1. A lean system has the following characteristics: demand rate = 40 parts per hour; safety stock required = 10%; the container size = 8; lead time to replenish an order = 4 hours.

If the number of containers is reduced by 2 units, what would be the new required round-trip time, all else being constant?

3.64 hours

3.83 hours

4 hours

4.4 hours

Need additional information to compute the value

2. Istanbul Industries uses a kanban system to manage production of the MI6 subassembly. In an 8-hour day, they use 100 units per hour and use containers that can hold 23 units each.
