The holistic modelling of operating complex systems with bounded dissi
pation capacity and high safety level requirements is discussed. Addit
ionally, damage measures are introduced which describe fault character
istics including damage evolution. Such a model allows, for example, s
imulation of the life cycle, and consequently it permits trend predict
ions to be made For safety monitoring and for damage evolution. The ho
listic methodology is demonstrated on a steel chimney and an offshore
platform with simulated measurements.
