All jobs (cars requiring detailing) must first be cleaned, then waxed. a. What processing sequence will minimize the makespan for these jobs? Job | Cleaning Time time | Cleaning Time end time | Waxing time time | Waxing time end time | Waxing time idle time | C4 | 3 | 3 | 5 | 8 | 3 | C3 | 5 | 8 | 7 | 15 | 0 | C1 | 9 | 17 | 6 | 23 | 2 | C5 | 8 | 25 | 4 | 29 | 2 | C2 | 6 | 31 | 2 | 33 | 2 | b. What is the minimum makespan for this set of five jobs? Makespan is 33 (POM SW output is attaced in excel) 42. (10 points) The elements required for successful implementation of the JIT/Lean philosophy include reducing setup times, performing preventive maintenance, and achieving high quality (zero defects). Discuss the problems that might arise when a kanban system (pull system) is used for production control and each of these JIT elements is not present. (In other words, what would happen if a kanban system is being used and there are long setup times, no preventive maintenance, and poor quality?) If Pull type Kanban is used & the mentioned issues in the question above are faced, below will result. Longer setup times will lead to increase in inventory levels as the raw material can’t be processed till setup is complete. This can lead to deterioration of...
