Application Of The Complex System Brittleness In Colliery Accident Modeling

Along with the development of society and the improvement in technology, systems become huger and huger, more and more complex. Therefore the study of complex system becomes the hot spot. Now the researchers consider that the basic characteristics of complex system include complexity , openness , non-linear , evolution, levels, largeness. Among a complex system, because the interference outside is indefinite and the system have innate defect inside, one of its subsystem may collapse when it is struck abruptly, then the whole system will be disordered and it collapses finally. According to this condition of complex system, the brittleness of complex system is derived.At first, I depict the definition of brittleness of complex system and embody the collapse of system. Secondly, I analyze the brittleness process of colliery system, I disport the process to inside process and outside process. Outside process include brittleness infection between colliery and some outside system, and these system include: some industry correlate to coal, coal market, government policy , economy and so on, Basis of the brittleness contact between them, I set up the outside brittleness process model; Inside brittleness process is mainly analyze the brittleness contact of some subsystems of colliery system, I define the inside brittleness degree, and using it I denote the hidden trouble of colliery system, and government policy control the accident by the brittleness degree.At last, regard the town colliery and national colliery as the example, in the instance of no disturb, I have the trend of inside brittleness degree, the compare of two colliery show the problems of the town colliery, and the problems are too small safety cost, too big inside hidden trouble. The accident is induced by the...
