Lot splitting is the practice of dividing an order into smaller batches when the job is released to the production system. Although splitting may improve flow times, it may also increase the number of setupls and material handling costs incurred. This paepr shows that variability in processing times across operations can cause the performance of lot splitting schemes to degrade significantly. However, it also shows that the use of rules which dynamically trigger the splitting and re-joinging of lots throughout a job's routing can retain much of the benefit of lot splitting while decreasing the disadvantages.
