Statistical Evaluation And Analysis Of Berth Assignment System In Container Terminal

With the development of modern logistics, port managers are increasingly aware of the importance of improving terminal operation efficiency of logistics. Container terminal operation system has become the hotspot to research. Berth assignment system is an important part of container terminal. Improving the efficiency of berth assignment system can greatly improve the service quality and the operation efficiency of port. The designated ways of berth, the service strategies for vessels, and the allocation ways of quay crane are the important factors to improve the operation efficiency of port and the operation efficiency of vessel. So researching the berth assignment system has important practical significance.The thesis considers two kinds of berth circumstances which are the discrete berth and the continuous berth. The berth system is simulated and statistically analyzed and evaluated. Firstly establish the evaluation index system to describe the designated ways of berth, the service strategies for vessels and the allocation ways of quay crane. The evaluation index system mainly includes four indices which are berth utilization rate, quay crane utilization rate, the vessel average waiting time and the vessel operation rate. Then use Monte-Carlo method to simulate the different operation ways and gain the simulation data of the index values. And analyze the data by using the variance analysis and sensitivity analysis. Lastly present the optimal operation way of berth assignment system according to the differences of index values. The optimal operation way will help the operators of the port to make a correct decision.
