A Company produces mechanical probe to update OWSVS (Offensive-Warfare-Support- Vehicle- Systems). For the process of making a mechanical probe, 10 process steps are needed. It is calculated that the scrap rate and rework rate are 12% and 9%, respectively. The average setup time, average machining (operational) time and the average non- operational time can be expressed as: 2.4 hours, 9.6 minutes, and 9.6 hours, respectively. a) With a batch size of 520 mechanical probes, what must be Manufacturing Lead Time (MLT) in hours? b) With 8 hours per shift and two shifts per day, if the plant works 5 days a week, what is the MLT in weeks? c) If the availability factor can be expressed as 81%, then what must be the value of MLT?

Question
A Company produces mechanical probe to
update OWSVS (Offensive-Warfare-Support-
Vehicle- Systems). For the process of making a
mechanical probe, 10 process steps are
needed. It is calculated that the scrap rate
and rework rate are 12% and 9%, respectively.
The average setup time, average machining
(operational) time and the average non-
operational time can be expressed as: 2.4
hours, 9.6 minutes, and 9.6 hours,
respectively.
a) With a batch size of 520 mechanical
probes, what must be Manufacturing Lead
Time (MLT) in hours?
b) With 8 hours per shift and two shifts per
day, if the plant works 5 days a week, what is
the MLT in weeks?
c) If the availability factor can be expressed as
81%, then what must be the value of MLT? (in
hours and weeks)
