某型导弹技术准备人因安全性分析

某型导弹技术准备过程具有涉及操作人员多,人员间以及人与设备之间交互多的特点,系统级的安全性分析结果表明,人为致因因素是导致安全问题的重要因素。因此,文章研究了一种基于行为模型的人因安全性分析方法(Extended STPA with Behaviour Model,BME-STPA)。BME-STPA方法基于行为模型思想,对 STPA控制器模型进行扩展,使其更加适用于人为致因因素分析,解决了 STPA方法对人因安全性分析针对性不强的问题,具有较强的可操作性。以导弹加注过程中溢出灌增压作为 BME-STPA的应用案例,证明了该方法的实用性和有效性。

Personnel Safety Analysis of the Preparing Technology of a Certain Type of Missile

A certain type of missile technology preparation process has many features. It involves many personnel, andmany interaction between personnel and equipments. The safety analysis results from system level shows that the humanfactors are important factors leading to security issues. Therefore, in this paper an extended STPA with Behavior Model,(BME-STPA) was invented. The BME-STPA method was based on the behavior model idea, and the STPA controller mod.el was extended to make it more suitable for the analysis of cause factor analysis. The problem that STPA was not targetedto human safety analysis and had very strong maneuverability. The application case of BME-STPA was presented in thispaper, which proved the practicability and effectiveness of this method.
