Unformatted text preview: ewise, downstream functional testing processes were also assumed to have excess capacity. The MTSA machine had a capacity that varied depending on the mix of cards being tested:
particular cards could only be tested in particular slots in the machine and there were only a fixed
number of each type of slot. There were 49 different types of cards scheduled to be produced, and
equipment documentation indicated that the average capacity for a particular type of card in the
MTSA machine was 7.5 cards, with a standard deviation of 3.8. Because it is likely that multiple
card types in the same run will not need the same slot, actual capacity of the equipment is generally
somewhat higher than the average, but for conservative purposes, we say that the capacity of the
equipment for a given run is a random variable, C, where
C ~ N(7.5, 3.8). (5.6) Each run was programmed to take 19 hours to complete, although in some cases the equipment
failed to achieve the temperature profile within the control limits and had to be manually restarted. Based...
