Description 2 0 Many of our customers in National Security Space NSS need help with architecture and modeling of both current and future systems 0 Customers have a difficult time relating and analyzing system of systems due to currently available methodologies and tools 0 Are we sure that SysML both the specification and tool implementations is appropriate for use on N88 programs I Want to understand spec limitations and tool capabilities I Provide guidance to customers considering using SysML o How does SysML relate to DODAF 7 THE AEROSPACE CORPORATION January 2007 24 Work to be Done 7 THE AEROSPACE 9 CORPORATION Work to be Done this Year 0 Model a ground system architecture in SysML 0 Objectives I Determine the successes and limitations of the SysML specification I Document the tool s modeling capabilities I Develop an executable model to analyze system behavior 9 Either cost or performance or both I Perform a trade study of design alternatives Assess how well the SysML models map to UML models Assess the learning curve involved 0 For systems engineers who are used to modeling functional breakdowns o For those already familiar with UML and objectoriented design 70 THE AEROSPACE Q CORPORATION January 2007 26 What You Will Need to Do 0 Develop plan schedule and deliverables for executing this project I Clarify scope I To be approved by customer 0 Become familiar with space ground systems 0 Apply the systems engineering method to I Implement the model in SysML I Analyze the executable model for design alternatives 0 Use Rational System Architect with the SysML plug in for all the work 7 THE AEROSPACE CORPORATION January 2007 27 What Aerospace Can Do For You 0 Provide a case study of a system modeled in Popkin I A NASA ground system focused on data archiving 0 Meet with you biweekly or more frequently as needed to assess your progress and answer ques ons 0 Provide access to experienced space system architectsmodelers 0 Help clarify actual customer use and needs for SysML o Facilitate the presentation of the results of this effort to professional societies such as INCOSE 7 THE AEROSPACE CORPORATION January 2007 28 References 7 THE AEROSPACE CORPORATION
