Self-adaptive report arrangement method for fault tree

Abstract

The invention discloses a fault tree-oriented report adaptive arrangement method, which comprises the following steps of: 1, importing a drawn fault tree, and defining or selecting a paper size for generating a fault tree report; 2, reading structure parameter information of the fault tree structure, and determining a scaling parameter r of the fault tree structure in a report from top to bottom; 3, for the fault tree structure exceeding the arrangement area, determining a transfer gate in the fault tree report, and decomposing the fault tree structure; 4, taking the branch where the transfer gate is located as a new fault tree to be arranged on a new page; 5, adding a hyperlink between the transfer gates; and step 6, generating a fault tree report according to the fault tree report format. The fault tree export report has the characteristics of reasonable layout, high readability and the like.

Description

technical field [0001] The invention belongs to the fields of safety engineering and reliability engineering, and relates to a fault tree-oriented report adaptive arrangement method. Background technique [0002] Fault tree analysis is a commonly used graphical analysis method, which is widely used in the fields of safety engineering and reliability engineering. Corresponding improvement measures to enhance the system design. [0003] In the process of fault tree analysis, highly complex safety-critical systems often mean that the scale of the fault tree that needs to be drawn in the analysis tool is huge, which brings great difficulties to export a fault tree report with high readability and standardized layout . At present, there is still a lack of unified understanding and standardized methods for the layout of fault tree export reports, and there is no unified specification for the layout process of logical gates such as AND gates, OR gates, and voting gates in the fau...

[0003] In the process of fault tree analysis, highly complex safety-critical systems often mean that the scale of the fault tree that needs to be drawn in the analysis tool is huge, which brings great difficulties to export a fault tree report with high readability and standardized layout

At present, there is still a lack of unified understanding and standardized methods for the layout of fault tree export reports, and there is no unified specification for the layout process of logical gates such as AND gates, OR gates, and voting gates in the fault tree structure and their branch nodes. This leads to problems such as uneven readability of reports generated by different fault tree analysis tools and unreasonable decomposition of fault tree structures.
