A Heuristic for Multi-Product, Multi-Period, Single-Level Batch Production

We describe a heuristic procedure for solving multi-product, multi-period, single-level batch-production problems. The method consists of two procedures for a lot-sizing problem with capacity constraints for time-varying demand and a job-shop machine-scheduling problem for given lot sizes, which are applied in succession. We also discuss the performance of the priority rules of the Giffler-Thompson algorithm for solving the job-shop problem.
