In Part 1 of this series, we introduced some ideas about Model-Based Systems Engineering (MBSE) approaches to the development of Autonomous Vehicles (AVs). Our specific interest in this series is the modeling of requirements in combination with functional architecture, software configuration repositories and project management. With Syndeia, the system engineer has two general approaches by

Of the many tool Syndeia connects, the Simulink interface has attracted some of the greatest interest. Intercax has just released a new video describing this interface for Syndeia 3.1. At seven minutes long, it provides an overview and demonstration of some of the use cases it supports in linking SysML (MagicDraw or IBM Rational Rhapsody)

Intercax introduced the Syndeia interface for Jama Software in May, 2017 and described it in multiple formats, including a blog post and white paper and a webinar. What has been missing is a concise overview to introduce new potential users to the interface features and use cases. We have added an 8-minute video as a resource

Autonomous vehicles (AVs) represent one of the greatest challenges yet to system engineering. Not only are AVs complex systems in their own right, they are potentially part of a larger connected infrastructure of smart roads. Model-based approaches, including SysML modeling, represent a game-changing opportunity to meet that challenge. In this blog series, we shall look

The V-model has long provided a metaphor for the classic systems engineering (SE) process, but it is problematic in the Model-Based Engineering (MBE) context: Figure 1 The Systems Engineering V-model It does not reflect much of the work systems engineers actually do. Of the six generic use cases we described in Part 1 of this

Most MBSE methodologies place emphasis on organizing the model correctly before actually modeling the system, but this task should not be approached too narrowly.  First, as we discussed in a previous blog, modeling should encompass both the system under development and the project structure, which includes both process and organization. Model organization should facilitate collaboration

Introduction Axe in hand, I strode into the misty forest, looking for the perfect Christmas tree. As the slushy snow soaked into my shoes, I thought, “I should have modeled this first!” In any project as critical as decorating the house for Christmas, Model-Based Systems Engineering has a lot to offer the serious practitioner. In

Introduction In the first four parts of this series, we have focused on the SysML modeling part of the systems engineering effort. While general-purpose modeling serves many purposes, some parts of design and analysis are best done with more specialized tools. The ability to keep multiple models consistent is the objective of Model-Based Engineering (MBE)

Introduction SysML models readily connect structure, behaviors, requirements, and analysis in a single model. We started to show behaviors back in Part 1 with a series of simple state machine behaviors. In this blog post, we show how SysML interaction elements and sequence diagrams can be used to model the message-based communication between different parts
