Abstract:Economic globalization has further promoted the foreign trade relations between countries, and thus accelerated the development and growth of maritime transport. With the continuous reform and development of port logistics, containers has become an indispensable mode of transportation in the shipping system, therefore, the management of containers is also becoming more and more complicated. This paper discusses the layout of logistics companies’port containers, and according to the uncertainty of container delivery at container yard, based on the factors that affect the storage of import and export cases, a model of container random access to yard with different weight and different packing port is established, which helps achieve the minimum number of cases before shipment, thereby greatly improving the efficiency of shipment.
