Container Relocation of Import Containers in Terminal Storage Yard under Uncertain Picking-up Sequences

摘要

The relocation of import containers is a key problem to reduce the reshuffle ratioand handling cost in container yard. Considering the condition of dynamic uncertain containerpicking-up time and orders, an uncertain picking-up sequence model is proposed based on thestochastic event probabilities. The Relocation mechanism of import containers is analyzedunder the uncertain picking-up sequences. A reshuffle estimate model is suggested and therelated heuristic algorithm is designed based on least-reshuffle-estimate rule. The simulationexperiments reveal that the proposed method could utilize the uncertain information ofpicking-up sequence and improve the relocation performance and the algorithm could get thesatisfied solution in reasonable time.
