Under the ranked positional weight method of line balancing, how is the positional weight of a task calculated?

In the ranked positional weight method, a task's positional weight is its own time plus the times of all tasks that follow it in the precedence diagram. Tasks are then ranked from highest to lowest weight and assigned to stations in that order, subject to cycle time.

  1. AIts own time plus the times of all tasks that follow it in the precedence networkCorrect
  2. BIts own time minus the times of tasks that precede it
  3. CIts own time divided by the cycle time
  4. DThe number of tasks that immediately follow it

Explanation

Positional weight is the task's own time plus the times of all successor tasks. Tasks are ranked in descending order of weight and assigned to stations accordingly. The other options describe unrelated measures; the successor-count option belongs to a different heuristic.

One question tells you little. A timed set on Simulation and Line Balancing shows your real accuracy, how long you take and where you lose marks.
