However, the integration of heterogeneous devices within IIoT systems presents substantial challenges, primarily due to the diversity in device hardware, protocols, and functionalities. In this paper, we propose a new pattern language specifically designed to enhance interoperability and operational efficiency across industrial settings. Drawing from a case study of the State Company for Automotive Industry (S.C.A.I.) in Iraq, this study details the development and integration of eleven interrelated patterns. These patterns were carefully combined based on identified relationships, forming a comprehensive pattern language that addresses key aspects of system heterogeneity, including device communication, data security, and system scalability. The pattern language was validated using the Delphi process theory, engaging industry experts to refine and optimize the framework for practical application. The implementation of this pattern language led to significant improvements in system integration, enabling seamless communication between diverse devices and enhancing operational workflows. The case study demonstrates the practical viability of the proposed pattern language in enhancing interoperability within real-world Industrial Internet of Things (IIoT) applications. Furthermore, the replicable nature of this framework makes it a valuable resource for other industrial environments seeking to harness the power of IIoT technologies.<\/jats:p>","DOI":"10.3390\/info15100595","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T07:19:37Z","timestamp":1727680777000},"page":"595","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Applying Pattern Language to Enhance IIoT System Design and Integration: From Theory to Practice"],"prefix":"10.3390","volume":"15","author":[{"given":"Hasanain Hazim","family":"Azeez","sequence":"first","affiliation":[{"name":"MDSE Research Group, Department of Software Engineering, University of Isfahan, Isfahan 81746-73441, Iran"},{"name":"Faculty of Computer Science and Information Technology, University of Wasit, Kut 52001, Iraq"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5113-7689","authenticated-orcid":false,"given":"Mohammadreza","family":"Sharbaf","sequence":"additional","affiliation":[{"name":"MDSE Research Group, Department of Software Engineering, University of Isfahan, Isfahan 81746-73441, Iran"}]},{"given":"Bahman","family":"Zamani","sequence":"additional","affiliation":[{"name":"MDSE Research Group, Department of Software Engineering, University of Isfahan, Isfahan 81746-73441, Iran"}]},{"given":"Shekoufeh","family":"Kolahdouz-Rahimi","sequence":"additional","affiliation":[{"name":"MDSE Research Group, Department of Software Engineering, University of Isfahan, Isfahan 81746-73441, Iran"},{"name":"School of Arts, University of Roehampton, London SW15 5PH, UK"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"doi-asserted-by":"crossref","unstructured":"Jain, S., and Chandrasekaran, K.
