Study On The Optimized Of The Container Terminal Yard Operation Equipment

In the wave of economic globalization, the international trade has increased sharply. Container transportation with its own advantages has also obtained fast development and improvement. In order to meet the customers’ need and improve the operational capacity and services levels of the pier, container ports are constantly seeking the use of modern technology and new and efficient loading and unloading equipments. Therefore, the selection of equipment and loading and unloading process arrangement are facing the challenges of the new situation.In this research, the working process of the container terminal yard, and the types and characteristics of the loading and unloading machinery are investigated. And the factors, such as container yard working process, loading and unloading machinery type, loading and unloading technology form and so on, that affect the container terminal yard layout are analyzed. After examined a large amount of literature and research findings, this paper puts forward new theories on the container terminals yard equipment type selection and loading and unloading technology. Based on the operating characteristics of the container terminals, as well as the specific operation of the equipments, the new theories combine the current status quo of the container yard equipment selection, comprehensive consideration of the mechanical efficiency, economic cost and environmental factors. In comparison with the previous selection scheme, this paper not only involves the quantitative factors such as cost and efficiency, but also introduces the qualitative factors such as the flexibility of the loading and unloading technology, environmental impacts, equipment operation and maintenance issues. Therefore, the Fuzzy Analytic Hierarchy Process combing with the expertise experiences and quantitative analysis are used in this paper to identify the optimal solution of the selection model. Finally, the case of the upcoming specialized container terminal project which located at the north shore of Dalian Dayao Bay is studied to testify the feasibility and practicality of the new configuration of the Fuzzy Analytic Hierarchy Process and the optimal solution of the selection model.
