| ![]() Role of this Systems Modelling interoperability activity is to define an A&D strategy in terms of methods and standards to specify, exchange and integrate system models in the Aerospace and Defence industry. The Systems Modelling interoperability activity has started activities focusing on System Requirement management and exchange processes. It is planned to progressively extend to the full Systems Modelling scope (including system interfaces, system design and Verification & Validation). 2016 activities: Requirement exchange pilot case based on STEPIntroductionThe standardization of exchanges of PLM data becomes more and more important in the aeronautic industrial world for three main reasons:
STEP is an open and neutral standard managed by ISO, designed to cover the full scope of needs for the exchange and archiving of PLM data thanks to standards like the AP233, AP242 and AP239. These open formats are the most suitable solutions for ASD industries, covering all the needs of interoperability in PLM and addressing domains which can be complex, and interconnected. Public test caseA public test case illustrating the exchange of a requirements cascade has been defined. This covers several scenarios, e.g.:
The standard selected to support the exchange is the STEP requirement data model (last version currently updated through the STEP AP242 ed1 project, to be integrated in the next AP233 edition). Information is physically exchanged using XML files (STEP Part 28). This pilot demonstrates that STEP technology supports the required exchange functionalities. Objective: to steer the Requirement Management vendors to develop STEP AP242 interfaces for interoperability of requirement management information managed in configuration, related to PDM product structure. Note: AP242 data model for Requirement Management is consistent with STEP AP 233 “Systems Engineering” and AP239 PLCS Download filesYou can download the Pilot description and files:
