I. The table below lists the work elements (in minutes) to be performed on an assembly line and the precedence requirements that must be satisfied. Annual demand for the product will be 60,000 units. The line will operate one shift (2000 hr/yr). Expected line efficiency (proportion uptime) is 95%. Repositioning time per cycle is 6 sec. Manning level is 1.0 for all stations.
solve the line balancing problem using the RPW method.
| Work element | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| Time (minutes) | 0.5 | 0.3 | 0.8 | 1.1 | 0.6 | 0.2 | 0.7 | 1 | 1.2 | 0.4 | 0.9 | 0.1 | 1.3 |
| Preceded by | - | - | 1 | 1,2 | 2 | 3 | 4 | 5 | 5 | 6 | 7 | 8,9 | 10,11,12 |
