Building Executable SysML Model – Automatic Transmission System (Part 1)

SysML allow both structural and behavioral modeling of the system. SysML models can be formally interpreted and executed. Ones executed analysis can be performed at system level. Ones we are good with simulation results we can prototype. Using programmable Lego Mindstors NXT for prototyping is an out of the box way to test and demonstrate […]

Connection Between DoDAF and SysML

It is quite often we are asked about connection between DoDAF and SysML. They coexist together very well! Both are OMG standards (same comon metamodel behind), so everything is fully reusable and traceable. Positioning and connection points DoDAF framework provide tools to describe the enterprise architecture – starting from capabilities, going to operational level and […]

MBSE in Enterprise Architecture Using SysML and UPDM

MBSE (Model Based Systems Engineering) is the future of SE. MBSE helps to improve the productivity of systems developing by moving from document based approach to the modeling. However SysML is neither a modeling methodology nor a framework. Our clients reached the best results using SysML within the Defense Architecture Frameworks. The main identified benefits […]

A Free Sample Chapter, "Chapter 3: Block Definition Diagrams," From SysML Distilled

SysML Distilled: A Brief Guide to the Systems Modeling Language The Systems Modeling Language (SysML) extends UML with powerful systems engineering capabilities for modeling a wider spectrum of systems and capturing all aspects of a system’s design. SysML Distilled is the first clear, concise guide for everyone who wants to start creating effective SysML models. Drawing on […]

What are the most used MBSE methods, metrics, tools? OMG asked system engineering experts to help develop SysML standard

What is the most popular MBSE modeling method? What metrics are actually used and what value do they bring? What Modeling tools are used? What was the primary purpose of the model? Those and more than 50 additional questions (including open-ended responses) were provided by a sample of respondents from the system engineering community. The […]

Enabling MBSE by integrating SysML with PLM, CAD/CAE, Databases

SLIM (Systems LIfecycle Management) is a software environment for integrated model-based systems engineering, founded on SysML (OMG Systems Modeling Language) and PLM (Product Lifecycle Management) toolsets. With this approach, system engineers can develop and manage the high-level architecture of a system/product in SysML and simultaneously connect, communicate, and sync with detailed requirements, parts (bill of materials and […]

Formal Validation of Fault Management Design Solutions

The research was carried out at the Jet Propulsion Laboratory (NASA JPL) under a contract with the National Aeronautics and Space Administration and the European Southern Observatory (ESO). The work presented in this paper describes an approach used to develop SysML modeling patterns to express the behavior of fault protection, test the model’s logic by […]

Requirements Writing in SysML Guide

This document proposes structuring and styling rules that help writing requirements using the SysML language as well as specific MagicDraw capabilities that support this process. Prerequisites: basic MagicDraw knowledge; basic knowledge of the SysML language requirements part. The biggest issue users have when they start writing requirements using the SysML language is that there is […]
