The figure shows the sub-process “CH health analysis”, which is related to the material and structural health of the CH asset. These two characteristics contribute to the judgment on whether the threat is significant or not. However, poor CH asset’s health influences vulnerability and contributes to the exploitation of the vulnerability by threat. During the CH health analysis in situ diagnostic protocols and systematic protocols related to the diagnostic and analytical strategies (developed in WP3) stored in knowledge base are to be deployed.
