直到最近，我们的社区才认识到结构健康监测（SHM）的好处可以使用信息价值（VoI）的概念进行适当的量化。VoI是在有和没有监测系统的情况下操作结构的效用之间的差异，通常称为前后效用和先验效用。在计算VoI时，一个普遍理解的假设是，所有关于系统安装和操作的决策都是由同一个理性主体做出的。在真实的世界中，决定购买监控系统的人（所有者）往往与实际使用监控系统的人（管理者）不是同一个人，即使两个人都是理性的，并且接触到相同的背景信息，他们也可能因为不同的风险厌恶而表现不同。我们提出了一个配方，以评估从所有者的角度来看，在经理与所有者不同的情况下，他们的风险优先级。此外，我们应用的结果在现实生活中的案例研究有关斯特里克桥，在美国普林斯顿大学校园的人行天桥。这个框架的目的是帮助业主量化的钱，通过委托的结构状态的监测系统的评估，即使管理者的行为对风险是不同的业主自己的，所以是他或她的管理决策。案例研究的结果证实了两种方法的差异，以量化的VoI的监测系统。
Only very recently our community has acknowledged that the benefit of Structural Health Monitoring (SHM) can be properly quantified using the concept of Value of Information (VoI). The VoI is the difference between the utilities of operating the structure with and without the monitoring system, usually referred to as preposterior utility and prior utility. In calculating the VoI, a commonly understood assumption is that all the decisions to concerning system installation and operation are taken by the same rational agent. In the real world, the individual who decides on buying a monitoring system (the owner) is often not the same individual (the manager) who will actually use it. Even if both agents are rational and exposed to the same background information, they may behave differently because of their different risk aversion. We propose a formulation to evaluate the VoI from the owner’s perspective, in the case where the manager differs from the owner with respect to their risk prioritisation. Moreover, we apply the results on a real-life case study concerning the Streicker Bridge, a pedestrian bridge on Princeton University campus, in USA. This framework aims to help the owner in quantifying the money saved by entrusting the evaluation of the state of the structure to the monitoring system, even if the manager’s behaviour toward risk is different from the owner’s own, and so are his or her management decisions. The results of the case study confirm the difference in the two ways to quantify the VoI of a monitoring system.
