Model-Based Systems Engineering (MBSE) provides a promising approach to manage this complexity by enabling consistent and structured system representations. While domain-specific modeling languages (DSMLs) can tailor MBSE methods to specific domains, existing approaches often lack standardized semantics, user guidance, and tool support to ensure consistent model creation and verification. This paper introduces a DSML framework tailored for the conceptual design of production systems, integrating both methodological guidance and standard-based domain knowledge. The approach builds upon the Software Platform Embedded Systems (SPES) framework and extends Systems Modeling Language (SysML) through the Unified Modeling Language (UML) profile mechanism, providing clear modeling constructs, viewpoint-specific diagram types, and automated consistency checks. To enhance comprehensibility and domain alignment, the framework incorporates supplementary DSMLs that capture structures and semantics from established industrial standards. The proposed method is evaluated using an aircraft production case study, demonstrating improved applicability of MBSE for the conceptual design of complex production systems.<\/jats:p>","DOI":"10.3390\/systems14020150","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T14:35:46Z","timestamp":1769783746000},"page":"150","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Domain-Specific Modeling Language for Production Systems in Early Engineering Phases"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0946-7742","authenticated-orcid":false,"given":"Lasse","family":"Beers","sequence":"first","affiliation":[{"name":"Institute of Automation Technology, Helmut Schmidt University, 22043 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8251-837X","authenticated-orcid":false,"given":"Hamied","family":"Nabizada","sequence":"additional","affiliation":[{"name":"Institute of Automation Technology, Helmut Schmidt University, 22043 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maximilian","family":"Weigand","sequence":"additional","affiliation":[{"name":"Institute of Automation Technology, Helmut Schmidt University, 22043 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alain","family":"Chahine","sequence":"additional","affiliation":[{"name":"Airbus Operations GmbH, Kreetslag 10, 21129 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8383-5323","authenticated-orcid":false,"given":"Felix","family":"Gehlhoff","sequence":"additional","affiliation":[{"name":"Institute of Automation Technology, Helmut Schmidt University, 22043 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1922-654X","authenticated-orcid":false,"given":"Alexander","family":"Fay","sequence":"additional","affiliation":[{"name":"Chair of Automation, Ruhr University Bochum, 44801 Bochum, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1016\/j.promfg.2018.06.036","article-title":"Model-based systems engineering for machine tools and production systems (model-based production engineering)","volume":"24","author":"Scheifele","year":"2018","journal-title":"Procedia Manuf."},{"key":"ref_2","unstructured":"AIRBUS (2025, January 15).
