The maths don't add up...
Dear Sir,
could you kindly get in touch with Samsung and ask them how it is possible that a 30 minute outage caused 11% of their monthly output in ruins?
11% of a month (in time) is roughly 3.3481 days, which is roughly 4821.30 minutes... Since it's a plant, I am assuming 24x7 operations...
Maybe they operate 8 hours a (a third - still leaves 1607.10 minutes in 11%) and only during the week (so operating on 5/7 - still leaves 1147.9286 minutes).
Even with 8-hour week-day-only shifts, 30 minutes is only 2.6134% of the 11% that Samsung claim is now in ruin. What is Samsung doing with its NAND Flash plant?
Reasoning it the other way around:
11% of production in ruins whilst off-line for 30 minutes means that 100% of production can be created in roughly 270 minutes (9 x 11 = 100; 9 x 30 = 270). 270 minutes is slightly more than half a day (8 hour working day). There's, on average, still more than 29 days left in the month after that half a day has been taken away from an average month 30.odd days...
It does not make any sense whatsoever...
Regards,
Guus
