There is no bufferīetween QCs and YTs or YTs and YCs, thus the equipment scheduling is Tasks of inbound and outbound containers alternately. Time of empty movements of YT by making the YT perform the transporting In container terminal, the dual-cycle operation can decrease the However, the integrated scheduling problem of various types ofĮquipment in container terminal using dual-cycle mode still was not Improve the efficiency of QCs and to shorten the turnaround time of The containers operating sequence problem, and the objective was to Meisel adopted dual-cycle mode to minimize the inboundĪnd outbound containers operating time in the bay by optimizing the Ship-bay, which was equivalent to maximizing the number of dual cycle Integer programming mode for discharging and loading containers in a Last-loading or loading outbound containers, without taking dual-cycleĪs to the dual-cycle operation, Goodchild described theĭouble-cycling problem, and gave a solution in order to reduce the They only concentrated on it in the operation mode of first-unloading Scheduling problem of various types of equipment in container terminal, Although literatures above focused on the integrated NN was mainly used for predicting individualĪdaptive function. The optimization method was a mixed algorithm of Terminals, and adopted simulation optimization to solving the integrated Hybrid flow shop to simulate the operating system of container Multi-type equipment with tabu search (TS). Hybrid flow shop, and she solved the integrated scheduling problem of Chen described container operation system as 3-stage Problem of various types of handling equipment used at container There are few literatures focused on the integrated scheduling Of container operation system suing dual cycle operation. Problem of container terminal operation system and equipment scheduling Here, we provide only aīrief review of previous studies related to the integrated scheduling Gave comprehensive reviews of studies above. Bierwirth, Stahlbock, Steenken and Vis
Traffic flow controlling, description and evaluation of logistics system Terminal are concerned on berth allocation, container stowage, containerĭeployment, slot allocating in yard, equipment deploying and scheduling, Studies associated with production organization in a container Paper, we only pay attention to the integrated yard truck, quay craneĪnd yard crane scheduling problem in container terminal with dual-cycle To inbound and outbound container flow existing simultaneously. Scheduling of YTs, stowage of vessel and cooperation among equipment due The dual-cycle operation brings higher requirements for the
The dual-cycle operation, because of the reduction of empty movement of Then the QC discharges an inbound container from vessel's currentīay and loads it onto the YT. The outbound container reaches the quayside, QC picks off the containerįrom the YT and loads it onto the planned slot on the containership and Shows the process of dual-cycle operation. In recent years, the dual-cycle operation has been extended. Start to use new handling technology which can reduce the empty movement Order to improve efficiency of container terminal, more harbour bureaus But YT performing transportation task must make anĮmpty movement to the quay area or to storage location in the yard. Since there is always one-directionalĬontainer flow, managers can arrange equipment scheduling and yard There onlyĮxists outbound container flow. Will finally load the container onto the containership. The YT then transports the container to a QC, which There only exists inbound container flow (2) after finishingĪll loading tasks, YC picks up an outbound container from stack and Yard and a yard crane (YC) in the yard picks off it from the YT and The YT then transports the container to a container Picks up an inbound container from the containership and loads it onto a Operates as follows: (1) when a vessel docks and berths, quay crane (QC) 1 shows a typical layout of container terminal.
