Question 1 (20 marks): The time to perform each task, and the sequence that tasks must be completed for a processing line involving 9 work tasks (A thru l) is indicated in the table below. For this process: a. Sketch the process flow diagram (2 marks). b. Determine the cycle time (in seconds) required in order to produce 420 units over a 7 hour work shift (3 marks) c. Determine the minimum number of workstations required to achieve the cycle time determined in part (a) (2 marks) d. Using the cycle time calculated in part (a), design work stations that balance the line using the heuristic of; (i) "Assign the task with the most followers," and (ii) break ties by "Assigning the task with the longest processing time." Show all the steps involved to determine which tasks are grouped into which workstation. (10 marks) e. Once balanced, calculate the percentage idle time for the processing line (3 marks).
