7. In the Colpitts Control Devices workload balancing problem presented in this chapter a successor task could be assigned to the same workstation as an immediate predecessor task. Suppose we change that assumption so that a successor task cannot be assigned to a workstation containing an immediate predecessor task. a. What change is required to enforce this new restriction? b. With that new restriction in force, solve Colpitts workload balancing problem to determine the minimum cycle time with 1, 2, 3, 4, 5, 6, 7, and 8 workstations and produce a graph of the results like the one shown in Figure 6.27. c. Explain how and why your results differ from those shown in the graph in Figure 6.27.
