On the utilization of multiple information for the integrity management of deteriorating systems

• Recent years’ publications have shown how valuable information can be in the integrity management of civil structures. Monitoring systems increase the knowledge about the structural state, improving the prioritization of the interventions, and the selection of optimal maintenance strategy and thereby allowing for budget optimization and risk minimization. This paper investigates the effect of multiple information on integrity management throughout a deteriorating structure’s life cycle. Pre-posterior analysis and the concept of the Value of Information (VoI) are used to quantify the benefit multiple information provide in structural integrity management. Multiple information (e.g., local information about the condition state of the several components of a system) and actions are associated with an expected utility. Optimization is performed by determining the lowest total expected cost of the maintenance strategy for a given set of information.
