The proposed DSS framework may represent a useful guide to inexpert users in developing their own DSS. First of all, the general architecture of the DSS structure is not specifically tailored to coastal lagoon management problems, and is therefore directly applicable to other decision problems arising in water resource management, or even in different domains. Whatever the application is, it enables a clear identification of variables and cause–effect relations, thus driving the choice of appropriate models and tools. Moreover, the modular structure allows for an easy update of the DSS as soon as new (e.g., more accurate or less time-consuming) versions of the models are made available. Finally, it makes the role of uncertainty on uncontrollable factors and models explicit, and provides a simple, statistical way to take into account the effects of uncertainty on the DSS outcomes.
