Which one of the following statements about line balancing is best?
A) If a precedence relationship exists between A and B, they cannot be assigned to the same station.
B) If the desired output rate increases, the cycle time also tends to increase.
C) The theoretical minimum number of stations can never be achieved, hence the name "theoretical."
D) If a line's balance delay is minimized, its efficiency is maximized.

Question

Quizplus · Accepted Answer

Line balancing involves assigning tasks to workstations in a way that minimizes imbalance, which is known as balance delay. By minimizing balance delay, efficiency is maximized. Therefore, option D is the best statement. Option A is incorrect because precedence relationships do not necessarily prohibit tasks from being assigned to the same station, as long as the station can perform the tasks in the correct sequence. Option B is incorrect because as output rate increases, cycle time usually decreases in order to produce more units in a given time frame. Option C is incorrect because the theoretical minimum number of stations can be achieved if tasks are assigned correctly and there are no constraints on the process.
