The Study Based On The Witness Qinhuangdao Port Coal Yard Operation Optimization

With economic globalization and the development of modern logistics, harbor transports tend to develop fast. As a global transport network node, the ports highlight the Logistics efficiency. Port managers focus more on the loading and unloading efficiency of dock. And ignore the yard management. With the increase in throughput of the port, they have realized Internal Port Logistics Operation is important to the development of the port; particularly the port container yard operations have an import of the efficiency of the port. Whether the operations are easy and smooth or not is directly related to the stock of port yard and the satisfaction of the customers.First, research background and significance are proposed. We have summarized and analyzed the research status and research purposes of the domestic and foreign research scholars to the port container yard operations. Most of them concentrate in the port or the port logistics system for research. They research the port container yard operations very little. So research content and research method are put forward in this paper.Second, the coal port yard, the port yard operations and the theory about the yard operating optimization are introduced. And the yard operating optimization are explained by using combinatorial optimization theory, heuristic algorithm and multi-programming method.Using discrete event simulation, and qualitative and quantitative method of combining According to the analysis to the complex environment of the port container yard operations,put forward Yard operations optimization principles and use the superiority of the WITNESS simulation software to establishes the foundation for the optimization model and emulation research of the port container yard operations for this paper.Once again, according to the port container yard operations Process of the coal, we put forward the optimization principles of the yard operations and optimizing performance indications and set up the optimization model of the port container yard operations, build a simulation model of the port yard operations by using WITNESS simulation. Besides, we put an emphasis on the analysis to the stacker feeder operation time, utilization ration and so on in the yard. Testing the simulation model reduces the pressure on the port yard stockpiling.At last, we strengthen the importance of the port container yard operations in the port, bring in the advanced technology, improve the port container yard mechanized operations, coordinate the relationship between the port container yard operations and other departments, highlight the differences among the port service and upgrade the port power.
