Civil aviation:
Refers to the use of aircraft to engage in aviation activities other than national defense, police and customs. Civil aviation activities are a part of aviation activities. At the same time, its boundary with aviation manufacturing industry is defined by "using" aircraft, and it is distinguished from military aviation and aviation activities of other countries by "non-military nature".
Tourism and transportation:
Tourism transportation industry is a collection of various means of transportation, means and services to realize the spatial flow of tourists. In particular, tourism transportation should meet the needs of tourists in terms of safety, convenience, speed, comfort and low price, which requires the tourism transportation industry not only to have the function of general transportation, but also to meet people's tourism needs, and to form the characteristics of tourism transportation industry in terms of transportation tools, modes of transportation and service characteristics.
On-time flight departure rate:
"punctuality rate, also known as punctuality rate and normal flight rate, refers to the ratio of the number of flights (that is, normal flights) that are more consistent with the planned departure time when the air passenger transport department executes the transportation plan, representing the transportation efficiency and quality of the carrier."
Flight landing rate:
Flight landing rate is defined as the number of planes that land safely at the airport every hour.

The general idea and development strategy of the integrated development strategy of transportation and tourism in Henan Province/A/536738027 _120109837
Reason 1: Affected by the current epidemic situation, people's willingness to travel has generally decreased. At this time, the attendance rate was greatly reduced, and the ticket price began to be greatly discounted.
Reason 2: Off-peak travel affects air ticket prices.
Reason 3: grounding gas does not mean that there is no cost. The cost here is mainly reflected in the aircraft rental fee, airport parking fee, aircraft depreciation and maintenance fee, which are fixed expenses. When the plane takes off, although there are expenses such as take-off and landing fees, fuel fees, crew fees, etc., in recent years, civil aviation has begun to adopt subsidy policies for reducing fees, such as preferential fuel and take-off and landing fees. In this case, if you fly at a low price, at least part of the cost can be offset.
Reason 4: grounding will affect the use of global flight time resources.
Reason 5: At present, cheap air tickets are basically sold. Because low-cost airlines generally choose to land at airports with lower operating costs, sometimes they do not provide free meals and other additional services, so the overall cost is relatively low.
Reason 6: besides passenger transportation, flights also include freight and postal transportation. Under the current situation, land transportation is inconvenient. In order to ensure the mobilization of materials all over the country, air transportation has become the first choice.
Reason 7: In response to the call to resume work and production, there must be certain flight support.

Function: DEA (data envelopment analysis) is a method of operational research, which studies the economic production boundary. This method is generally used to measure the production efficiency of some decision-making departments.
Objective: The airport is a decision-making unit (DMU).
Model: CCR (derivative comprehensive efficiency = scale+pure technology) and BCC (derivative technical efficiency)
Input index matrix: terminal area, runway length, number of stands and number of runways.
Output index matrix: freight volume, passenger volume and navigable cities.
Objective function: efficiency evaluation index = output synthesis/input synthesis.
Constraint: 0
Fractional programming model->; Linear programming model->; Dual problem (solving min->; Seek max)
The relationship between the value of scale return and 1.
Relaxation variables: strong efficiency and weak efficiency.

Summary: The low cost of demolition and the low overlapping rate of airspace have led to the weak development of the northern part of the Yangtze River Delta.
Data come from meteorological airport report, TAF airport forecast and special weather report.
Among them, METAR and SPECI publish actual meteorological information, while TAF newspaper expresses future forecast information.

In addition to the traditional airport production statistics system (airport take-off and landing statistics, airport business statistics, airport throughput analysis (branches), passenger flow statistics and other reports), big data technology can also be applied to airport operation management such as airport strategic planning, route layout and planning, passenger composition, flight safety, flight normal rate, airport construction scale and investment scale. By analyzing the historical data of airport business reports such as production and flow direction and the actual operation of the airport, we can predict the medium and long-term aviation business volume of the airport, thus providing reliable data support for airport planning and route planning.
In addition, big data can also be applied to airport new route development and route layout planning. ......

TDS-delay step size distribution and delay time series, we can see that there is a regular effective delay step size distribution between the delay time series of two airports, which shows that there is a long-term stable correlation between the two airports.
