Francis Johnsons plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 12 units per hour, and there is room for only five workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task. TASK TIME IMMEDIATE TASK (MINUTES) PREDECESSOR 2.5 2.0 2.0 3.0 3.0 3.0 3.0 A,B, C b. What is the workstation cycle time required to produce 12 units per hour? (Round your answer to 1 decimal place.) Workstation cycle time d. Balance the line to use the fewest possible workstations to meet the cycle time found in part b. Use whatever method you feel is appropriate. What is the efficiency of your line balance, assuming the line minutes operates at the cycle time from part b? (Round your answer to 1 decimal place.) Efficiency

Answer #1

b) Workstation cycle time = Available time/ Demand rate = 60 minutes / 12 units = 5 minutes
