The JWST Integrated Modeling Environment

The growth of distributed teams and their fluctuating membership has introduced new challenges in the areas of collaboration and data management. The development of an environment to integrate people, processes and data is the catalyst behind the JWST Integrated Modeling Environment. The environment required a product that was robust enough to handle life cycle management, configuration management, visualization tools, and collaboration tools. The JWST Integrated Modeling Environment is built using Windchill, a Parametric Technology Corporation product. The partnership between NASA/GSFC/JWST, CSE Corp and PTC has resulted in a product that allows for the implementation and administration of diverse integrated modeling environments. The key features include creating, managing and developing modeling analyses over their entire life cycles, publishing model and analysis information for availability throughout the user community and managing legacy information without regard to original formats, database organizations or computing platforms. This presentation will discuss the motivation for the Integrated Modeling Environment, early results and walk through its usage in this specific example for JWST.



Mr. Johnny Medina is a Computer Engineer in the Systems Engineering Services & Advanced Concepts Branch, Code 592 providing Information Based Systems Engineering (IBSE) support to the JWST program in the areas of integrated modeling environment, distributed collaboration, and large scale information systems support life-cycle engineering. Mr. Medina has worked in the area of IBSE for three years now in agency local work for such teams as the Integrated Mission Design Center. Current activities include integrated modeling for the LISA mission, support to the Agency Engineering for Complex Systems Program for Risk Management Tools, Advanced Engineering Environments (AEE) and other related areas. Mr. Medina has a Master's Degree in Computer Graphics & Multimedia, and Bachelor's Degree in Computer Science and has been working for Goddard since 1990.

Mr. Gary Mosier is a systems engineer at the Goddard Space Flight Center, where he has been employed since 1987. Currently, his primary assignment is lead for Integrated Modeling and Systems Analysis on the James Webb Space Telescope project. He has published papers based on his work at Goddard in the areas of robotics, spacecraft attitude control systems, and multi-disciplinary modeling and simulation.

Mr. Christopher Stone and Mr. Chris Holtery of Constellation Software Engineering, are consultants to Code 592 in research & development of Enterprise IT capabilities such as the collaborative workspaces and other IBSE elements. Constellation Software Engineering provides NASA with key technologies and expertise in enterprise and web-based workflow technologies along with the design methods which enable the products developed within Code 592.
