Rethinking of Framework and Constructs of Enterprise Architecture and Enterprise Modelling Standardized by ISO 15704, 19439 and 19440

摘要

Enterprise Architecture (EA) and Enterprise Modelling (EM) are systems engineering tools to understand, design, develop, implement and integrate complex enterprise and information systems. ISO 15704, 19439 and 19440 define fundamental concepts and principles of EAs and EMs, which are emphasized as the top standards of smart manufacturing by NIST's smart manufacturing ecosystem and relative standardization roadmap. Since the three international standards will soon be subject to revision, this paper rethinks the basic principles of EAs and EMs, and presents a General Enterprise Modelling (GEM) framework and a relative EA (GEM-EA). GEM-EA provides tools and methodology of model-based systems engineering (MBSE) to enterprise and automation systems integration. GEM involves a set of models and methods to describes different aspects of a system and covers its lifecycle. GEM and GEM-EA can greatly facilitate the process of enterprise diagnosis, business process reengineering and information system implementation.
