Assume that a plant operates 2,000 hours per year and the demand rate for parts is 100,000 units per year. The circulation time for each kanban container is 24 hours.
How many kanban containers are needed for a container size of 100 parts?
What would be the effect of reducing the container size to 60 parts
What is the takt time for this process?
What takt time is needed for 80,000 units per year?
Usage at a work center is 300 parts per day, and a standard container holds 25 parts. It takesan average of .12 day for a container to complete a circuit from the time a kanban card isreceived until the container is returned empty. Compute the number of kanban cards (containers) needed if X = .20.
A supplier of instrument gauge clusters uses a kanban system to control material flow. The gauge cluster housings are transported five at a time. A fabrication center produces approximately 10 gauges per hour. It takes approximately two hours for the housing to be replenished. Due to variations in processing times, management has decided to keep 20 percent of the needed inventory as safety stock. How many kanban card sets are needed?
