For the in-line skate assembly example in this chapter, suppose the times for the individual operations are as follows:
TaskTime (sec.)
1...........20
2...........10
3...........30
4...........10
5...........30
6...........20
7...........10
8...........20
Assume that inspections cannot be performed by production personnel, but only by persons from quality control. Therefore, assembly operations are separated into three groups for inspection. Design a production line to achieve an output rate of 120 per hour and 90 per hour.
