Risk assessment system

Abstract

The invention discloses a risk assessment system, which comprises a risk assessment factor information acquisition subsystem, an expert judgment input module, a possibility and severity quantification subsystem and a risk display subsystem. The risk assessment system quantifies the possibility and severity of a risk source to obtain possibility and severity quantification parameters, takes the possibility and severity quantification parameters as an absolute coordinate of a possibility-severity coordinate system, and defines the risk area of the possibility-severity coordinate system, thereby overcoming the discrete problem, and strictly defining the risk value.

Description

technical field [0001] The invention relates to a data processing system, in particular to a risk evaluation system. Background technique [0002] With the rapid development of the world's civil aviation industry, the complexity and risk of aviation operations are increasing, which requires a more advanced risk management system, which can provide means for aviation operations to reduce risks, so as to move the safety gate forward , to achieve sustainable development of the civil aviation industry. [0003] The air traffic management industry occupies an important position in civil aviation operations and is an important guarantee department for aviation safety. Therefore, the risk management of air traffic control operation has become an important part of aviation operation safety. [0004] International Civil Aviation Organization (ICAO) in 2005 on the basis of mature experience in Europe and the United States, requires the contracting states to carry out the research an...
