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 next FY. 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

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.
