Task Task Time Immediate Predecessor Positional Weight A 5 - [pwA] B 10 A [pwB] C 5 A [pwC] D 15 B,C [pwD] E 5 D [pwE] F 15 D [pwF] G 5 E [pwG] H 10 F,G [pwH] (a) (6 points) Calculate the positional weight for each task (add to table above). (b) (6 points) Assign tasks to workstations according to the Ranked Positional Weight (RPW) heuristic. If a workstation is empty, just put N/A in the box. Workstation 1 tasks: [ws1] Workstation 2 tasks: [ws2] Workstation 3 tasks: [ws3] Workstation 4 tasks: [ws4] (c) Answer yes or no to the following questions. (2 points) Does task C dominate task D? [cd] (2 points) Does task B dominate task C? [bc] (2 points) Does task F dominate task E? [fe] (4 points) Did the RPW heuristic produce the optimal line balance? [opt]
