Problems solved by technology

[0005] However, the shortcomings of the existing technology are: the dynamic changes of the airport group cannot be considered; the airport group system cannot be simulated to reveal its internal structure; the model parameters cannot be adjusted to evaluate the development policy of the airport group

Embodiment Construction

[0070] Such as figure 1 with 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, ...

Abstract

The invention discloses an airport cluster efficiency and policy evaluation method based on system dynamics, so that that invention belong to the field of aeronautical technology, At first, accord tothat dynamic changes of airport group, The nature of the interactions between airports, a system flow diagram of airport cluster efficiency based on system dynamics is established, and then in the constructed model, Adjust variable parameters, to study the impact of airport policies on the efficiency of airport clusters, Verification of policy feasibility, From a system perspective, Comprehensiveanalysis of airport cluster characteristics, revealing the feedback mechanism and internal structure of airport cluster, a flow chart of airport cluster efficiency system is constructed, which is in good agreement with the actual airport cluster, By adjusting variable parameters and simulating airport policy, the rationality of policy implementation is explained more clearly, and the dynamic change of complex system of airport cluster can be embodied. The invention can be used for evaluating new policy, and the most reasonable way of policy implementation can be provided by quantitatively adjusting policy variable and adjusting variable value.

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 ...
