Answer ALL sections. 1) The following formula is used to calculate the number of bins for a given part needed for a single Kanban loop between two cells in a production system: D(Tw +Tp) (1 + r) N Where: N = Total number of bins for a given part. D = Planned usage rate for the part (parts per day) Tw= Average waiting time for replenishment of parts (fraction of a day) Tp = Average production time for a container of parts (fraction of a day) c = Capacity of the standard container (number of parts) r=Risk factor set by management (expressed as a decimal fraction) a) At Schneider Electric Corp. the boxing station at the end of an electric switch production line has a planned daily usage rate of 150,000 switches per day and receives the switches to be boxed from the preceding station in containers which hold 3% of the day's demand. It takes 90 minutes for the preceding station to fill a bin and 9 minutes for the filled bin to be delivered to the boxing station. i) How many such bins are needed for the Kanban loop to work efficiently in this production cell, given a single 10-hour shift per day and a risk factor of 6%?
