Integrated Scheduling Model for Cranes, ASC and SP-AS/RS in Automated Terminal

This paper establishes a mixed integer programming model for the integrated scheduling problem of quay crane(QC), automatic straddle carrier (ASC) and split-platform storage/retrieval system(SP-AS/RS), the objective function of the model is the sum of the minimum working time of ASC, SP-AS/RS and the minimum delay time of QC. The model is solved by an improved genetic algorithm(IGA), which objective function solution is compared with the corresponding model using AGV, the comparison results are analyzed in different scales. The quality of the solution of IGA and SAA was compared by simulation experiments, which verified the effectiveness of IGA in different scales.
