集裝箱碼頭雙40英尺岸橋優(yōu)化配置研究
[Abstract]:Affected by the development of global economic integration, container business in coastal ports shows a trend of rapid growth. The container ship Maersk Macker-Keni Muller has been put into operation on the Asian-European route. Declare world container transportation enters 18000TEU era formally. In order to adapt to the trend of ship size, some large container port areas in China, such as Yangshan Port of Shanghai Port, began to introduce double 40-foot quayside bridges for loading and unloading operations at the front of the wharf. The loading and unloading operation of double 40-foot shore bridge can shorten the ship's time in port, reduce the operating cost of the ship and enhance the comprehensive competitiveness of the port. However, the loading and unloading technology of the double-40-foot bank bridge is different from that of the ordinary shore bridge. If the port wants to give full play to the advantage of loading and unloading efficiency of the double 40-foot bank bridge, it needs to follow up the supporting equipment of the double-40-foot bank bridge simultaneously with its personnel and maintenance. Therefore, at present, most container ports with double 40-foot shore bridges are used for loading and unloading operations at the same time, which makes the ports keep the competitiveness of loading and unloading super-large ships at the same time. Terminal operating costs can still be within a reasonable range. In present container port, the application of double 40-foot shore bridge in loading and unloading is based on experience, which is lack of scientific and reasonable method. The purpose of this paper is to solve this problem. On the basis of summing up the loading and unloading technology of double 40-foot container terminal, this paper systematically analyzes the terminal operation cost and the ship's cost in port during the operation of the container terminal equipped with double 40-foot bank bridge. With the aim of minimizing the total cost of terminal operation in the whole process of port loading and unloading ship operation, the optimization model of double 40-foot quayside bridge configuration for container terminal is established from the point of view of macro control. In order to obtain the average number of ships in port, the berth utilization ratio of double 40 feet berth, the berth utilization ratio of common berth and so on, this paper is based on queuing theory, Markov theory, and so on. Considering the advantage of loading and unloading efficiency of double 40-foot berth, ships prefer to choose double-40-foot berth. A queue model of container terminal with different capacity is established, which can reflect the "double 40 foot berth" and "ordinary berth" of container port. The steady-state distribution of the model and the characteristic index of the queueing system are obtained by applying the theory of quasi-birth and death process. Finally, taking a container berth group arranged continuously in the north as an example, the correctness of the queuing model of container terminal with different berths passing through the container terminal is verified. The optimal total operation cost of the berth group wharf is calculated. The results show that when the double 40-foot berth of the container berth group and the common berth are (0 ~ 5), (~ 1 ~ 4), (~ (3), (~ (3), (~ (2), (~ (4) ~ (-1) and (5 ~ 0) respectively, the sum of terminal operating cost and ship's cost in port is the minimum when the berth group is equipped with a double 40 foot bank bridge and a common shore bridge are (035), (628), (1021), (1515 / 14), (207) and (25 ~ 0) respectively. In addition, the sensitivity analysis of the two parameters, the average number of ships arriving at port and the efficiency of the double 40 foot shore bridge abutment, is carried out in this paper.
