Suppose you have the following information demand rate (file
Suppose you have the following information:
Demand rate (D) = 750 units per hour
Lead time (T) = 40 hours
Container capacity (C ) = 1000 units
Safety factor (X) = 10%
The number of kanban cards required is:
- 59
- 28
- 30
- 33
2. Consider the following information:
Demand rate (D) = 200 units per hour
Lead time (T) = 12 hours
Container capacity (C ) = 144 units
Safety factor (X) = 15%
a. (*) How many kanban production cards are needed?
b. (**) How many hours worth of demand will these cards represent?
(**) Suppose the container size is cut in half. Will this make any difference in the inventory levels? Show your work.
Consider the following information:
Demand rate (D) = 300 units per hour
Lead time (T) = 4 hours
Container capacity (C ) = 40 units
Safety factor (X) = 10%
a. (*) How many kanban production cards are needed?
(**) How many hours worth of demand will these cards represent?
(**) Suppose the lead time is reduced to three hours. Will this make any difference in the inventory levels? Show your work.
Consider the following information:
Demand rate (D) = 1000 units per hour
Lead time (T) = 2 hours
Container capacity (C ) = 250 units
Safety factor (X) = 15%
a. (*) How many kanban production cards are needed?
(**) How many hours worth of demand will these cards represent?
10 cards * 250 units per card = 2500 / 1000 units per hour
2.5 hours worth of material
c. (**) Suppose the safety factor is eliminated. Will this make any difference in the inventory levels? Would this be a wise thing to do? Show your work.
Consider the following information:
Demand rate (D) = 60 units per hour
Lead time (T) = 40 hours
Container capacity (C ) = 20 units
Safety factor (X) = 10%
a. (*) How many kanban production cards are needed?
(**) How many hours worth of demand will these cards represent?
(**) Suppose the demand rate is doubled, but the lead time is cut in half. Will this make any difference in the inventory levels? Show your work.
