Job sequencing for 3 work stations in series (SKED3A)

SKED3A are designed for flow shops of 3 work stations arranged in series. Each job receives exactly the same processing at each station. In such flow shops, there is no attempt to minimize lateness; instead, the objective is to minimize the total time needed to complete a batch of jobs.In both SKED2A and SKED3A, there may be several alternative optimal solutions. Depending on how the jobs are sequenced before running the Ctrl – Shift – J macro, the worksheet may generate different sequences with the same makespan.
