A manager wants to assign tasks to workstations as efficiently as possible and achieve an hourly output of 31 units. Assume the shop works a 58-minute hour. Assign the tasks shown in the accompanying precedence diagram (times are in minutes) to workstations using the following rules:

a. In order of most following tasks. Tiebreaker: greatest positional weight. (Round your answers to 1 decimal place. Due to worker constraints, only 2 tasks will be assigned to workstation II, even if sufficient time remains for a third task. For task, enter a letter between a and h in lowercase with no other text or symbols.)

b. What is Cycle time? (Round down your answers to 1 decimal place.)

c. What is Efficiency? (Round your answer to 1 decimal place.)
