摘要:

针对装备安全事故的突发性、复杂性,从系统安全熵“流程突变”角度构建灰色熵突变模型进行安全性崩溃分析。提出了复杂装备系统安全熵、安全熵函数、安全熵势函数等概念,刻画复杂装备系统安全状态从稳定到崩溃的演化机理和过程;建立了复杂装备系统安全熵函数的量子粒子群DGM(2,1)拟合模型,并以拟合值和实际值的灰关联度为适应度函数,提高模型拟合精度;构建装备系统安全熵尖点突变模型,给出安全性崩溃的灰色熵突变判据算法。最后,以某型飞机主起落架控制系统为例,验证了模型的有效性,为定量判断装备系统安全状态提供了新的方法。

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.
