AbstractThis talk overviews Phase 1 experiences and lessons learned from an excavator testbed that interconnectssimulation models with associated diverse system models, design models, and manufacturing models. The goal

is to enable advanced model-based systems engineering (MBSE) in particular and model-based X (MBX) [1] in

general. Our method employs SysML as the primary technology to achieve multi-level multi-fidelity

interoperability, while at the same time leveraging conventional modeling & simulation tools including

mechanical CAD, factory CAD, spreadsheets, math solvers, finite element analysis (FEA), discrete event

solvers, and optimization tools. This work is sponsored by several organizations including Deere and Lockheed

and is part of the Modeling & Simulation Interoperability Team [2] in the INCOSE MBSE Challenge (with

applications to mechatronics as an example domain).

[1] The X in MBX includes engineering (MBE), manufacturing (MBM), and potentially other scopes and contexts

such as model-based enterprises (MBE).

Emerging Tools: Connecting a System Model

to Domain Models via SysML

Title: Composable Mission Framework for Rapid End-to-End Mission Design and SimulationPrincipal Investigator: Dr. Manas Bajaj, InterCAX LLC

Phase 1: Jan Jul, 2009 [NASA SBIR-08-1-S4.02-9130] NASA SBIR project

Technical Abstract: The innovation proposed here is the Composable Mission Framework (CMF)amodel-based software framework that shall enable seamless continuity of mission design and simulation

from early stage advanced studies to detailed mission design and development. The uniqueness of our

approach lies in using an open standard for systems modeling and design (SysML) to wrap mission modelsincluding the mission development process thus providing a coherent map of mission knowledge. InterCAX's

Composable Object technology provides the backend wrapping, model management, and simulation

orchestration capabilities to the visual SysML-based mission model at the front end.

The Composable Object technology has already demonstrated the ability to power SysML-based

models with math simulation capabilities for early design stages. ParaMagic is a commercially available tool

being used by early adopters of SysML at JPL. The Composable Object technology has also demonstrated

the ability to associate detailed design and simulation models such as those created in CAD and FEA tools.

However, a big gap exists in the SysML-based world for conceptual system design and the detailed systemdesign-based world. If the detailed system design and simulation models could be wrapped as SysML

objects and the simulations and workflows orchestrated by the Composable Object technology, it will cover

the entire gamut of complex system modeling and analysis world from trade studies and optimization to

project scheduling.

The key objective of Phase 1 is to wrap both conceptual and detailed system design and

simulation models as SysML objects which has not been done before, and to demonstrate continuity of

mission concepts from simple to detailed implementation.

AbstractThis presentation overviews work-in-progress experiences and lessons learned from an excavator testbed that

interconnects simulation models with associated diverse system models, design models, and manufacturing models. Thegoal is to enable advanced model-based systems engineering (MBSE) in particular and model-based X1 (MBX) in

general. Our method employs SysML as the primary technology to achieve multi-level multi-fidelity interoperability, while

at the same time leveraging conventional modeling & simulation tools including mechanical CAD, factory CAD,

spreadsheets, math solvers, finite element analysis (FEA), discrete event solvers, and optimization tools. This work is

currently sponsored by several organizations (including Deere and Lockheed) and is part of the Mechatronics &

Interoperability Team in the INCOSE MBSE Challenge.

Part 1: A Parametrics PrimerOMG SysML is a modeling language for specifying, analyzing, designing,

and verifying complex systems. It is a general-purpose graphical modeling

language with computer-sensible semantics. This Part 1 paper and its Part

2 companion show how SysML supports simulation-based design (SBD) via

tutorial-like examples. Our target audience is end users wanting to learn

about SysML parametrics in general and its applications to engineering

design and analysis in particular. We include background on the

development of SysML parametrics that may also be useful for other

stakeholders (e.g, vendors and researchers).

In Part 1 we walk through models of simple objects that progressively

introduce SysML parametrics concepts. To enhance understanding by

comparison and contrast, we present corresponding models based on

composable objects (COBs). The COB knowledge representation has

provided a conceptual foundation for SysML parametrics, includingexecutability and validation. We end with sample analysis building blocks

(ABBs) from mechanics of materials showing how SysML captures

engineering knowledge in a reusable form. Part 2 employs these ABBs in a

high diversity mechanical example that integrates computer-aided design

and engineering analysis (CAD/CAE).

The object and constraint graph concepts embodied in SysML

parametrics and COBs provide modular analysis capabilities based on

multi-directional constraints. These concepts and capabilities provide a

semantically rich way to organize and reuse the complex relations and

properties that characterize SBD models. Representing relations as non-causal constraints, which generally accept any valid combination of inputs

and outputs, enhances modeling flexibility and expressiveness. We

envision SysML becoming a unifying representation of domain-specific

engineering analysis models that include fine-grain associativity with other

domain- and system-level models, ultimately providing fundamental

capabilities for next-generation systems lifecycle management.

Part 2: Celebrating Diversity by ExampleThese two companion papers present foundational principles of

parametrics in OMG SysML and their application to simulation-based

design. Parametrics capabilities have been included in SysML to support

integrating engineering analysis with system requirements, behavior, and

structure models. This Part 2 paper walks through SysML models for a

benchmark tutorial on analysis templates utilizing an airframe system

component called a flap linkage. This example highlights how engineering

analysis models, such as stress models, are captured in SysML, and then

executed by external tools including math solvers and finite element

analysis solvers.

We summarize the multi-representation architecture (MRA) method and

how its simulation knowledge patterns support computing environments

having a diversity of analysis fidelities, physical behaviors, solution

methods, and CAD/CAE tools. SysML and composable object (COB)techniques described in Part 1 together provide the MRA with graphical

modeling languages, executable parametrics, and reusable, modular, multi-

directional capabilities.

We also demonstrate additional SysML modeling concepts, including

packages, building block libraries, and requirements-verification-simulation

interrelationships. Results indicate that SysML offers significant promise as

a unifying language for a variety of models-from top-level system models to

discipline-specific leaf-level models.

AbstractThis document formulates a vision for advanced collaborative engineering environments (CEEs) to aid in the design,

simulation and configuration management of complex engineering systems. Based on inputs from experienced SystemsEngineers and technologists from various industries and government agencies, it identifies the current major challenges

and pain points of Collaborative Engineering. Each of these challenges and pain points are mapped into desired

capabilities of an envisioned CEE System that will address them.

Next, we present a CEE methodology that embodies these capabilities. We overview work done to date by GIT on the

composable object (COB) knowledge representation as a basis for next-generation CEE systems. This methodology

leverages the multi-representation architecture (MRA) for simulation templates, the user-oriented SysML standard for

system modeling, and standards like STEP AP233 (ISO 10303-233) for enhanced interoperability. Finally, we present

COB representation requirements in the context of this CEE methodology. In this current project and subsequent phaseswe are striving to fulfill these requirements as we develop next-generation COB capabilities.

automation. He originated composable objects (COBs), the multi-representation architecture (MRA) for CAD-CAE

interoperability, and context-based analysis models (CBAMs)a simulation template knowledge pattern that explicitly

captures design-analysis associativity. This work has provided the conceptual foundation for SysML parametrics and its

validation.

He teaches this and related material, and is principal investigator on numerous research projects with sponsors

including Boeing, DoD, IBM, NASA, NIST, Rockwell Collins, Shinko Electric, and TRW Automotive. Dr. Peak joined the

GIT research faculty in 1996 to create and lead a design-analysis interoperability thrust area. Prior experience includes

business phone design at Bell Laboratories and design-analysis integration exploration as a Visiting Researcher at

Hitachi in Japan.
