摘要: 为使自动生成的故障树图满足树图美学标准的要求,基于一般树形结构原则与树图美学定律原则,开发一种自动生成故障树绘制布局的算法。采用初始坐标、修改坐标和最终坐标表征树节点的位置关系,通过初始坐标完成兄弟节点间的相对布局,通过后序遍历形成的修改坐标完成节点之间的重叠规避。结果表明:绘制出的故障树图有视觉效果良好、空间利用率高以及能够满足友好的用户交互需求等优点,为故障树进行风险评价与可靠性分析提供有效的图形可视化与数据交互解决方案。

Abstract: For the purpose of making the automatically generated fault tree-diagram to meet the requirements of tree-diagram aesthetics standards, an algorithm was worked out for automatically generating fault tree drawing layout on the basis of general tree structure principle and tree aesthetic law principle. Initial coordinates, modified coordinates and final coordinates were used to represent the positions of the tree nodes. The relative layout between the sibling nodes was done by the initial coordinates and the overlap circumvention between the nodes was completed by the post-traveled formed modified coordinates. As a consequence, it is showed that the drawn fault tree-diagram has advantages of good visual effects, high space utilization, and friendly user interaction, providing valid diagram visualization and data interaction solutions for risk assessment and reliability analysis of fault trees.

Key words: fault tree, tree diagram, layout algorithm, risk assessment, reliability analysis
