如果单独研究人与人之间的关系及其活动,活动是人类学家和社会学家的事;如果单独研究机器,那是工程学家的事。在可靠性工程学中,需要研究人与机器如何能够最佳配合,使操作者能够快速、准确无误地操作设备,使设备可靠地发挥其功能。 If you study the relationship between people and their activities separately, the activities are anthropologists and sociologists; it is the engineer's job to study the machines alone. In reliability engineering, there is a need to study how people and machines work best together so that the operator can operate the equipment quickly and accurately, allowing the device to function reliably.
