In reality, uncertainty is one of the basic attributes of various cascading, interactional or compound events related to CPI . Thus, accurately modeling the multi-hazard coupling effects is still a challenging work due to the involved high uncertainty. The uncertainties of hazard-formative factors, the hazard-formative environment, and hazard-affected objects can markedly change the system response, and thereby the safety of CPI system . In the presence of uncertainty, the most important consideration is integrity: an appropriate model should provide an accurate representation of observed knowledge about the coupling hazard-formative mechanism.
