Research On The Intelligent Dynamic Planning System Of Tianjin Port Based On Genetic Algorithm

With the development of tianjin binhai new area and the northern international shipping center construction,tianjin vessel traffic with the rapid growth of navigation ability has become increasingly saturated,become the bottleneck of restrict its further development.To this end,tianjin port for constructing the compound channel is put forward.Compound channel is channel at the same cross section,at the same time,there are two or more different design depth of the water channel or fairway.Completion of tianjin port compound channel,the big boat will be running at ten thousand tons to shunt,heavy traffic when there will be four strands of traffic flow on channel at the same time,ship in the clearance process may appear more than meeting points and cross waters,avoid high-risk for tianjin VTS center,this will further increase the difficulty that navigation safety regulation.As tianjin port the regulators and the use of the safety of compound channel,and tianjin VTS center proposed joint tianjin port group,pursuant to the rules of double entry navigation safety management to develop a set of tianjin port intelligent dynamic planning system,production planning simulation to generate traffic flow through the port group,real-time test the layout plan of navigation safety,in order to ensure the safety of navigation of ships under the premise of improving the efficiency of the ship,or navigation.This paper mainly completed the following work:1,based on one-way channel port ship scheduling model is constructed.First of all,the enterprise of tianjin VTS center and the wharf has carried on the on-the-spot investigation,and on this basis,the further study of the port the core of the ship scheduling problem and internal mechanism.Then,in view of the port enterprise and the shipping company different interests appeal design objective function respectively.Finally,from the Angle of the traffic flow of the ship scheduling process carried on the thorough analysis,according to the different parts of the port traffic flow characteristics of the scheduling process is divided into multiple child process,for each child to build the initial model,flow transformation model,time slot allocation model and berth conflict resolution model,and then build a complete port ship scheduling model.2,design a ship scheduling optimization based on one-way passage multi-objective genetic algorithm(ga).Will berth conflict resolution model into coding rules,this paper proposes a berth conflict resolution algorithm,and then design the coding operator: transform flow model and the time slot allocation model into decoding rules,this paper proposes a from genetic space to the solution space of the algorithm.3,through the analysis of the system goal and task,the design including the Web server,GIS server,database server and browser CS/combined with B/S structure,system functions including data conversion,Intranet data reported data,the network performance,integrated platform Oarcle databases and access control.4,based on the analysis of channel management,on the basis of comprehensive data,combined with the characteristics of GIS data processing,make full use of GIS and efficient spatial data and attribute data maintenance ability and powerful query retrieval function,realizes a channel integrated information platform for the GSI performance,including the creation,space navigation electronic map data display,query,output,can make the system according to the needs of users,reflecting the channel system of point(such as the observation point,a point,beacons,bridge,wharf,etc.),line(such as channel,etc.),surface(such as administrative divisions)involved in the relevant information.5,through the construction of tianjin port intelligent dynamic planning system,objective truly reflect the state of traffic flow in compound channel possible risk,convenient departments formulate corresponding security in time,effectively improve the efficiency of production planning,thus effectively protect the safety of tianjin port shipping unobstructed,increase the productivity of the port channel.6,intelligent dynamic planning system through the establishment of tianjin port,tianjin port group daily production planning simulation to generate the ship traffic flow,according to the regulations of tianjin VTS center on compound navigation safety rules for real-time navigation safety of the plan,to calculus was not by plan,system can be automatically recommended plan adjustment Suggestions.Development of this system is in order to ensure the safe navigation of tianjin port channel high-risk area area and effective regulation,and also provide the conditions for the realization of the port economic benefit of ascension.For the former,this project is public welfare undertakings,it mainly embodied in the social benefits.Through the implementation of this project,can effectively strengthen the vessel traffic management,maintain good traffic order,improve Marine traffic safety,to prevent ship accidents,and thus to reduce casualties,ship and cargo damage.In terms of economic benefit,as the system put into use,tianjin port will achieve greater compound channel \ "double in double out\" traffic organization mode,enables size vessels in and out of the port in time,thus improve the channel utilization,berth utilization rate,reduce the ship waiting time,enhance the port competitiveness.
