An integrated approach to tactical logistics network optimization

Coauthors: Tobias Harks, Felix K├Ânig, Jannik Matuschke, Jens Schulz

 

Abstract:
In global logistics operations, tactic planning aims at laying the groundwork for cost-efficient day-to-day operation by deciding on transport modes, routes, and delivery frequencies between facilities in the network. We consider a fixed charge multi-commodity network flow model to optimize supply chains on the tactical level, that is, the infrastructure is already in place and we seek cost optimal transport and storage modes. Model characteristics include a frequency pattern expansion to capture the tradeoff between inventory costs and economies of scale for transport costs, as well as multidimensional commodity properties and complex tariff structures. We devise local search type and combinatorial heuristics that can be combined with mixed integer programming techniques. To evaluate the quality of these approaches we present a computational study on a set of large-scale real-world instances provided by our industrial cooperation partner. The model and the obtained results are part of the MultiTrans project, a cooperation between the COGA group at TU Berlin and 4flow AG, a market leader in logistics and supply chain management consulting.
