Models as Microservices for Enabling Agile and Distributed MBSE

Models-as-Microservices (MamS) is a paradigm shift for agile and concurrent MBSE with globally distributed stakeholders. Model authors can publish models and data, in any format or database, as web-based microservices that can be dynamically composed and orchestrated to realize different engineering workflows for a given project or mission.nbsp; Model authors can configure the subset of model information, level of access control, and update frequency, e.g. publish only major revisions and not each iteration, when models are published as microservices. Once published, these microservices are accessible to all stakeholders via standard REST/HTTP APIs using open standards-based concepts.nbsp;Although each model/dataset is based on authoring tool-specific schema, the microservices published from those models are based on an extensible set of concepts in open standards, such as SysML 2.0, STEP (ISO 10303), and OSLC specifications. Engineering workflows can be configured by parametrically linking the endpoints (inputs/outputs) of the microservices using standard notation, such as SysML activity/parametric models, or BPMN process models. Once configured, the workflows can be executed automatically on a scheduled basis to run verification and validation campaigns and generate nightly builds of the system, such as technical data packages and corresponding reports.nbsp;The breadth of models includes, but is not limited to, systems engineering (e.g. SysML and UAF/UPDM), requirements (e.g. spreadsheets, ReqIF, DOORS, Jama), mechanical and electrical design (MCAD/ECAD, e.g. NX and Creo), engineering and manufacturing bills-of-materials (PLM eBOM/mBOM, e.g. in Windchill and Teamcenter), software modules (e.g. in Git repositories), project management (e.g. JIRA and MS Project), simulation (e.g. Simulink, Modelica, FEA/CFD models), models originating from home-grown tools, and data in common formats (e.g. CSV, Excel, XML, JSON, RDF).
