A call center operates with 130 customer service representatives in an 8-hour period.
The company receives 8,000 calls per day, and the average call takes 7 minutes. What
is the utilization of the call center?
0.9
0.91
0.97
1.03 - answer0.9
Available time = 8 x 130 x 60 = 62,400 minutes; call time is 56,000 minutes; utilization =
56,,400 = 90%
Which of the following information is most critical when using capacity planning to
validate the material plan?
Theoretical capacity
Standard hours/part
Key work centers
Demonstrated capacity - answerDemonstrated capacity
Demonstrated capacity identifies what the work center has been able to achieve in the
past.
A company has few products but highly variable order quantities, and it uses forward
scheduling. Why is it beneficial to use standard run hours as a basis for calculating
completion dates?
It automatically balances the load across operations.
It helps to prioritize orders in key work centers.
It provides a more realistic completion date than using fixed lead times.
It provides start times knowing queue and setup times. - answerIt provides a more
realistic completion date than using fixed lead times.
The ability of manufacturing to respond quickly to external or internal changes is:
configurability.
adaptability.
agility.
flexibility. - answerflexibility.
Theoretical capacity is most closely approached by:
a synchronous assembly line consisting of automated and manual operations.
automated machining centers dedicated to a product family.
a heat-treating furnace that operates 7/24/365.
, a lean manufacturing line using kanbans. - answera heat-treating furnace that operates
7/24/365.
A continuously operating machine would be close to theoretical capacity.
Based on the information provided below, what is the rated capacity of the work center?

Available hours x utilization x efficiency = [(20 workers x 8 hours x 1 shift x 5.5 days) -
0.8 hours] x (7.1 hours/7.2 hours) x (7.0 hours/7.1 hours) = (880 hours - 0.8 hours) x
0.9861 x 0.9859 = 855 hours (rounded).
A textile plant spins fiber into yarn, weaves the yarn into a line of standard fabrics, and
dyes these fabrics to custom color specifications. Dyeing is done in a light-to-dark
sequence to reduce high changeover costs. While spinning and dyeing capacity is
adequate during the peak season, the capacity of the plant's weaving operations is well
below the required level. If product design and price are the primary competitive factors,
which of the following actions would effectively resolve the problem?
Changing dyeing schedules to use subcontractors for dyeing during the peak season
Changing weaving and dyeing schedules to accommodate the needs of key customers
Building inventory of feed yarn just before the peak season begins
Building inventory of undyed fabric just before the peak season begins - answerBuilding

Using suppliers to perform subcontracted operations requires that the services to be
performed are:
