1.) The developers of the JIT concepts utilized a simple card system called kanban Oishikawa coding time fences 2.) MAD is the sum of absolute deviationsumber of observations the sum of absolute deviations * the number of observations the number of observations/the sum of absolute deviations period average demand * deseasonalized demand 3.) The two-bin system is a simple way of keeping control of items because they are of low value. B 2 D c 4.) Demand is 200 units a week, the lead time is 3 weeks, and safety stock is 300 units. Calculate the order point. + 300 600 900 none of the listed is correct|
