The Combined Scheduling Of Berth And Quay Crane At Container Terminal

The development of the global economy has led to the prosperity of the logistics industry.As an important node of logistics,ports play a key role in the development of logistics industry.Container transport has grown rapidly,with large volumes of containers flooding into ports,causing ships to stay in port.This has prompted port operators to consider how to allocate port resources more rationally to maximize economic benefits.One of the most critical part is how to assign the reasonable berth and quay crane to the ship to the port.While berth resources restricted by natural conditions and quay crane is the most expensive port resources,only consider the existing resource constraint conditions more reasonable arrangement and control the two resources has more practical meaning.This article is based on continuous berths and gantry cranes coordinated scheduling problem and establishes the optimization model of the target ship to minimize the time in port and to minimize the cost of work.And according to the model,this paper designs a multi-objective genetic algorithm.Finally,combined numerical example,effectively shorten the time of the vessels in the harbor,and reduce the cost.The main contents are as follows:Firstly,simply introduce the theoretical and practical significance then based on the existing theoretical results this paper introduces the basic concepts and theories related to berth allocation and quay crane assignment,which lays the foundation for follow-up study.Secondly,after assumptions and parameters this paper builds a double target model which both considers time and cost and then designs a multi-objective genetic algorithm and introduces process and applicability.Finally,a case is used to support the effectiveness of the model and algorithm which provides references for container terminal.Summarize this paper and shortcomings.
