Question: There is an assembly line balancing problem with nine tasks (A, B, C, D, E, F, G, H, and I) to be assigned to workstations,

There is an assembly line balancing problem with nine tasks (A, B, C, D, E, F, G, H, and I) to be assigned to workstations, with intent to minimize the idle time, given the throughput rate of 275 units per day and 440 minutes of available time per day. Task IDs and processing times (in minutes) with their precedence are given below: A(0.4)>C(0.3)>E(0.2)>G(0.1)>H(0.5)>I(0.3). There is an additional sequence of tasks: B(0.6)>D(1.2)>F(0.6), feeding into the task H. So the assembly line efficiency is close to:

a) 70%

b) 50%

c) 90%

d) 60%

e) 80%
