Introduction • Container transport volumes are increasing considerably over time • Many operations planning models do not scale with this increase • Efficiency is gained with sophisticated decision support systems • The optimization potential of multi-modal transportation costs comes • from the possibility to choose between different transport modes • combine import and export of containers to minimize the empty tour segments • In the case of empty container re-positioning additional saving come from the different to/from location options as well as the accuracy increase of the forecast
Challenges • What is the cost optimal combination of transport modes and carriers? • What is the trade off between cost and service level? • How much equipment do I need? And where? And when? • How do I react to disruptions of the operations? How do build a robust plan? • Can I accept this transport request?
Empty Container Re-positioning Links Nodes • The model: • Input: • Network: Node and Links • Scheduled and on demand connections • Demand: Per container type • Decision variables are the choice of • Mode, carrier, time, location, number and type of containers • Constraints: • Transport capacities • Container demand for each location • Storage capacities • Business rules • Cost function to be minimized: • Transport costs • Storage costs • Equipment costs
Empty Container Re-positioning Links Nodes • The model: • Input: • Network: Node and Links • Scheduled and on demand connections • Demand: Per container type • Decision variables are the choice of • Mode, carrier, time, location, number • and type of containers • Constraints: • Transport capacities • Container demand for each location • Storage capacities • Business rules • Cost function to be minimized: • Transport costs • Storage costs • Equipment costs Linear Model ∑ size(c) ≤ cap Minimize Transport cost + storage cost + handling cost
The solution: IBM ILOG Optimization Decision Manager (ODM) • ODM is the industry leading platform for developing custom optimization-based planning and scheduling applications. • CPLEX is the leading optimization engine for linear optimization problems

Benefits of the Solution • Highly automated planning process • Exploit low-cost operations alternatives and counter-intuitive low-cost decisions • Supports strategic analysis: • Optimize the number of containers needed • Reduces the size of the container fleet • Reduced annual logistics expenses of empty container repositioning by 5 – 15% • Implemented in ILOG industry standard optimization technology • Provides an optimization platform for future solutions • Supports incremental planning to react to disruption • Fully customized to the existing IT Infrastructure, business process and requirements
Other Applications of Container Transport Optimization • Overseas container transport and re-positioning • Re-positioning of empty rail cargo freight cars: ~ 100 different types of freight cars ~ 1000 ‘nodes’ or freight train depots Scheduled cargo train connections • Container transport in the automotive industry • Forecasting of container demand
