MIMOSA Multi Non-Linear Structural Condition Modelling Simulation and Assessment Our entire infrastructure is aging. Assessment on its function is most important for their management. The traditional approach, namely visual inspections and subjective assessment, has not changed for a long time. On the other hand new knowledge from European research projects became available to VCE. This offers the opportunity to create an entirely new approach to modelling simulation and assessment of our infrastructure using sophisticated mathematical solutions and simulation routines.
