Embodiment Construction

[0027] The human factor reliability assessment method of aviation maintenance based on Rough Set Theory (RST) and Interval Analytical Hierarchy Process (IAHP) includes the following steps:

[0028] 1) Establishment of human factor reliability evaluation system for aviation maintenance system:

[0029] Suppose R is a collection of indicators that affect the reliability of aviation maintenance subjects R = {r 1 ,r 2 ,...,r m}, where r i (i=1,2,...,m) are various indicators affecting the reliability of human factors in flight subjects, m is the total number of indicators, and the human factor reliability of aviation maintenance system is divided into: maintenance personnel quality, aircraft maintainability design level, job complexity, organization and management factors, the quality of maintenance personnel includes fatigue, psychological quality, technical proficiency, and cultural quality; the level of aircraft maintainability design includes the scientificity of the man-ma...

Abstract

The invention provides an RST / IAHP-based aeronautical maintenance human factor reliability assessment method. The method comprises the steps that firstly, a hierarchical aeronautical maintenance subject human factor reliability index assessment system is established through a decision tree method; secondly, a quantitative index weight based on a rough set discernable matrix is determined; finally, a quantitative index weight based on the interval analytic hierarchy process is determined. By means of the method, inaccurate and incomplete index data can be effectively processed, and the method is high in operability and applicable to specific human factor reliability assessments on different maintenance subjects.

Description

technical field [0001] The invention belongs to the field of aviation, in particular to an aviation maintenance human factor reliability evaluation method based on rough set theory (RST) and interval analytic hierarchy process (IAHP). Background technique [0002] With the continuous improvement of aircraft safety level, accidents caused by mechanical failures have been significantly reduced, and flight accidents caused by human errors are on the rise. Aviation maintenance is an important link in the aviation system, improving its human factor reliability and reducing maintenance errors are of great significance for ensuring the safety of the aviation system. Due to the basic characteristics of human errors in aviation maintenance, such as concealment, inevitability, accumulation and suddenness, the factors affecting human behavior are multifaceted, multi-level and intricate, making human behavior extremely plastic and difficult to control Quantitative analysis of aviation ...
