改进的动态故障树分析

Advancing Dynamic Fault Tree Analysis

Matthias Volk, Sebastian Junges, Joost-Pieter Katoen

摘要:

本文提出了一种新的状态空间生成方法的动态故障树(DFTs),以及一种技术来合成故障率的DFTs。我们的状态空间生成技术积极利用DFT结构-检测对称性,虚假的非确定性,并不关心。基准测试表明,在状态空间生成和分析时间方面的增益超过两个数量级。我们的方法支持DFT与象征性的故障率,并辅以参数合成。这使得能够确定系统组件的最大可容忍故障率,同时确保平均故障时间保持在阈值以下。

英文摘要:

This paper presents a new state space generation approach for dynamic fault trees (DFTs) together with a technique to synthesise failures rates in DFTs. Our state space generation technique aggressively exploits the DFT structure --- detecting symmetries, spurious non-determinism, and don't cares. Benchmarks show a gain of more than two orders of magnitude in terms of state space generation and analysis time. Our approach supports DFTs with symbolic failure rates and is complemented by parameter synthesis. This enables determining the maximal tolerable failure rate of a system component while ensuring that the mean time of failure stays below a threshold.
