Layout Optimization of Beijing-Tianjin-Hebei General Aviation Airport

General aviation is an important part of the national emergency rescue system, how to make rational layout of general aviation airports have great significance for improving China's overall aviation emergency rescue. The paper studied region general aviation airports layout optimization through the analysis of influencing factors on the Beijing-Tianjin-Hebei region general aviation airports layout. What's more, it used the calculation method of fire station response area to determine the general aviation airport emergency response time and service radius. Combining the population density, level of risk and economies of scale, this paper analyzed the scope of services of the airport of Beijing-Tianjin-Hebei and existing general aviation airports and optimized the layout, site selection and range of services in this area. Finally, the use of AHP helps determine the index weight of Beijing-Tianjin-Hebei region general aviation airports layout and ultimately determine the optimization program by the index evaluation. The study provides a reference for the city emergency rescue public infrastructure layout optimization.
