Interactive Model-Centric Systems Engineering (IMCSE) Phase Two

Abstract : Model based systems engineering (MBSE) is becoming increasingly more important in the practice of SE. To take advantage of model-based techniques, it is important to improve human and technology integration. The Interactive Model-Centric Systems Engineering (IMCSE) research program develops SE methods, processes and tools (MPT) to improve this interaction. The IMCSE research program aims to develop transformative results through enabling intense human-model interaction, to rapidly conceive of systems and interact with models in order to make rapid trades to decide on what is most effective given present knowledge and future uncertainties, as well as what is practical given resources and constraints. This project explores development between value choice-tradeoff, supportive MPTs, and interactive Epoch-Era Analysis (IEEA), a framework for narrative and computational scenarios. Exploration includes human interface and reasoning considerations for epoch, era characterizations, and multi-epoch/era analyses. Leveraging prior work from DARPA META, the Interactive Schedule Reduction Model (ISRM) was extended promoting sensitivity analyses and benchmarking to be the central use case. The IMCSE research program for Phase 2 extends the original set of objectives. The work accomplished includes: Pathfinder state fo the art-practice research gathered and published, further strategies and implementations for IEEA, and completion of ISRM web-based prototype.
