ROME: A Repository to Support the Integration of Models over the Lifecycle of Model-based Engineering Processes

摘要

Process modeling is currently performed by using a number of incompatible tools. The heterogeneous storage formats and systems of these modeling tools limit the reuse of models because semantic relationships among models originating from different or even the same tool cannot be maintained. A repository is proposed as a central storage system for models from various sources represented in various formats. The repository holds models representing chemical engineering and physics concepts by a conceptual data model rather than as mathematical equations or some programming language code. The conceptual representation of a model is accompanied by tool specific representations and documentation, enhancing the use of models over the lifecycle of model-based engineering processes such as chemical process design. The conversion among different tool formats is simplified by reducing the number of required converters if tools are connected to the repository instead of integrating them pair-wise.
