Hi, I am a grad student workin on SMT placement optimization and i am exploring the possibility of utilizing unused slots and assigning multiple feeder slots for a component type on a chip shooting machine. so far my optimization model has shown very good results in terms of reducing the downtime due to replenishments (upto 45%) through effective exhaust synchronization. But to make it more robust against variation in the reel sizes I need some information regarding whether the number of components in the reels are very accurate or does it have any variation in it. In otherwords, if the manufacturer claims to have 10000 components in a reel, does the reel contains exactly 10000 components or does it have any variation. any help on this isssue will expedite my research and effective tuning of the optimization model. thanks -govi
