Regardless of the number of tasks or their durations, a line balance that is 100% efficient is achievable if CT = ΣT_i.

Question

Quizplus · Accepted Answer

This formula represents the theoretical maximum efficiency of a line balance, known as the "perfect balance." CT (cycle time) is the maximum time allotted for completing one unit of production. ΣT_i represents the sum of task times, multiplied by their respective cycle time, workday utilization factor, batch size, and work factor, for all tasks on the line. Achieving this balance would mean that each work station on the line is being utilized to its full efficiency and there are no idle workstations, resulting in a 100% efficient line balance.
