Optimization Scheduling Model of Double Line Shiplock Based on Nonlinear Goal Programming
The scheduling method of shiplock has a strong influence on the improvement of shiplock capacity. On the condition that the number of the ships waiting for the lock was relatively stable, the paper constructed an optimization model for joint scheduling of double line shiplock based on the nonlinear goal programming. The hard constraints included that the number of ships arranged in the shiplocks couldn't exceed the number of the ships waiting for the lock. The soft constraints included arranging the ships with the priority and time limit as far as possible, and maximizing the utility of the lock chambers. Then the objective function was constructed. Considering the characteristics of the nonlinear goal programming mode, the Hooke - Jeeves algorithm was used to solve the model. In the end, a double line shiplock of Jiangsu province was taken to verify the scientificity and feasibility of the model.
