It recently acquired a plug-in system which was implemented using framework-assisted dependency injection, a pattern more typically used in enterprise rather than research software. We describe the extension points and the implementation of the plug-in system. The architecture makes it easier and safer to combine independently developed components to complex simulation models, compared to many ad-hoc solutions often found in research software.en380 Handel, Kommunikation, Verkehrtraffic simulationsoftware architecturedependency injectionConference Object1611-3349
