Port Berth Resources From The Perspective Of Port And Shipping Cooperation Opportunity Cost Measurement Method

With the continuous deepening of economic globalization,port and shipping cooperation has become an important development direction of international container shipping.More and more shipping companies are seeking vertical dimension cooperation with ports to increase their competitiveness.As the core resource of the port,the berth of the port is an important foundation for the establishment of cooperation between the port and the shipping parties.The measurement of its market value usually becomes the focus of dispute between the two sides.Therefore,how to use scientific and reasonable methods to evaluate the market value of dock berth resources in port and navigation cooperation is very important for port operators.However,until now,the special research on such problems has not been found.In order to solve the above problems,this paper studies the opportunity cost measurement method of wharf berth resources from the perspective of port and shipping cooperation,The main research contents of this thesis are as follows:(1)Explored the cooperation modes between container ports and shipping companies,and sorted out the differences between different cooperation modes such as berth leasing and berth use priority.Further,the paper summarizes the research results and theoretical concepts involved in the measurement of the market value of berth resources in container terminals,and puts forward the idea of estimating the opportunity cost of berth resources from the perspective of ports(2)Starting from the actual operation of container terminals,taking the operation system of container terminals as the research object,taking into account the impact of the shipping schedule density,ship type and number of berths on the operating income of container terminals as well as the complexity of revenue opportunity cost measurement,the integrated simulation problem considering the number of ships,ship type and number of berths is proposed.Aiming at the problem of integrated square array in this paper,the data of ship arrival at port are processed by statistical analysis,so as to make the data conform to a certain distribution law.Secondly,the opportunity cost model and the strategy simulation model are constructed by using the mixed linear programming method as the simulation rule model of data.Finally,the average expected value method is used to construct the data output model.(3)The Monte Carlo simulation framework includes berth-related arrangements,and the large neighborhood search algorithm is designed for berth-related arrangements in the simulation evaluation framework to solve the berth-optimization,and the data of specific example ports are input for Monte Carlo simulation,and the output data of simulation are processed to solve the opportunity cost under different cooperation strategies.The results of case analysis show that under the change of the basic parameter of shipment density,the difference of opportunity cost can change up to $1.01 million at the maximum and about $2000 at the minimum.The impact of the number of berths on the opportunity cost difference is between $1190 and $970,000.The variation of opportunity cost difference of container ship type is between $4,500 and $520,000,which fully proves the applicability and predictability of the simulation model in different market changes.The simulation framework developed in this paper is used to evaluate the opportunity cost of benefits of dynamic berths in the shipping market under port and shipping cooperation,and at the same time provides a pricing standard for the resources of terminals under the context of port and shipping cooperation,and provides a reference value for the maximum benefit utilization of ports and shipping enterprises in different markets.
