摘要

The paper considers the operational planning task in the supply network of an Original Equipment Manufacturer (OEM), including the logistics from first tier suppliers to the assembly areas of the OEM. We propose an integrated planning approach both for the external and internal part of the network. The approach is based on a mixed-integer optimization model with a multi-commodity network design formulation. We present a generic modelling construct, which is capable of representing various tariff structures and discount schemes. These tariffs and discounts are parameters to the model and can be configured without altering the model formulation. Finally, we present a case study including numerical results for instances of practically relevant magnitude using a standard solver as well as a specially tailored heuristic algorithm.
