中文摘要：

为降低具有人机合作特点的码头库场装卸作业事故发生率,提出一种考虑员工行为安全的作业流程设计方法。首先,分析作业人员的不安全行为,综合模糊事故树和贝叶斯网络分析作业流程的安全性,提出分析不安全行为产生原因的方法;然后,建立以作业事故发生概率最小化为目标,并满足时间约束的作业流程优化设计数学模型;最后,以北方某港口散货码头的钢板装卸作业为实例进行分析。结果表明：在仅考虑抑制7项主要不安全行为的条件下,用该方法可降低顶上事件发生概率约30%。

英文摘要：

A method of designing operation process was worked out for improving safety in material handling operation at seaports with consideration of human ’ s unsafe behaviors. Unsafe behaviors of operators were analyzed with the fuzzy fault tree method and the Bayesian network method to identify the reasons for the unsafe behaviors. A mathematical model,aiming at minimizing the probability of accidents and satisfying the working time constraint condition,was built for optimizing design of operation process.After this,an actual case based on the operation on a port in northern China was illustrated. The results show that the method can enhance the process safety by reducing about 30% occurrence probability of the top event under the condition that just top 7 unsafe behaviors were considered.
