1. Copenhagen Industries uses a kanban system to manage production of their subassembly. In a 10-hour day, they use 1,500 units and use containers that can hold 50 units each. It takes 45 minutes to fill and move a container of parts to the right place on the subassembly line that is currently rated at a 15% safety factor.

2. The Frankenmuth Fasteners Co. was implementing lean throughout their shop floor and needed to determine the number of containers at several of their work centers. In one such work center, the demand was 200 parts per hour, and the containers they used for this part held 50 parts. It normally takes 6 hours for a full container to make a circuit through the work cell and back to its input side, and they desired to carry 12% safety stock in the system.
If the required round-trip time from the original data was changed to 5 hours, how many containers should the lean system be using, all else being constant?
