Answer: 2 Vats will be used
Explanation:
using the formula below, the ideal number of Kanban cards can be calculated;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, in the question, we were given that;
D = 204 pounds per day = 204 / 8hrs = 25.5 pounds/hr { The plant operates on an eight-hour day}
T = 2.25 hrs
X = 0.17
C = 34 pounds each
we substitute
N = (25.5×2.25 × ( 1 + 0.17)) / 34
N = 67.12876 / 34
N = 1.974375 ≈ 2 Vats
Therefore 2 Vats will be used.
