(6) What is the minimum theoretical number of workstations required if the cycle time is assumed to be 20 minutes? (C) Assuming a cycle time of 20 minutes, balance the line by the ranked positional weight method, and • Show the workstations on the precedence diagram. • Determine the idle time on each workstation. • Determine the layout of workstations (flow of material through the workstations)
