and 14 are $35,000 and $40,000, Copcuy.vn Bonus Problem (6 points) (Bonus points will be added to your homework score). a) A supplier of instrument gauge clusters uses a kanban system to control material flow. The gauge cluster housings are transported five at a time. A fabrication center produces approximately 10 gauges per hour. It takes approximately two hours for the housing to be replenished. Due to variations in processing times, management has decided to keep 20 percent of the needed inventory as safety stock. How many kanban card sets are needed? (3 points) b) Transmissions are delivered to the fabrication line four at a time. It takes one hour for transmissions to be delivered. Approximately four vehicles are produced each hour, and management has decided that 50 percent of expected demand should be maintained as safety stock. How many kanban card sets are needed? (3 points)

Answer 1

Question a).

D = 10 gauges per hour

L = 2 hours

S = 0.20

C= 5 gauges

K= DL(1+S)/C

K = 10(2)(1+0.20) / 5 = 4.8 Þ 5 Kanban card sets

Question b).

Demand Rate (D)
cycle time (t)
capacity at container= C
X=0.50
(N) = DT (1+X)/C
4 vehicles per hour are produced
1 hours for transmissions to be delive
sy transmission de livered to fab line
N= DT(1+X)/C
D=4
T=1
C= 4
N = 4x1(1+0.50)/4 =1.5
Number at Kanban card sets = 1.5
