摘要： 提出操作流程图的概念，利用操作流程图来辨识人为差错。提供了操作流程图的3种基本模块，分析了如何建立操作流程图，给出利用操作流程图进行人为差错路径辨识算法，算法所得到的结果与事件树的结果是完全一致的。讨论了操作流程图针对事件树的优势及其发展趋势。

Abstract: A concept of Operation Process Diagram OPD) is presented and the means of how to identify human error using OPD is discussed. The three basic modules of OPD are illustrated. And, the means of OPD construction and human error identification are presented. The error identification results are identical to the results from even tree. The OPD’s advantage over event tree and further research are discussed.

Key words: human error, human error identification, event tree, Operation Process Diagram(OPD)
