Towards an Integrated System Model:The Future Vision of No Magic’s MBSE Solution

MBSE Definition

2

“Model-Based Engineering (MBE): An approach to engineering

that uses models as an integral part of the technical baseline that

includes the requirements, analysis, design, implementation, and

verification of a capability, system, and/or product throughout the

acquisition life cycle.”

Final Report, Model-Based Engineering Subcommittee, NDIA, Feb. 2011

“Model-based systems engineering (MBSE) is the formalized

application of modeling to support system requirements, design,

analysis, verification and validation activities beginning in the

conceptual design phase and continuing throughout development

and later life cycle phases.”

INCOSE SE Vision 2020 (INCOSE-TP-2004-004-02, Sep 2007)

INCOSE Systems Engineering Vision 2025

Describes the projected state of MBSE as:

"Formal systems modeling is standard practice for specifying, analyzing,

designing, and verifying systems, and is fully integrated with

other engineering models. System models are adapted to the

application domain, and include a broad spectrum of models for

representing all aspects of systems. The use of internet-driven

knowledge representation and immersive technologies enable highly

efficient and shared human understanding of systems in a virtual

environment that span the full lifecycle from concept through

development, manufacturing, operations, and support."

Current Practice to Future Practice

Today: Standalone

Future: Shared system model

with multiple views, and

connected to discipline models

Challenges

• Can we have a single source of truth?

• Who is the master?

• Where configuration management is done?

• Who manages relations and their versions?

No Magic MBSE Ecosystem

Integration strategies

• File based approach• XMI for UML-SysML models

• ReqIF, CSV for Requirements

• FMI for simulation models

• API based• Local machine, JAVA vs C++ problems

• Web-based for remote access• REST API, OSLC

• Generative approach• Simulink, Modelica

• KBL, VEC, PSPICE for electrical harness/circuit

OSLC - Open Services for Lifecycle Management
