Simulation & Analysis Using Sys. ML Dec 2008: Final Phase 1 Overview Presentation Experiences Applying Sys. ML in an Excavator Testbed and More Abstract This talk overviews Phase 1 experiences and lessons learned from an excavator testbed that interconnects simulation 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 Sys. ML 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 Sys. ML Title: Composable Mission Framework for Rapid End-to-End Mission Design and Simulation Principal Investigator: Dr. Manas Bajaj, Inter. CAX LLC Phase 1: Jan – Jul, 2009 [NASA SBIR-08 -1 -S 4. 02 -9130] — NASA SBIR project Technical Abstract: The innovation proposed here is the Composable Mission Framework (CMF)—a model-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 (Sys. ML) to wrap mission models including the mission development process thus providing a coherent map of mission knowledge. Inter. CAX's Composable Object technology provides the backend wrapping, model management, and simulation orchestration capabilities to the visual Sys. ML-based mission model at the front end. The Composable Object technology has already demonstrated the ability to power Sys. ML-based models with math simulation capabilities for early design stages. Para. Magic is a commercially available tool being used by early adopters of Sys. ML 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 Sys. ML-based world for conceptual system design and the detailed system design-based world. If the detailed system design and simulation models could be wrapped as Sys. ML 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 Sys. ML objects which has not been done before, and to demonstrate continuity of mission concepts from simple to detailed implementation. Copyright Inter. CAX – All rights reserved 36

Integrating Design with Simulation & Analysis Using Sys. ML— Mechatronics/Interoperability Team Status Report Abstract This 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. The goal is to enable advanced model-based systems engineering (MBSE) in particular and model-based X 1 (MBX) in general. Our method employs Sys. ML 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.

Simulation-Based Design Using Sys. ML Part 1: A Parametrics Primer Part 2: Celebrating Diversity by Example OMG Sys. ML™ 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 Sys. ML supports simulation-based design (SBD) via tutorial-like examples. Our target audience is end users wanting to learn about Sys. ML parametrics in general and its applications to engineering design and analysis in particular. We include background on the development of Sys. ML 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 Sys. ML 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 Sys. ML parametrics, including executability and validation. We end with sample analysis building blocks (ABBs) from mechanics of materials showing how Sys. ML 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 Sys. ML 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 noncausal constraints, which generally accept any valid combination of inputs and outputs, enhances modeling flexibility and expressiveness. We envision Sys. ML 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. These two companion papers present foundational principles of parametrics in OMG Sys. ML™ and their application to simulation-based design. Parametrics capabilities have been included in Sys. ML to support integrating engineering analysis with system requirements, behavior, and structure models. This Part 2 paper walks through Sys. ML 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 Sys. ML, 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. Sys. ML and composable object (COB) techniques described in Part 1 together provide the MRA with graphical modeling languages, executable parametrics, and reusable, modular, multidirectional capabilities. We also demonstrate additional Sys. ML modeling concepts, including packages, building block libraries, and requirements-verification-simulation interrelationships. Results indicate that Sys. ML offers significant promise as a unifying language for a variety of models-from top-level system models to discipline-specific leaf-level models.

Composable Objects (COB) Requirements & Objectives Abstract This 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 Systems Engineers 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 Sys. ML standard for system modeling, and standards like STEP AP 233 (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 phases we are striving to fulfill these requirements as we develop next-generation COB capabilities. Citation DR Tamburini, RS Peak, CJ Paredis, et al.

Leveraging Simulation Templates & Processes with Sys. ML Applications to CAD-FEA Interoperability Abstract Sys. ML holds the promise of leveraging generic templates and processes across design and simulation. Russell Peak joins us to give an update on the latest efforts at Georgia Tech to apply this approach in various domains, including specific examples with a top-tier automotive supplier. Learn how you too may join this project and implement a similar effort within your own company to enhance modularity and reusability through a unified method that links diverse models. Russell will also highlight Sys. ML’s parametrics capabilities and usage for physics-based analysis, including integrated CAD-CAE and simulation-based requirements verification. Go to www. omgsysml. org for background on Sys. ML—a graphical modeling language based on UML 2 for specifying, designing, analyzing, and verifying complex systems. Speaker Biosketch Russell S. Peak focuses on knowledge representations that enable complex system interoperability and simulation 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 Sys. ML parametrics and its validation. He teaches this and related material, and is principal investigator on numerous research projects with sponsors including Boeing, Do. D, 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.
