摘要
本文在事故系统模型化、逻辑结构简化的基础上,进一步探讨了逻辑结构优化的问题.对同样变量构成的事故系统,由于结构不同,其可靠性、安全性也不同,其中必有优劣之分.为了提高系统固有可靠性、安全性,必须调整结构,力争逼近其最佳值.为此,本文提出了"结构安全度"的概念,建立了结构优化的目标函数,计算了不同结构的结构安全度.可作为选择安全措施,制定最佳安全管理方案的理论基础.
On the basis of modellig accident system and simplifying logical structure, this article further explores the ways and means of optimizing logical structure In the accident system which is composed of same variables due to different structures the reliablity and security are different too.Therfore, in order to obtain high intrinsic reliablity and security in the system, we have to modify its structure so that its best value can be approximated, For this reason,this article summed up the conception in terms of'structure security',derivated the object function about structure optimization and caculated the structure security in the system containing different structurse, It can be used as the theiretical basis when we select safety measures or make the best structure security management scheme.
