Abstract

The capability to identify potential system hazards and operability problems, and to recommend appropriate mitigation mechanisms is vital to the development of safety critical embedded systems. Hazard and Operability (HAZOP) analysis which is mostly used to achieve these objectives is a complex and largely human-centred process, and increased tool support could reduce costs and improve quality. This work presents a framework and tool prototype that facilitates the early identification of potential system hazards from requirements and the reuse of previous experience for conducting HAZOP. The results from the preliminary evaluation of the tool suggest its potential viability for application in real industrial context.

从需求和面向重用的HAZOP分析中识别危害
识别潜在的系统危险和可操作性问题,并建议适当的缓解机制的能力对安全关键嵌入式系统的发展至关重要。危害和可操作性(HAZOP)分析主要用于实现这些目标,这是一个复杂且主要以人为中心的过程,增加工具支持可以降低成本并提高质量。这项工作提出了一个框架和工具原型,有助于从需求中早期识别潜在的系统危害,并重用以前进行HAZOP的经验。该工具的初步评估结果表明其在实际工业环境中应用的潜在可行性。
