Safety Management Efficiency Of Civil Aviation Industry In Large Time-Space Scale

Aviation safety is the basis of civil aviation development. The safety management of civil aviation industry has the industrial specialties of systematism, continuity, internationality and informationization. It is urgent to build a high-efficient safety management system keeping pace with the high-speed developing civil aviation industry in China. Guilding by scientific outlook on development and systematic safety thought, the dissertation makes exploring researches on how to develop the safety management system and improve the safety management efficiency under the new situation of China civil aviation industry. The main researches are as following:1. Both promotional and constraint functions to the development of civil aviation acted by aviation safety management is studied. From the view of aviation safety management in a large time-space scale, the inherent laws of civil aviation development with the national economic development and civil aviation safety with civil aviation development as well as the correlations between them were analyzied. Models and mechanisms for safety pressure formation and transmission are studied.2. The theory of safety management effiency in civil aviation industry is explored, including the meaning, transmission mechanisms and measure indices of safety management effiency of civil aviation, in order to correctly understand and quantitatively assess the safety management efficiency of civil aviation.3. The institutional foundation to improve safety management efficiency of civil aviation is studied. The basic attributes and functions of safety management system of civil aviation industry is analyzed, and the functional model of industrial safety management system ROSE is designed. Based on ROSE model, functions of governments and enterprises in safety management, 3 core subsystems and 4 environmental elements, dialectic relationships among the core subsystems and between the core subsystems and environmental elements are presented.4. The information foundation to improve safety management efficiency of civil aviation is studied. Focusing on risk assessment, the core of systematic safety management in civil air transportation industry, the attributes and changing patterns of risk in air transportation are explored, the theory of"two categories of risk"are put forward and a practical risk assessment system is designed based on the incomplete safety information. From the view of international safety information sharing, the comprehensive comparison of different laws and regulations, taxonomies and database structures of aviation safety information adopted by ICAO, the EU and China are given, and the prototype of aviation safety information sharing between the CAAC system and the ECCAIRS system used in the EU and in ICAO is developed, which implements a bi-directional exchange of information between the two systems. The mechanism of international safety information sharing is also studied.5. The key technical support to improve safety management efficiency of civil aviation is studied. At the enterprises level, it is one of the most important things to assure aviation safety. Using of the scientific tool can decrease the crew error and control the risk of flight operation. Flight Operation Quality Assuranse technology, management and their limitions are discussed, and a method of risk assessment of flight operations based on BP Neural Network is given.6. The development strategy of industrial safety management system is studied. Guilded by self-organization theory, the pratical experiences of the construction and development of industrial safety management system of international and China civil aviation are analyied. To keep the improvement of safety management efficiency as the central task, the development of industrial safety management system of China civil aviation is explored. The strategic meaning, main principles, implement strategy and key tasks are studied in order to explore the comprehensive and persistent approach to improve the industrial safety management effiency of China civil aviation.
