Enterprise Architecture Dependency Analysis using Fault Trees and Bayesian Networks
2009 (English)In: Proc. 42nd Annual Simulation Symposium, 2009, 209-216 p.Conference paper (Refereed)
Analysis of dependencies between technical systems and business processes is an important part of the discipline of Enterprise Architecture (EA). However, EA models typically provide only visual and qualitative decision support. This paper shows how EA frameworks for dependency analysis can be extended into the realm of quantitative methods by use of the Fault Tree Analysis (FTA) and Bayesian networks (BN) techniques. Using DoDAF ? the Department of Defense Architecture Framework ? as an example, we provide a method for how these EA models can be adapted for use of FTA and BN. Furthermore, we use this method to perform dependency analysis and scenario evaluation on a sample DoDAF model.
