1. Berlin Industries uses a kanban system to manage production of the R-15 subassembly. They have an hourly demand for 250 units and use containers that can hold 50 parts each. It takes 90 minutes to fill and move a container of parts to the right place on the R-15 line that is currently rated at a 20% safety factor.
Calculate the maximum system inventory for this part.
450 units
400 units
2,500 units
5,000 units
75 units
2. 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.
If the required safety stock was changed to zero and 3 containers were being used in the system, calculate the maximum inventory.
4,100 units
400 units
150 units
5,000 units
1,300 units
3. An integrated electronic-chip manufacturer has a demand for a specific component of 800 parts per 8-hour day. The manufacturer wants to design a lean system using containers. The containers the manufacturer used for this component held 20 parts. It takes about 4 hours to round-trip a container from one work center to the next and back again. The manufacturer also wants to hold 10% of safety stock of this part in its system.
If the required safety stock was changed to zero, how many containers should the lean system be using, all else being constant?
