Brochure

The current development in ageing prediction follows two directions, the deterministic and the stochastic approaches. This results in formulating an ageing model to describe the structural behaviour in the future.

A big issue is to involve investments in the models which put the structure in a better condition – this is the traditional renewal theory – and to find an optimal strategy for the owners or users in this way.

The Mini Symposium will focus on models in that field applicable for stakeholders and giving them the opportunity to deal with different maintenance policies considering aspects like penalty payments and traffic guidance costs.
