2.23. An assembly line is being designed. Each station will have one worker. Cycle time for meet ing demand is 40 time units. Using the data in Table 2.11 find an optimal (minimum number of workstations) solution. A zoning restriction exists such that tasks d and must be performed in the same workstation. If your solution has more than 10 percent idle time, suggest alternatives the could be explored to improve efficiency. What ad- ditional data would be required to analyze these alternatives?

If all stations must complete their tasks with a probability of 0.95, what is the line balance task/station assignment? Comment on other approaches to address processing time randomness
