人为因素方法依赖于理解人的能力和各种条件下的限制的性质，并将这些知识应用于设计和开发安全系统。遵循MTO （Man Technology Organisation）方法的原则，重点应放在人与技术和组织系统的互动方式上。建立了人工超声检测中人为因素对超声检测性能影响的模型，并对其中一部分进行了实证检验。实验任务包括在无、中、高时间压力下，按照标准程序重复检测18个缺陷。测量了压力应对策略、任务的心理工作量、压力反应和组织因素。结果表明，时间压力、心理负荷和经验对检验绩效的质量有影响。操作人员认为组织因素及其对检查结果的影响是重要的。然而，对压力的影响还需要进一步的研究。
The human factors approach relies on understanding the properties of human capability and limitations under various conditions and the application of that knowledge in designing and developing safe systems. Following the principles of the MTO (Man Technology Organisation) approach, emphasis should be given to the way people interact with technical as well as organisational systems.A model describing human factor influences in relation to the performance shaping factors and their effect on manual ultrasonic inspection performance had been built and a part of it empirically tested. The experimental task involved repeated inspection of 18 defects according to the standard procedure under no, middle and high time pressure. Stress coping strategies, the mental workload of the task, stress reaction and organisational factors have been measured. The results have shown that time pressure, mental workload and experience influence the quality of the inspection performance. Organisational factors and their influence on the inspection results were rated as important by the operators. However, further research is necessary into the effects of stress.
