讲座简介：

1)  Value of Information in Structural Health Monitoring

Bayesian decision analysis in civil engineering was introduced by Benjamin and Cornell already in 1960 and has since played an important role for the optimization of design and management of safety, risk and reliability of structures and infrastructure systems. One particular variant of decision analysis, namely the pre-posterior decision analysis has however, despite its strong potentials in engineering decision making, been largely overseen. The present lecture provides first a basic presentation of the prior, posterior and pre-posterior decision analysis and thereafter elaborates on the use of the pre-posterior decision analysis in the context of Structural Health Monitoring (SHM). It is shown that the pre-posterior decision analysis – in the form of Value of Information analysis - provides a consistent and powerful means for assessing the benefits of SHM strategies even before they are implemented.  

2)  On the Regulation of Life Safety Risks

Life safety management is a key component in sustainable societal developments. In civil and not least in structural engineering, life safety management has been a focal point of research and development efforts for more than half a century – and methods of structural reliability have evolved to facilitate this with great success. In the present lecture the philosophy and rationale for managing life safety risks is presented. Taking basis in the marginal lifesaving costs principle from health economics it is shown how the Life Quality Index (LQI) may be applied to quantitatively assess whether engineering decisions with impacts on life safety are coherent with societal preferences for investments into life safety and also whether they are affordable. Moreover, it is shown how the LQI principle facilitates assessment of risks according to the ALARP principle and how it is utilized for setting target reliabilities for structures in design codes. Finally, the issue of how requirements to life safety risks should be understood in the context of regulations, standards and codes is addressed, with a special focus on temporal and spatial variability in life safety risks in the built environment.        

3)  Probabilistic Systems Characteristics - Robustness, Resilience and Sustainability.

The pressures on the Earth system originating from human activities are manifold, tremendous and vividly apparent. Both at the political and academic agendas sustainability of societal developments has become a top priority. At the same time there is an increasing demand for improved public welfare; calling for enhanced efficiency, reliability and resilience in all societal activities. It is evident that failure to achieve and maintain sustainable and resilient societal developments must be taken seriously at all levels of societal decision making. But how do we model resilience and sustainability such as to facilitate societal decision support?

The present lecture takes up this challenge and presents and discusses a framework for designing and managing resilience and sustainability of engineered systems.

Each of the lectures will have a duration of approximately 90 minutes followed by 10-15 minutes for questions and discussions.
