Question 2 (Layout) (30 marks] A toy manufacturer is introducing a new model of toy car and needs to balance the process for its new assembly line, given the following task times and precedence relationships. Assume that the cycle time is 13 seconds. Task Time (seconds) Immediate Predecessor D, F, G You are required to 1. Draw the precedence graph. (3 marks) 2. Assign tasks to stations by using the longest processing time decision rule. In case of a tie, use the tiebreaker of assigning the task with the largest number of following tasks. (15 marks) 3. Determine the efficiency of the design of the product layout from item(2). (3 marks) 4. Draw the product layout. (3 marks) 5. If the manufacturer wishes to keep the current design of the product layout and improve the daily rate of output, is it feasible and how? What will be the new daily output rate and efficiency of the product layout? Assuming for this production line the working time is 480 minutes per day. (6 marks)
