An Human Error Data Base for Chinese Aeronautical Facilities

Human error, which is a long-standing problem in the aeronautical system and other systems, has caused severe consequences. However, it was only in the nineteen eighties that the problem really attracted researchers' attention in the world; while in China, it attracted attention much later. The first question faced by researchers in human error is the question of human error data. The author has set up an unique human error data base (HEDB). The HEDB consists of seven sub-data bases, including six sub-data bases (according to the six ways of collecting data) and a model sub-base. The model sub-base appears to be unknown in the open literature. The author holds that it is the indispensable or the key part for setting up the HEDB. It contains the various prediction models of human error and environment, considers the correlation and multidimensions of the human factor, and can analyse different data sources with corresponding models immediately. Therefore the model sub-base has provided a powerful tool for getting rid of the constraint conditions of models in the base and thus for seeking an algorithm that can be used in general. The model sub-base also makes it convienient for us to compare the different ways of analyzing data.
