Coordinated Optimization Of Continuous Berth Allocation And Quay Crane Dispatch For Double Ports Considering Vessel Emissions

After entering the new normal,China will pay more attention to green economy and sustainable development.While the ship's carbon emissions has been an important reason for air pollution in the coastal city."Low-carbon shipping construction" will be the focus of work during the thirteen five.Firstly,this paper studies the relationship between fuel consumption and speed,and quantifies the carbon emissions of ships as direct proportion to the three side of the speed.At the time,the theory of boxing problem is also studied,and the problem of berth and quay bridge optimization is abstracted as packing problem.This paper takes ship speed selection,berth allocation and quay crane dispatch as the research objects,and takes into account the dynamic arrival of the ship,the continuity of the berth and the priority of the berthing of the ship,which are more in line with the actual operation of the port.This paper bases on the theory of optimal allocation of container terminal resource and ship speed,takes minimized ship delay time and carbon emissions,and integrates the ships,berths and quayside as a system.The paper builds the Double Ports Model of Coordinated Optimization of Continuous Berth Allocation and Quay Crane Dispatch Considering Vessel Emissions based on assumptions.Because of deficiency of particle swarm algorithm in solving discrete problems,this paper applies the genetic algorithm and plant growth algorithm to improve it,and designs a new algorithm called Multi-objective HybridParticle Swarm Optimization Algorithm Based on Plant Growth and Genetic Algorithm.The algorithm inherits the advantages of three heuristic algorithm,and the experiment proves that it has good convergence and global search ability.Finally,the HPSO is used to solve the model,and a smooth Pareto optimal frontier is obtained and a number of optimal schemes are provided to the decision maker.As a result,we reach the purpose of optimizing the allocation of resources and improving service of port,and ultimately improving the core competitiveness of the port.At the same time,we reduce carbon emissions by ship,and increase the environmental benefits.There's great significance in berth-quay crane coordinated optimization and low-carbon shipping construction.
