Question: : Given the line balance data:

Task Predecessor Time in seconds

t none 15

u t 14

v t 7

w u 6

x v 8

y w, x 10

z y 21

a) what is the minimum and maximum possible cycle time? what is the appropriate cycle time for 8 hrs of operating time per day and a desired output rate of 960 units per day?

b) For 8 hrs of operating time per day and a desired output rate of 960 units per day, what is the minimum number of stations needed to achieve the appropriate cycle time?

c) For 8 hrs of operating time per day and a desired output rate of 960 units per day, assign tasks to stations. (Assignment rule: assume indifference)

d) For 8 hrs of operating time per day and a desired output rate of 960 units per day, what is the percentage of idle time for the balance which uses the minimum number of stations?

e) For 8 hrs of operating time per day and a desired output rate of 960 units per day, what is the efficiency for the balance which uses the minimum number of stations?
