ABSTRACTThis article provides an overview of the requirements for the next generation Systems Modeling Language (SysMLR v2). The requirements are specified in the SysML v2 Request for Proposal (RFP) that was issued in December 2017 by the Object Management Group (OMGR). The issuance of the RFP culminates a one‐and‐a‐half‐year effort by the SysML v2 RFP Working Group to develop the requirements for SysML v2 that will improve support for model‐based systems engineering (MBSE). In particular, the requirements are intended to enhance the precision, expressiveness, and usability of SysML v2 relative to SysML v1. A complementary RFP entitled, “The SysML v2 API and Services RFP” is also being developed to enable interoperability between SysML modeling tools and other model‐based engineering tools.
