事件树

Besides protection maloperation model, this paper thought over other dependent outage models such as stuck breaker, component-group outage, station-originated outage and common cause outage; the article chose initial system state of cascading failure by using of function group decomposition technique and event tree analysis, provided simplification principle and processing method of continual fault process analysis, then proposed one new probabilistic risk assessment method for cascading failure.

The event-tree based modeling and optimization algorithms are adopted and the whole problem is divided into two sub problems (the portside sub problem and the refinery sub problem).Thus, the algorithm is proposed by analyzing the solving sequence of the two sub problems.

该方法把原油混输调度问题分解为码头调度子问题和厂区调度子问题，采用基于事件树的建模方法，并根据两个子问题的求解顺序提出了原油混输调度问题的分布式并行算法。

In the paper, the importance of FTA is described, the quantitative analysis method of the FTA is introduced in detail. Then the paper takes a vehicle control system as the research object, expatiates the forming of the CPU board fault tree, the establishing of the mean event fault tree and the obtaining of the mean event fault probability, and realizes the element level fault orientation on the CPU board of the vehicle control system. The test indicates that the method is both valid and correct.

文章在介绍故障树分析法重要性的基础上，较详细地介绍了FTA的定量分析法，并以某车辆控制系统为研究对象，从CPU板故障树的构建、各中间事件故障树的建立和各子事件故障概率等方面出发，实现了车辆控制系统CPU板元件级的故障定位，实验表明了该方法的有效性和正确性。
