A small electronics company assembles power supplies for use in computers, printers and FAX machines. They want to set up an assembly line to make their operation more efficient and plan to use
line balancing with the incremental utilization heuristic. The demand for power supplies is 150 per hour, and the productive time per hour is 45 minutes. The following table provides details on their operation (with time in minutes):
| Time to Perform Task | Task that must immediately precede |
| A 1.12 | — |
| B 0.68 | A |
| C 0.22 | A |
| D 0.18 | A |
| E 0.86 | B,C |
| D 0.18 | A |
| E 0.86 | B,C |
| F 0.44 | D |
| G 1.24 | E |
| H 0.70 | F,G |
| I 0.42 | H |
| J 1.14 | H |
| K 0.66 | I,J |
