提出了一种将成功可能性指数法（SLIM）与人误率预测技术（THERP）相结合的人误概率（HEP）评估方法。在这种方法中，SLIM已经被嵌入到THERP框架中，以在其不可用时生成标称HEP数据。所开发的方法被实施到海上凝析泵维修任务。在本研究的第一步中，考虑到所有标准工具和程序，估计了人为错误。在第二步中，作为附加措施，利用基于射频识别（RFID）的工具，并重新计算HEP。在不应用RFID工具的情况下，发现HEP值为5.7244 x 10（22）或估计为5.72%，不确定性界限为1.1448 x 10（-2）-1.1452 x 10（-1）。使用RFID工具，它减少到4.6342 x 10（-2）或4.63%，不确定性界限为2.145 x 10（-2）-2.089 x 10（-1），这产生了1.09%的净HEP减少。(C)2015化学工程师学会。Elsevier B.

The paper presents a novel approach for Human Error Probability (HEP) assessment by integrating the Success Likelihood Index Method (SLIM) with the Technique of Human Error Rate Prediction (THERP). In this approach, the SLIM has been embedded within the THERP framework to generate the nominal HEP data when it is unavailable. The developed methodology is implemented to an offshore condensate pump maintenance task. In the first step of this study, the human error was estimated considering all the standard tools and procedures which are in place. In the second step, as an additional measures, radio frequency identification (RFID) based tools are utilized and HEP is recalculated. Without the application of RFID tools, the HEP value is found to be 5.7244 x 10(22) or estimated as 5.72% with an uncertainty bound of 1.1448 x 10(-2)-1.1452 x 10(-1). With RFID tools, it is reduced to 4.6342 x 10(-2) or 4.63%, with an uncertainty bound of 2.145 x 10(-2)-2.089 x 10(-1) which yields a net HEP reduction of 1.09%.
