Answer:
Two Kanban cards is needed
Step-by-step explanation:
Solution
The first step to take is to compute the required Kanban number of card sets.
By applying the formula, we have the following
Kanban cards = DL (1 +S)/C
Where,
L = The lead time to replenish an order is 1 hour
K = The number of kanban cards
D = The average number of demanded unit per a period which is 4
C= the container size which is 4
S = The safety stock represented in percentage of demand 0.50
Now,
We substitute the given values in the above formula and compute the number of kanbabn cards as follows:
Kanban cards = 4 * 1 (1 + 0.5)/4
= 6/4 =1.5
Therefore, the number of Kanban card sets are needed is 1.5
