A Molding Study Of Bonded Port Customs Door Area Based On Discrete Event Simulation

With the process of economic globalization and regional economic integration speeding up,the status of bonded port in the global economy is increasingly enhanced and plays a bigger and bigger role in the regional economic competitiveness.Bonded port customs door,a checking station for customs operation,set up on the road of bonded port,contains customs door on-ramp,roads nearby,inspection hillock of door,customs inspection place at port,with complicated transportation and logistics,which is hard to establish simulation model with lower efficiency.At the same time,the customs door controlled by customs, whose checking efficiency would affect the transportation and its resource allocation further has an influence on the operation efficiency of the whole bonded port.This research focuses on the simulation modeling of the customs door.This thesis mainly makes a research on the customs door area of the transportation system of the bonded port,aiming to improve the customs door operation efficiency of the bonded port,taking a search on the simulation modeling and optimizing methods of the discrete event.The paper makes an analysis on the features,constitution,and special process of the customs door logistic system of bonded port,wholly on the logistic system of customs door of bonded port;and then,it also states systematically the simulation optimizing theory of the discrete event system,the basic concept and simulation steps,random distribution characteristics,random factors and random variables,making a basis for applying witness to take modeling research;in chapter 4,the thesis builds up the logistic model of the customs door based on the witness,and introduces the simulation software and mentions the achievements of simulation models,later the systematic statements of customs door and operation flow analysis,finally the general build-up of the simulation model and the realization and inspection of the model;in chapter 5,paper introduces some of China's coastal port,from the Angle of the examples,based on the Witness has established its customs bayonet socket simulation model of logistics,and discourses the model's checking and optimizing methods through specific examples,providing settling plans for the optimization of the logistics systems of bonded port from the angle of the customs door;in chapter 6,it comes into conclusion of the research and prospects for the future research.The significance of the research is the combination of the computer methods of simulation and the actually complicated dynamic system of discrete events.Through the simulation model that port logistics system combined customs facilities and process optimization method.Meanwhile,the simulation and optimization theory pertinently applied to port logistics system combined customs setting and resources provided an effect method for the available and balanced use of resources,combined with the actual operation process of the customs door of bonded port,which is significant to the contribution of our country's bonded ports.
