Question 2: [30 Marks] A company is introducing a new model of 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 15 minutes. You are required to: a. Draw the precedence graph. You should use arrows to connect tasks. b. Calculate the minimum possible number of workstations (Nmin) required. [3 Marks] c. Assign tasks to stations by using the longest processing time decision rule. In case of a tie, use the tiebreaker to assign the task with the largest number of following tasks. [10 Marks] d. Draw the product layout with the assignment of tasks into each workstation. [ 3 Marks] e. Determine the efficiency of the process. [2 Marks] f. Is the product layout obtained from part c optimal? Explain if it is or it is not. [2 Marks] g. Compute the rate of output that could be expected for this line assuming a 480 -minute working day. [2 Marks] h. If the task time of Task B is reduced by 1 minute from 7 minutes to 6 minutes, keeping the designed product layout and the operating time unchanged, what will be the effect on the maximum possible system efficiency and daily output?
