Agile Model-Based Systems Engineering Cookbook

By: Dr. Bruce Powel Douglass

Overview of this book

Agile MBSE can help organizations manage constant change and uncertainty while continuously ensuring system correctness and meeting customers’ needs. But deploying it isn’t easy. Agile Model-Based Systems Engineering Cookbook is a little different from other MBSE books out there. This book focuses on workflows – or recipes, as the author calls them – that will help MBSE practitioners and team leaders address practical situations that are part of deploying MBSE as part of an agile development process across the enterprise. Written by Dr. Bruce Powel Douglass, a world-renowned expert in MBSE, this book will take you through important systems engineering workflows and show you how they can be performed effectively with an agile and model-based approach. You’ll start with the key concepts of agile methods for systems engineering, but we won’t linger on the theory for too long. Each of the recipes will take you through initiating a project, defining stakeholder needs, defining and analyzing system requirements, designing system architecture, performing model-based engineering trade studies, all the way to handling systems specifications off to downstream engineering. By the end of this MBSE book, you’ll have learned how to implement critical systems engineering workflows and create verifiably correct systems engineering models.

Model simulation

When we test an aircraft design, one way is to build the aircraft and see if it falls out of the sky. In this section, I'm not referring to testing the final resulting system. Rather, I mean verifying the model of the system before detailed design, implementation, and manufacturing. SysML has some expressive views for representing and capturing structure and behavior and the Rhapsody SysML tool has some powerful features to execute and debug models as well as visualize and control that execution. There are other tools with similar capabilities. Notably, the Cameo Magic Draw Simulation Toolkit provides execution means almost as powerful as Rhapsody.

The Rhapsody modeling tool performs simulation by generating software source code from the model in well-defined ways and automatically compiling and executing that code. Rhapsody can instrument this code to interact with Rhapsody itself so that the tool can visualize the model execution graphically and provide...
