A minimally invasive model data passing interface for integrating legacy environmental system models

摘要: This paper presents the Model Data Passing Interface (MODPI). The approach provides fine-grained, multidirectional feedbacks between legacy environmental system models through read and write access to relevant model data during simulation using a bidirectional, event-based, publish-subscribe with message broker. MODPI only requires commented directives in original code an XML linkage file optional custom conversion module. Automated generation, compilation, execution reduce programming burden on modeler. Case study results indicated that required less modifications within each base both before after automated outperforming baseline subroutine approach. Performance overhead for was minimal use case, offering speedup some cases parallel execution. is much invasive than other techniques, potentially encouraging adoption by modeling community addition maintainability reusability of integrated code.
