Using the critical path method in analyzing the interdependencies of critical services - Feasibility study

Abstract

Everyday life is more and more dependent on critical services and no one can argue that interruptions in transportation, electricity, etc. cause big problems in everyday lives. The interdependencies inside of certain sector services are growing, for example financial services are interrupted in losing internet banking system. Also, the interdependencies between critical infrastructure (CI) services are growing - in case of the power failure, the financial services are not usable etc. The aim of this paper is to propose another approach to describe the interdependencies between critical services. There is a lot of research done in analyzing and modelling the interdependencies between critical services, for example a survey performed by Idaho National Lab under the sponsorship of U.S. Technical Support Working Group identified 30 tools for critical infrastructure interdependency modeling [1]. Our research is adding some specialties in modelling CI interdependencies. © 2014 Springer International Publishing Switzerland.
