Question

can someone help me with this:

As Patrick Sportwear Co. completes plans for its new assembly line in Liverpool, it identifies 30 different tasks in the production process. VP of Operations Kevin Keegan now faces the job of balancing the line. He lists precedences and provides time estimates for each step based on work-sampling techniques.

His goal is to produce 1.000 football shoes per standard 35-hour workweek.

Task	Time (sec)	Immediate Predecessors	Task	Time (sec)	Immediate Predecessors
B1	50	-	E2	18	G5, F3
K4	24	B1	A4	10	E1
K9	27	B1	E3	109	F3

1A) Balance this operation using the shortest operation time rule and compute the efficiency of the line.

first create a precedence diagram.

2B) Second: Balance the operations using the given heuristic.

here is the table.

Work Station	Eligible Task(s)	Assign Task	Task Time	Time Remaining

Third: Identify the efficiency of the operation's balance and explain/justify your answer
Fourth: Explain the process followed, observe and criticise your answer.

i have found some answers on bartleby for this question like for the precedence diagram but it looked different to the one i am supposed to create as shown in the picture and for the other question i coundt find anything.
