Gestalt, Inc. uses a kanban system in its automobile production facility in Germany. This facility operates 10 hours per day to produce the Jitterbug, a
replacement for the obsolete but immensely popular Jitney Beetle. Suppose that a certain part requires 60 seconds of processing at machine cell 33B and an
average container of parts averages 1.4 hours of waiting time there. Management has allowed a 12 percent buffer for unexpected occurrences. Each
container holds 27 parts, and 5 containers are authorized. How much daily demand can be satisfied with this system? (Hint: Recall that p is the average
processing time per container, not per individual part.)
The average processing time per container of parts, p, is 0.045 day. (Enter your response rounded to three decimal places.)
The average waiting time per container of parts, w, is
day. (Enter your response rounded to two decimal places.)

The action figures are purchased from Tacky Toys, Inc. and arrive in boxes of 48. Full boxes are stored on high shelves out of reach of customers. A small inventory is maintained on child-levels shelves. Depletion of the lower-shelf inventory signals the need to take down a box of action figures to replenish the inventory. A reorder card is then removed from the box and sent to Tacky Toys to authorize the replenishment of a container of action figures. The average demand rate for popular action figure, Agent 99, is 36 units per day. The total lead time (waiting plus processing) is 11 days. Jitsmart's safety stocky policy variables 0.25.

- ) Silvercrest Manufacturing Ltd. is using Kanban containers. There are two adjacent work centres, a downstream (using) and an upstream (producing) one. The using work centre has a production rate of 200 parts per day and each container holds 21 parts. It takes 0.5 days for a container to make the entire cycle from the time it leaves the upstream centre until it is returned, filled with production, and leaves again. The manager wants a risk factor of 20%arrow_forwardThe 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: N = D * (Tw + Tp) * (1+r) / c 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) At Company A, 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.
