Overview

The Decision Module in Delft-FEWS is used to implement decision logic and evaluation for barriers. With this module we can iteratively evaluate configurated decision rules. The configuration file of the Decision Module contains the definition of one or more Decision Trees. These Decision Trees defined in the Decision Module are associated with a Barrier definition which are defined by the Barriers configuration file.

When evaluating the decision logic, it is relevant to take into account the fact that the model state will change after the barrier state has been updated (changed). To evaluate the decision logic for subsequent steps in the process, this implies that we will need to re-run the model to take this state change into account. Also, if there are multiple barriers in our area of interest, this implies that if the state of one of these barriers changes, we need to update our model simulation before we can assess the decision logic for the other barrier(s).
