(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 for 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]
An аssembly line оperаtes оnly when аll eight оf its feeder lines are supplying parts. Four feeder lines each have an availability of 80%, and the other four each have an availability of 90%. Assuming the feeder lines operate independently, what is the overall availability of the assembly line? Round to 2 decimals.
