Characterizing the relevance, the level and the type of uncertainty can help a manager find the best ways to manage the potential consequences of aging on an infrastructure service level. In the presence of high uncertainty, the manager must have a formalized decision-making process to protect its global resources. The cost of the treatment and the potential consequences of risk associated with these resources constitute a "risk provision" liability. In order to communicate with financing agencies, this provision can be combined with the system's residual value to obtain a "heritage index". Finally, in order to follow the evolution of an infrastructure system, the manager can use the notion of turbulence that arises from combining the heritage index and the net present value of the maintenance plans. This turbulence index monitors the equilibrium between the economical efficiency of the action plans and the heritage sustainability. The control of this equilibrium and its uncertainty are two key elements for the sustainable development of our infrastructures. Source

The aim of structural monitoring is to get mechanical and valuable information concerning structural parameters. A generic frame was developed in order to identify unknown parameters thanks to an iterative process using a meta-heuristic algorithm. It combines data obtained through structural monitoring, a mechanical model and an optimization algorithm. The quality of identification depends on the quality of the data set, on that of the mechanical model and on the algorithm efficiency. It is shown through several tests on two case studies how uncertainty or errors arising from various sources can impact the accuracy of predicted values.© 2014 Elsevier Ltd. All rights reserved.
