Embodiment Construction

[0070] Such as figure 1 and figure 2 An airport group efficiency and policy evaluation method based on system dynamics is shown, including the following steps:

[0071] Step 1: Establish a central server and a data center, and the data center communicates with the central server through the Internet; establish a causal relationship diagram module, a flow diagram building module and a simulation module on the central server;

[0072] Step 2: The data center collects and stores the airport group information. The airport group information includes the passenger flow information of all airports in the airport group, the airport passenger capacity information, and the international passenger proportion data used to quantitatively represent the international positioning of key airports. Quantitatively represent the feeder navigation point data for the secondary airport feeder positioning, the number of low-cost base airlines for the low-cost positioning of the secondary airport, a...

Abstract

The invention discloses an airport group efficiency and policy evaluation method based on system dynamics, which belongs to the field of aviation technology. Firstly, according to the dynamic changes of airport groups and the characteristics of mutual influence between airports, an airport group efficiency system flow based on system dynamics is established. Then, in the constructed model, adjust the variable parameters, study the impact of the policies adopted by the airport on the efficiency of the airport group, verify the feasibility of the policy, comprehensively analyze the characteristics of the airport group from the perspective of the system, and reveal the feedback mechanism and inner nature of the airport group. structure, constructing an airport group efficiency system flow diagram that is more consistent with the actual airport group, by adjusting variable parameters, simulating the airport policy, explaining the rationality of policy implementation more clearly, and being able to reflect the dynamic changes of the complex system of the airport group, the present invention can It is used to evaluate the new policy, and adjust the value of the variable by quantifying the policy variable to provide the most reasonable way to implement the policy.

Description

technical field [0001] The invention belongs to the field of aviation technology, in particular to an airport group efficiency and policy evaluation method based on system dynamics. Background technique [0002] An airport group is a collection of two or more airports that serve commercial air transport in an area and that influence each other. Through the complementary functions of the airports and the differentiation of market positioning, it is possible to avoid repeated investment and Vicious competition, effective use of limited social and economic resources. But at present, the division of labor of each airport in the airport group is not clear, and the positioning is repeated. Passengers gather at key airports, the supply of flights is in short supply, and the overflow is obvious, exceeding the capacity that the airport can guarantee, resulting in airport congestion and flight delays. However, other airports in the airport group have less transportation demand, the ...
