacturing approach uses backward scheduling.
Answer:
The fixed-order quantity inventory model favors less expensive items because average
inventory is lower.
Answer:
The "Z" distribution used to calculate the probability of completing a project on time is
only useful in calculating probabilities where the desired time is greater than the
expected time.
Answer:
The aggregate operations plan is developed from the master production schedule (MPS)
and the rough-cut capacity plan.
Answer:

time estimates for learning.
Answer:
The internal rate of return may be defined as the interest rate that equates the present
value of the income stream with the cost of an investment.
Answer:
In calculating the probabilities in a CPM analysis the desired time is determined by
calculating the expected time for the project as a whole.
Answer:
Fixed cost remains constant regardless of the Level of output.
Answer:
In infinite loading no consideration is given directly to whether there is sufficient
capacity at the resources required to complete the work, nor is the actual sequence of
the work as done by each resource in the work center considered.
Answer:
The "dollar days" inventory measurement is chiefly used to focus management's
attention on where inventory is located.
Answer:
Statistical process control involves testing random samples of output from a process to
determine whether the process is producing items within a pre-selected range.
Answer:
Utilization of a production process is the ratio of time that a resource is actually being
used relative to the time it is available for use.
Answer:
One of the major benefits of DFMA is that products are designed that customers will
