Using XML in version management of chemical process models

Abstract

Process modeling develops models of chemical engineering systems to promote better understanding and allow simulated investigation. Currently, there are no standards for process models, and no tool that addresses all phases of development. Model knowledge is frequently lost in this conversion, due to improper documentation of models, and the lack of systematic management mechanisms to manage all the models concerned. The ability to reuse models or model parts would greatly reduce the resources required for model development. This paper presents a strategy and framework for reuse that is facilitated through the documentation, control and information management of the model development process. This is accomplished through the application of Software Configuration Management strategies, and increases portability of information encapsulated by using XML based models. Incorporated in this is the automatic determination of versions, variants and revisions of models to assist modelers in tracking the evolution of model instances. © Springer-Verlag Berlin Heidelberg 2005.
