[5] ) Two jobs must be processed through four machines in the given sequence. The processing times in the required sequence are in the table 2(c). Table 2(c): Sequence and processing times Job-1 Job- 2 Machine Time Machine Time A 5 A 2 B 4 B 4 6 D 3 D 3 C 5 (i) How do the jobs should be scheduled in order to minimize the total make span using Aker's rule? Show them in the graph paper. Draw the Gantt chart in graph paper indicating the optimal schedule. If you need to add a third job, how do you apply Aker's extension? (ii) (iii)
