JWST Integrated Modeling Environment

1. James Webb Space Telescope JWST Integrated Modeling Environment

2. The Task At Hand • Create a tool to integrate the people, processes and data used to conduct the Integrated Modeling effort for JWST. • Requirements gathered from both the integrated modeling lead and from engineering discipline leads (who interact with the tool most often)

3. Defining a Solution • The tool should: • build an archive of analysis results, including the documentation that identifies the assumptions and data elements used for each analysis. • satisfies 400-PG-1440.7.2A, “Retention of Program and Project Technical Records by the Code 400 Directorate Library” • satisfies the need for “knowledge capture” • provide organized, efficient communication of analyses and their statuses. • provide traceability to software types and versions used for each step of the analyses. • allow for the reuse of previous analysis results.

4. Approach • Goals are to support integrated modeling team and their engineering processes • Capture processes and place under configuration control • Facilitate process execution • Capture all assets used in each process step, provided by engineering team • Team evaluated COTS solutions and external NASA solutions • Potential MatLab/Simulink implementation, costly development to enable knowledge capture • AFRL solution showed potential but mostly developmental • Other COTS solutions either required extensive development, delays due to unavailable software, or missed major elements of either workflow creation, configuration control, and extendibility • Turned to internal NASA network to identify possible working solutions • Leveraged MSFC and LaRC efforts in Space Launch Initiative (now Next Generation Launch Technologies) engineering environment efforts in Code R • Code R investment of 1.5 Years and many $M • Established strategic partnership with Parametric Technologies Corp. (PTC) • Also supporting LISA project with ramp up end of Summer into nextFY. Similar goals and level of support as JWST.

5. Solution Architecture • Leverage existing cross project framework, hardware, and software in Code 592 • Build from the Virtual System Design Environment (VSDE) capabilities • JWST Integrated Modeling activity already has users using VSDE capabilities • Purchase and leverage Agency investment with Windchill product modules • Windchill is a Product Lifecycle Management application from Parametric Technology Corporation. • With LaRC direction and guidance we licensed elements of Windchill version 6.2 as core foundation • Windchill provides rich capabilities for managing configurations, workflows, data and access control through a single web-based environment. • Developed customized front end and integration software in JAVA, JSP, and XML

6. At-a-Glance The Interface Menu: • Individual User Worklist • Model and Document Repository with Baseline Creation Capability • Pre-defined Jitter and Stop Analysis Workflows • Soon to be added: Customizable (Ad Hoc) Analysis Workflows

7. Worklist • Each user is presented with their unique worklist upon entering the IME. • Their activities are tracked as Potential, Accepted and Complete. • An engineer can accept an analysis task and immediately navigate to retrieve the details of the analysis and download the related models and documents. • The Filter option in the toolbar is provided for Managers and Administrators. It modifies the worklist view to display the analysis tasks based on the population selected.

8. Models & Documents The Model Repository allows for the creation of a file structure and project assembly. The Project File Manager provides the ability to fully customize both the file and structure hierarchies.

9. Models & Documents: cont. • The Project File Manager accepts any file type. • Document Associations • Allows linking between documents. • Allows document association to Assembly parts

10. Analysis Management • Analysis Management can be accomplished at the project level and at the component analysis workflow level. • The project level row depicted represents a single Jitter Analysis Workflow with a view into the status of each of the component analyses. • The User has the ability to review the workflows based on their statuses: Running, Suspended, Executed or Terminated. • The “Actions” drop down selection is present for authorized users allowing for the Creation, Suspension, Completion and Termination of the analysis workflows.

11. Analysis Management – cont. • Analysis Summary View – also available at the Analysis Workflow Level • Lists Details of the analysis. • Displays the data dictionary attributes for the analysis. • Additional Views Listed in the drop down selection: • Models • Documents • Workflows • Supporting Analysis • Dependant Analysis • Analysis History

12. Solution Specifications • Technical Requirements: • Hardware: • 1 Windchill Server • 1 Oracle Server • Software • Windchill 6.2.6 • Desktop Applications • Java 1.3.1 Plug-in • ProductView

13. JIME, the JWST Integrated Modeling Environment • A tool to integrate the people, processes and data used to conduct the Integrated Modeling effort for JWST. • JIME builds an archive of analysis results, including the documentation that identifies the assumptions and data elements used for each analysis. • JIME provides organized, efficient communication of analyses and their statuses. • JIME provides traceability to software types and versions used for each step of the analyses. • JIME allows for the reuse of previous analysis results.
