Abstract
The technical infrastructures of the society are becoming more and more interconnected and in-terdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Distur-bances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important to take these interde-pendencies into account when assessing the vulnerability of technical infrastructures. In the present paper, an approach for modeling interdependent technical infrastructures is proposed. The modeling approach is based on aspects of network theory, but with additional functional models for each modeled system. By... (More)
The technical infrastructures of the society are becoming more and more interconnected and in-terdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Distur-bances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important to take these interde-pendencies into account when assessing the vulnerability of technical infrastructures. In the present paper, an approach for modeling interdependent technical infrastructures is proposed. The modeling approach is based on aspects of network theory, but with additional functional models for each modeled system. By modeling an electrified railway network, which consists of five system and dependencies between the systems, it is shown how the model can be employed in a vulnerability analysis. The model aims to capture both functional and geographic interdependencies. It is concluded that the model is suitable for vulnerability analyses of interde-pendent systems and the next step is to utilize the model in a full-scale vulnerability analysis. (Less)
