CIM-OSA is an open architecture developed by the ESPRIT-AMICE organization composed of 21 companies and universities in the European Community after more than six years of hard work. The CIM-OSA architecture integrates the management and production of enterprises The process is regarded as a three-dimensional model composed of life cycle dimensions, view dimensions and general dimensions. Life cycle dimension refers to the three stages in the entire life cycle of CIM system development, from "requirement definition" to "design description" to "implementation description". Each stage has a model suitable for its needs and characteristics; view Dimension refers to the various aspects of the system that need to be modeled and their interrelationships. Here, it proposes four views of function, information, resources and organization; general dimension refers to a development process from general to special.
Compared with other CIM architectures, CIM-OSA has the advantages of comprehensiveness, completeness, openness, standardization and formalization, so it has become a pre-standard of the International Organization for Standardization. Many modeling frameworks are derived from CIM-OSA, or borrow the ideas of CIM-OSA to a large extent. However, its shortcomings are that there is no real methodology to guide the implementation of the modeling process, and part of the model framework is not perfect, so there is no commercial software that fully follows the CIM-OSA architecture. p>
