Abstract:

In this article we compare two apparently dissimilar scheduling problems. The Small Batch Assembly Line Balancing problem is the process of dividing operations over multiple stations so as to produce a series of parts whose processing times are characterized by learning. The Lot Streaming in a Flow Shop problem is the process of splitting a given lot or job to allow overlap of successive operations in multi-stage production systems, thereby reducing the makespan of the corresponding schedule. We show that the two problems are formally equivalent. By exploring the mathematical equivalence of the two problems, a number of unexpected new results have been obtained.
