Rail Mounted Gantry Crane Scheduling Optimization in Railway Container Terminal Based on Hybrid Handling Mode

Abstract EN

Rail mounted gantry crane (RMGC) scheduling is important in reducing makespan of handling operation and improving container handling efficiency.

In this paper, we present an RMGC scheduling optimization model, whose objective is to determine an optimization handling sequence in order to minimize RMGC idle load time in handling tasks.

An ant colony optimization is proposed to obtain near optimal solutions.

Computational experiments on a specific railway container terminal are conducted to illustrate the proposed model and solution algorithm.

The results show that the proposed method is effective in reducing the idle load time of RMGC.
