4. Comprehensive assessment method and analysis technology for guarantee capability
The comprehensive evaluation methods are very diverse, and different evaluation methods have different characteristics and certain applicability, so that from some aspects, a certain comprehensive evaluation method is better than other evaluation methods, and a certain evaluation method is certainly suitable for evaluating a certain problem, and the key is to select an evaluation method suitable for the characteristics of an object to be evaluated. Most of the commonly used multi-index comprehensive evaluation methods are multi-scheme or transverse static sorting evaluation methods, which are more suitable for multi-decision evaluation, but are not used for evaluation of ground protection capability. From the evaluation result of the airport ground guarantee capability, the ground guarantee capability evaluation mainly judges which level state the ground guarantee capability belongs to, and the evaluation result is a comprehensive evaluation value.
The airport ground guarantee service has a hierarchical relationship, the ground guarantee service is composed of a plurality of sub-services, the assessment of the airport ground guarantee capability is decomposed layer by layer, and a reasonable and fair assessment conclusion can be obtained only by looking at the subsystem at the bottommost layer of the airport ground guarantee service, namely looking at each side surface representing the ground guarantee capability and integrating the information provided by each subsystem about ground guarantee operation.
Generally, one index is selected to be weighted, namely an evaluation principle is followed, the obtained weights reflect certain performance (or property), the evaluation principle is implemented into an evaluation conclusion through the fusion of index information and weight information, and in the evaluation process, in consideration of the advantages close to the essential meaning of index integration and easy explanation, for multi-index evaluation, a linear weighting integration method, which is an aggregation mode based on index performance, is preferably selected.
Linear weighted synthesis, also known as weighted arithmetic mean (WAA) operator or "additive" (SAW) synthesis, refers to the use of a linear model:
to perform comprehensive evaluation.
In the formula:
y: expressed as a comprehensive evaluation value of an evaluated object (system);
wj: index of evaluation xjThe weight coefficient of (a) is,
the multi-level evaluation model based on state classification has the following characteristics:
(1) the contribution of the weight coefficients can be attenuated in general but can be highlighted locally.
(2) The dangerous tendency of the system to develop towards the direction of 'deformity' caused by over-emphasizing the action of certain (or a certain) index weight coefficient is avoided.
(3) The method can play a positive role in promoting the coordinated development of the system objectively.
(4) Not only pays attention to the overall benefit of the ground protection system, but also highlights the local benefit of the ground protection system.
(5) Starting from the lowest subsystem, the 'information' provided by each subsystem about ground guarantee operation is integrated.
5. Facility equipment fault and damage mode type and grade judging system
Because airport facility equipment systems are various and complex in types, and the diagnosis of the fault and damage modes has special characteristics and uncertainty, a fault diagnosis expert system based on a fault tree method is developed aiming at the structural characteristics of the airport facility equipment so as to solve the problems of rapid detection, fault positioning and timely maintenance.
(1) And establishing a fault tree according to the logical relationship between the system composition, the function and the fault of the facility equipment.
The node branch number is divided into seven types: the logical relationship of single branch (binary tree) and the logical relationship of multiple branches (multi-branch tree), the reasoning relationship between the layers of the former is the logical relationship of 'OK' or 'NO'; the latter is characterized by the inference of multiple branches occurring in parallel.
The fault diagnosis flow chart of the single branch logical relationship is shown in fig. 5.
(2) Transformation of fault trees
For the case of multiple branches, the diagnostic reasoning for the actual fault may be branch by branch, so that multiple branches may be converted into a single branch logical relationship, see fig. 6.
The purpose of fault tree transformation is primarily to facilitate the storage of fault tree knowledge in a database.
(3) Expert database
The basic functions of a database are provided by a database engine, which is a software system that manages the storage and retrieval of data.
The decomposed result in the fault tree flow chart is stored in a database, corresponding to one record in a database table, the whole fault tree reasoning flow chart corresponds to one table in the database, and fields and data types in the table structure are determined according to software programming and the content required by experts.
According to the concrete situation of actual fault diagnosis, the method also comprises a monitoring point real object position diagram, a fault belonging principle diagram or structure diagram, picture annotation and the starting and ending time of a video file of a detection method. Because there are many fault diagnosis flow charts of the equipment, and the names of the flow charts are different, a name table containing the flow charts is added after the designed flow chart corresponding table, and the logical relationship is shown in fig. 7. Therefore, a database with rich content and perfect functions can be formed according to the flow chart and the newly added related data.
