Visio故障树图并行转换方法研究及实现

The Research and Implementation of Visio Fault Tree Diagram Parallel Conversion Method

为使不同人员建立的故障树图能够互相交流使用,并简化故障树分析软件的开发,降低开发成本,提高软件质量,对故障树图结构进行了分析,提出转换后用于表示故障树的格式。同时对VDX文件结构进行研究,提出了将VDX文件转换为上述格式的中间格式及转换算法,进而对其并行化以提高执行效率,给出了并行前后的耗时对比及提升倍率。另外再通过两个转换方法说明这种格式与目前较常用的故障树分析方法之间衔接的方式,并给出了算法流程。

For the fault tree diagram established by different people can be able to using and communicate with each other, and simplify the development of the fault tree analysis software, reduce development costs, and improve software quality, analysed the structure of the fault tree diagram, proposed the format which used to indicate the fault tree after the conversion. Simultaneously researched the file structure of VDX, proposed the intermediate format and the conversion algorithms which converts the VDX file to the format of above, and then took them parallelization in order to improve the efficiency, given the time-consuming and the rate of enhanced which compared before and after the parallel. In additional, via two conversion method to illustrate the convergence between this format and the commonly used fault tree analysis method, also given the algorithm processes.
