A production line is to be established to produce 300 modems per day (460 minutes).

The production tasks, their times, and their precedence requirements are shown in the table below.

(a) Using a heuristic that assigns the longest available task that will fit within the remaining work station time, assign the tasks to the minimum number of work stations required to meet the cycle time.

(b) Determine the efficiency of the line.

(c) How might the balance be improved?
