Data Dependency Network Analysis in SoS

This paper discusses the challenge messy data presents to System-of-Systems (SoS) performance, and introduces a technique for evaluating its effects. The technique, called Data Dependency Network Analysis (DDNA), based on previous work on Functional Dependency Network Analysis (FDNA), introduces a quantitative model for evaluating the effects of messy data in SoS and coming up with mitigation strategies. The paper also describes the DDNA implementation in an agent-based model and discusses its practical use in SoS engineering.
