Abstract: Container shipping of sea-carriage optimization is an important way to effectively enhance the competitiveness of shipping companies’ efficiency. The optimization model of container shipping of sea carriage based on chance-constrained programming is established to maximize the profit of a shipping company, which is the objective function. The variables include the number of heavy and empty containers shipped by lines, the shortage number of heavy containers, and the renting number of empty containers from requiring ports to meet the demand. The constraints include meeting the requirements heavy and empty containers, weight and volume limit to lines, and supplying ability for empty containers. The number of empty containers supplied is stochastic for being affected by several factors. The chance-constrained programming is translated into an integer programming, and the Lingo 9.0 is used to solve the model. Simulation is conducted under varied parameters to show the effectiveness of the model in optimizing the shipping plan. The model can be used to optimize container shipping plan of sea carriage to a shipping company and get profit raise.
