4 Model-Based Systems Engineering MBSE specifies the system as a single evolving computer model, not a series of disconnected, static documents.

5 Model-Based Systems Engineering The documents can still be created from the model and they are self-consistent, generated from the same source of truth. When the model changes, new documents can be generated with the click of a mouse

6 Model-Based Systems Engineering But most of the engineering will still be done with the same tools (CAD/ CAE) and much of the detailed design information will still be stored in spreadsheets and databases, not in the SysML model. Operational concepts documents spreadsheets So, The System Model is the SysML Model plus CAD models analysis & simulation models

12 Basic SLIM Functions SysML PLM/Repository Connect Generate Check Update Execute Description SLIM creates a connection between existing elements in the SysML element and repository. This may be a simple traceable link or a detailed data mapping between element attributes. These connections are stored and managed by SLIM. SLIM generates an element on one side from an element on the other. SLIM manages a persistent connection between them. SLIM checks for changes at the repository end of a connection. This may include generation of a difference report. SLIM updates the element at one end of the connection based on the element at the other end. This may include changes in the element structure or attribute values. SLIM triggers execution of an element (e.g. a MATLAB function) managed in the repository as part of a SysML model execution.

13 Demonstration SLIM Plug-In for MagicDraw Scenario SE at Systems Integrator needs to build a SysML model of an unmanned aerial vehicle system using information from PLM and database repositories 13

14 Where is SLIM Going? New Architecture Elements: e.g., Requirements, Functions/Features New SysML Tools: Artisan, EA New Repositories: Enovia, Git, Subversion New Databases: Oracle, MS Excel SysML-MCAD: NX, Creo SysML-Requirements: CRADLE, DOORS, Integrity SysML-Simulation: Simulink, Modelica, Wolfram System Modeler New Capabilities will be driven by Customer Demand 14

15 SysML-CAD Visualization Step 2: A surrogate SysML block element is generated with the Creo parameters. This block represents the Creo model for the system engineer. Step 3: The surrogate SysML block element (and corresponding instance) is connected to the Creo model. System engineer can sync parameter values. Use Case 1 If a SysML element is connected to a CAD file, user can visualize the CAD file from the SysML dashboard 15

16 SysML-CAD Data Map Step 1: Select Creo assembly parameters of interest Use Case 2 Selected parameters from a CAD file are used to generate a corresponding SysML block and value properties.

17 SysML-CAD Data Map Step 2: A surrogate SysML block element is generated with the Creo parameters. This block represents the Creo model for the system engineer. Step 3: The surrogate SysML block element (and corresponding instance) is connected to the Creo model. System engineer can sync parameter values. Values read from Creo

18 Interoperability Challenge SLIM and OSLC are Complementary SLIM = Software for integrated MBSE (UI + API) OSLC = Specs + REST API in various PLM/ALM areas Connect, access, and identify information SysML SLIM 1 for all 1 for each OSLC adapter (does not exist today) Teamcenter, Windchill, MySQL,. Native SOA API Do useful things query, compare, generate, sync requires semantics SysML SLIM These models mean different things (semantic heterogeneity) SLIM provides specialized connection patterns and services CAD (NX, Creo) FEA (e.g. ANSYS) Math (Mathematica, MATLAB) Simulation (System Modeler, Simulink) Project Management (MS Project, Primavera) 18
