本文介绍了一种新的安全分析方法Hi-PHOPS（Hierarchically Performed Hazard Origin and Propagation Studies）。HiP-HOPS源于功能失效分析、失效模式与效应分析和故障树分析等经典技术。然而，它扩展，自动化和集成这些技术，以解决目前在复杂的安全评估中遇到的一些问题。该方法能够对复杂系统进行从功能级到低级别的组件故障模式的综合评估。它机械化和简化了大部分的分析，故障树的开发，并可以保证结果的一致性。HiP-HOPS目前由一个名为安全参数管理器（SAM）的工具支持。在本文中，我们介绍的方法，我们展示了它如何帮助我们分析和提高分布式制动系统的安全性的汽车。
This paper introduces a new method for safety analysis calledHi-PHOPS (Hierarchically Performed Hazard Origin and Propagation Studies). HiP-HOPS originates from a number of classical techniques such as Functional Failure Analysis, Failure Mode and Effects Analysis and Fault Tree Analysis. However, it extends, automates and integrates these techniques in order to address some of the problems currently encountered in complex safety assessments. The method enables integrated assessment of a complex system from the functional level through to the low level of component failure modes. It mechanises and simplifies a large part of the analysis, the development of fault trees, and can guarantee the consistency of results. HiP-HOPS is currently supported by a tool called the Safety Argument Manager (SAM). In this paper we introduce the method and we show how it has helped us analyse and improve the safety of a distributed brake-by-wire system for cars.
