Graph Trace Analysis and generic algorithms for interdependent reconfigurable system design and control

This paper discusses current research for development of model-based generic algorithms for design and control of reconfigurable interdependent systems. This work is based on extension of Graph Trace Analysis (GTA), wbich was originally developed in the 1990s for power distribution system design. Because of GTA's ability to combine and restructure analysis methodologies from a variety of problem domains, it is now being used for integrated power distribution and transmission system design, operations, and control. Over the last few years research has begun to formalize GTA into a multidiscipline approach that uses generic algorithms and a common model-based analysis framework. The paper provides an overview of the concepts used in GTA, and then discusses bow GTA and generic algorithms can be used together for design and control of multidiscipline systems. This new approach includes decoupling component and system level equations, using iterators to structure iterative analysis that simplifies coordination of discrete events and also eliminates the need for large matrices, using composition to implement polymorphism and simplify data management, using dependency components to structure analysis across different systems types, and implementation of hot-swappable algorithms.
