Optimization of Empty Container Repositioning of Sea Carriage

摘要

An optimization model for empty container repositioning of sea carriage is established by integer programming for shipping companies to improve the efficiency of empty container shipping. The objective function is to minimize the cost of empty container repositioning including shipping , rening and. shortage cost. In the model, shipping cost is decided by the number of ship used for empty container repositioning. The constraints to the model include meeting the need of empty containers, limit to the ability of empty containers provided and the capacity of shipping. Lingo9.0 is used to solve the model and simulation is done under varied parameters to get a good shipping strategy. The results show that the model can provide an effective program of empty container repositioning for a shipping company and it is a good way to raise shipping efficiency.
