Abstract for: Entity-based asset modeling, a databased model for infrastructure

Asset related SD applications have some specific needs. This paper is about infrastructure utilization and maintenance. The model runs on different aggregation levels and asset data-management is an important part of the application: therefore the application is entity/data based. In the presentation we will show our Ventity solution for this. It will highlight: - the specific requirements using a database for SD-modeling and - an entity-based approach (object oriented) to system dynamics modelling