6. Facility equipment operation management optimization technology based on flight area operation flow simulation;
the operation flow of the flight area comprises the following steps: the approach process that the airplane enters an airport terminal area, lands on a runway through an approach route and finally slides to a stand is started; and the departure process that the airplane starts from a parking position, slides through the ground, arrives at the runway head, aims at the runway, takes off and finally flies away from the airport terminal area along the departure flight line. There are many factors that affect the operation of the flight zone, such as: the control system comprises a control tower, an airspace structure of a terminal area, ground guarantee, the number and the layout of runways, the number and the layout of parking positions, the proportion of take-off and landing aircrafts and the like.
The airport facility condition statistics can not provide a powerful and accurate support for guaranteeing the emergency wartime aircraft to carry out combat missions. And facilities related to the taking-off and landing of the airplane are numerous. The system comprises warehouses such as an oil depot, a military mechanical depot and a aviation material depot, command and communication facilities such as an underground command post, a tower, a flight control room and a weather station, aircraft maintenance facilities such as an aircraft maintenance plant, a fixed inspection plant, a four-station and a target range, and the like, wherein the states of a plurality of facilities are closely related to the taking-off and landing of the aircraft, whether the aircraft range can take off and land to fight a plane is directly determined if a barrier net exists, and whether equipment such as the fixed inspection plant and the target range exists or not has great relation to the taking-off and landing guarantee work of the aircraft in an emergency wartime environment.
(1) Optimizing an objective
The ground support service delay is one of the reasons for flight mission delay and has certain spreading. Therefore, the ground support aims to reasonably distribute the resource allocation of ground support facility equipment, avoid the delay of flight tasks caused by ground support and reduce the delay time. Meanwhile, from the maximum utilization efficiency of the ground support facility equipment, the ground support working capacity needs to be balanced, and the ground support facility equipment is effectively utilized.
The optimization objective function may be:
min∑ι,j∈Α(Ni-Nj) Minimum load difference of ground safeguard facilities and equipment
Wherein:
Tdi: representing the delay time of the ith flight due to ground support;
sign(Tdi) Is a symbolic function, which is expressed as:
Ni、Nj: respectively represents the number of flights guaranteed by the ground support vehicle i and the ground support vehicle j, and Ni>Nj。
(2) Simulation optimization
The ground guarantee is optimized by combining a BIM + GIS simulation platform, a simulation optimization process (shown in a flow chart in figure 8) is carried out, the ground guarantee configuration which most meets the target at present is selected on the basis of the current condition, and high and low dynamic allocation of facility equipment of each station along with the flight task amount is coordinated in the process that the flight task amount is from low to high and then from high to low, so that the method has important significance for improving the ground guarantee capability of the airport.

The map display module:the map display module is mainly implemented based on OpenLayers 3. The situation display system is a two-dimensional map display and comprises linkage of map zooming and translation and linkage of situation display.
The situation data processing module: the data processing module comprises data acquisition and data conversion. The method mainly researches how to acquire data from other data sources and convert the data into data required by a situation display module. The research of the situation data processing module comprises three steps:
firstly, defining an intermediate data structure required by a situation display module;
secondly, researching how to read all data from a data source and converting the data into an intermediate data structure;
and thirdly, researching how to acquire data from a data source in real time and push the data to the client in real time. This is done primarily by the server, since it involves reading directly from the data source.

Component system: the component framework is a programming framework constructed for the purpose of facilitating writing and using components. The component system provides a complete set of methods to write and invoke components. Since HTML is originally intended only as a platform for rendering designed for web pages, not an application development platform like desktop language, no component system is originally provided. If the native JavaScript is used for constructing an interface capable of interacting, the DOM needs to be operated frequently, and the logic of the component and the application logic are mutually crossed, so that the code is difficult to write and maintain.
It is significant to introduce component systems into web pages. First, the component system can support the componentization of some commonly used controls, components can be reused, and components can be dynamically introduced when needed. Secondly, each component is represented as an instance in JavaScript, and the operation of the component is packaged in the instance, so that the user can conveniently control the component in the script. In addition, the component system separates the definition of the components from the use of the components, reduces the coupling of the system and improves the maintainability.
The assembly system is composed of an assembly frame and various assemblies. Wherein each component is composed of a component logic and a component template. The component template is the content that needs to be inserted into the original webpage when the component is instantiated. The component template is placed in an external file. Component logic is the components created by the component framework.
The component framework is to encapsulate the component template and the component definition function by the above logic to form a new component constructor. The user can insert the component by calling the component constructor.
When a user invokes a component constructor, the component constructor does several things:
obtaining a component template from a corresponding file by using an AJAX technology, and inserting the component template into a place specified by a user;
calling a definition function of the component to initialize the component, and simultaneously obtaining a user-defined operation interface of the component;
and returning to the custom operation interface of the component. These interfaces are written to the component template.
