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

$110$

$215$

$310$

$430$

$550$

$630$

$710$

$815$

$925$

$1045$

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.
