SMIF (interface)

SMIF stands for the Standard Model Interface. It is a framework and a set of conventions designed to facilitate the coupling and integration of complex, computationally intensive models. Primarily used in the fields of infrastructure planning and urban systems modeling, SMIF allows different models representing diverse aspects of a system (e.g., energy, water, transport) to exchange data and interact with each other in a coordinated manner.

The key principle behind SMIF is to define a clear interface that allows models to be agnostic to the specifics of other models in the coupled system. This is achieved by using a standardized format for data exchange, often involving time series or tabular data. This allows models developed independently, potentially in different programming languages and with varying temporal and spatial resolutions, to be connected and simulate the behavior of a complex system as a whole.

SMIF acts as a mediator, managing the flow of information between models. It defines a common time horizon, ensures synchronization of simulations, and handles data conversion between the different formats used by individual models. This modular approach promotes reusability of models and reduces the complexity associated with building integrated systems.

While SMIF itself provides the framework and conventions, specific implementations may vary depending on the needs of the application. It focuses on enabling communication and data exchange rather than prescribing specific modeling techniques or data formats beyond the core interface requirements. The goal is to provide a flexible and extensible platform for integrated modeling, allowing researchers and practitioners to combine diverse modeling capabilities to address complex problems.
