Decision Support Systems

Volume 5 Number 4 July/August 2006

Decision support systems (DSSs) can range from a basic flow chart or stack of GIS layers to a complex computer model that incorporates physical, economic, cultural, and regulatory attributes to evaluate any number of scenarios. Here, we focus on understanding how the more complex type of DSSs work, and how, where, and by whom they are being used to make water management decisions. As illustrated in several articles, one of the strengths of DSSs is their ability to allow stakeholders to “test” the effects of various management alternatives, which helps them better understand the processes and interactions that occur in the system.
