Abstract:

Due to suddenness and complexity of materiel safety accidents, a model of grey-entropy catastrophe is built to analyze safety collapse from the view of RhedogyMutation of system safety entropy. The concepts of safety entropy and safety entropy function and safety entropy potential function are proposed, disclosing the law and process of materiel safety states from stabilization to collapse. The fitting model based on quantum-behaved particle swarm optimization and grey system DGM(2,1) is constructed, and grey correlation analysis of the fitting value and the actual value is used as the fitness function to improve the model accuracy. A safety entropy cusp mutation model is established, and the criterion algorithm of materiel system safety collapse is designed. Finally， a case of the battleplan braking control system is provided to illustrate the availability of the model， which gives a new method for complicated materiel system safety judgement.
