Solutions
A certain product costs $200 to order. The cost per unit is $25
and the cost to carry one unit in inventory for 1 year is 20% of
the value of the product. Monthly demand is 1,000 units. The
company operates 5 days a week, 4 weeks per month.
Assume the company manufactures the unit instead of
purchasing it, and so the replenishment is not immediate, but
rather gradual over time. If the production rate is 750 units per
day, what is the optimal order quantity? Correct Answer 1014

A process, when in control, produces an output that has these
statistics: X-doublebar = 253; R-bar = 48; these statistics were
calculated from 8 samples, each containing 15 observations.
Using three standard deviation control limits, determine the LCL
for the R chart and the UCL for the X-bar chart. LCL for Range
Chart UCL for X-bar Chart Correct Answer 16.8 263.6
A pure level strategy for aggregate production planning:
Correct Answer Maintains a stable workforce working at a
constant output rate.
