Distributing models to various users can be difficult and prone to error, and therefore may negatively reflect on the program. Model distribution typically involves users downloading and installing the model following setup instructions. However, if this step is not handled correctly, the model is not able to be used correctly. Deploying a model through a web interface allows the user to focus on running the model rather than ensuring the model is setup correctly. The eRAMS/CSIP platform is designed to provide visual tools for models to be parameterized and connected to input data (eRAMS), and run using a remote web …
