Problems solved by technology

According to the current situation of important flight dispatch work, these data are usually scattered in different system modules, which require a lot of manpower and time to inquire, and are prone to omissions; in addition, different personnel have different subjective judgment standards for aircraft technical conditions. Undesirable "manual error"

Embodiment 1

[0037] Embodiment 1 Quantitative Model of Aircraft Technical Conditions

[0038] The aircraft technical condition quantification model described in the present invention will be described in further detail below.

[0039] According to the experience of maintenance engineering, the general idea of ​​the quantitative model of aircraft technical status is as follows: 1. Recognize that the new aircraft has reached the design reliability level and is in a completely healthy state when it leaves the factory; 2. Design problems or faults and defects found during aircraft operation , and factors such as performance decline brought about by the aging of the aircraft will reduce the reliability level of the aircraft; 3. The implementation of regular maintenance card and related work can restore the reliability level of the aircraft.

[0040] Based on the above ideas, select the parameters related to the technical status of the aircraft, summarize their respective laws, and calculate the...

[0067] Embodiment 2 Construction of Quantitative Model of Aircraft Technical Conditions

[0068] The method for constructing an aircraft technical condition quantification model according to the present invention will be further described in detail below.

[0069] (1) Parameter selection research and analysis

[0070] There is no uniform standard in China's civil aviation industry for the evaluation of aircraft technical status, so it is necessary to conduct research on parameter selection and use scientific theoretical methods to determine the rationality and weight of parameters.

[0071] (1.1) Research form

[0072] according to figure 1 The parameter data structure shown, as well as the needs of subsequent theoretical analysis such as AHP and gray clustering, the research form formulated by this project is shown in the table below.

Abstract

The invention discloses a quantification model of technical conditions of an airplane and a construction method of the quantification model. Through a proper method, a quantification model of technical conditions of an airplane is constructed. The quantification model has a data structure in a certain level. The data structure comprises maintenance report data, engine performance data, reliability management data, engineering management data and common data. Each data comprises a data item. Each data item is defined into an event parameter or a risk parameter, and has a corresponding scoring logic and a scoring method. Each event parameter is divided into A, B, C, D and E grades according to the serious degree of the event. Each grad has a corresponding quantification score value. According to the invention, technical conditions of the airplane can be comprehensively and directly displayed; relative data is conveniently searched, exported and stored; and the model and the method are assistances for airplane dispatching decisions.

Description

technical field [0001] The invention relates to the field of aircraft maintenance reliability management, in particular to an aircraft technical status quantification model and a construction method thereof. Background technique [0002] Airlines often face the problem of assessing the technical status of aircraft when dispatching aircraft, especially for important flights such as special planes and VIPs. Usually, it is necessary to arrange the aircraft with the best technical status for execution. At present, when selecting aircraft for important flight dispatch, most domestic airlines use the method of relevant responsible units to provide aircraft technical status data to determine the status of the aircraft. This method is usually highly subjective, and the key data are relatively scattered, and the query is time-consuming and laborious. With the in-depth development of aviation maintenance reliability management, the reliability data collection system and analysis meth...
