Abstract

Production scheduling and vehicle routing are both well known and widely studied problems within the field of operations research. However, in many practical settings a supply chain consists out of a sequence of different stages that all require some scheduling or routing. Rather than just optimizing the planning within each stage separately, a good synchronization between the different stages is crucial to prevent inefficiencies or infeasibilities. Especially when there is none or limited storage capacity between subsequent stages, bad synchronisation might lead to delays or even deadlocks. An integrated solution method is required to prevent this and obtain good synchronization over the entire supply chain. We propose a general framework for modelling such multi-stage problems and compare different integration strategies

The issue of multi-stage scheduling problems with limited intermediate storage especially arises for industries that are making a transition from make-to-stock towards make-to-order. A good example is the compound-feed industry, where storage is usually designed for large quantities of universal products. Due to changing customer requirements, the production changes more and more towards small quantities of many different personalized products instead. Since intermediate storage is not suited for this, this increases the need for good synchronization between production and transportation. We also provide results based on realistic data from this industry
