Consider the following 10-stage sequential manufacturing process, where each process is performed by a specific machine. You intend to develop a U-shaped flow line containing the machines required for this process.

Process Mean Processing Time 1 10 2 15 3 10 4 30 5 50 6 30 7 10 8 15 9 25 10 45 Initial plans have allotted four workers to the cell. Allocating the workload to each worker evenly, in terms of processing time, draw the arrangement of the workers in the flow line and identify any potential problems.
