A Stochastic Model of Empty Container Transport on Sea

Abstract

A chance-constrained programming model for empty container transport on sea c is built. The objective function is to minimize the cost of empty container transport including shipping, renting and shortage cost. In the model, shipping cost is determined by the number of ship used for empty container transport. The constraints to the model include satisfying the need of empty containers, limit to the ability of empty containers provided and the capacity of transport. Lingo9.0 is used to solve the model and simulation is done under varied parameters to better transport 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.
