The CADRe system (Computer Aided Dispute Resolution) is a web-based software tool for
resource and environmental managers that converts information into insight to support the decision and policy making process. More then a common 'decision support system', the CADRe system was born out of a three-year collaboration between Sandia National Laboratories and the University of Texas Austin. The CADRe system allows users to directly interact with different models to receive real-time feedback to changes in input, and to examine output sent to custom built displays. The models can be of any temporal and/or spatial scale and can involve any number of different systems and/or sub-systems. Underneath the GUI, lies our powerful meta-heuristic optimization engine that intelligently searches the entire solution space to suggest alternate solutions that meet user defined criteria. This unique capability allows decision and policy makers to literally create solutions that were previously unforeseen.

While the CADRe system is a major development in the world of resource and environmental management, CADRe as a whole is more of a philosophy then a set of tools or models. Core to this philosophy is the necessity to convert information to insight. Resource management is a complex field that involves multiple interests and objectives as well as high degrees of uncertainty and variability. Further complications arise from the fact that decisions can have far reaching and unforeseen impacts beyond the system in question. Crucial to good decision making is the ability to factor in as much information as possible to gain understanding of how various decisions and policies impact different systems, and how those systems in turn, impact each other. As understanding and insight into the complex behavior and relationships of each of the systems gets better, the risk of making poor policy decisions is reduced. This insight can only be gained through the careful inclusion of scientific analysis that is openly executed in a collaborative manner. The purpose of the CADRe system is to streamline this process by:

  • Providing a single platform for which to explore multi-objective, multi-system problems,
  • Linking models of different temporal and spatial scales into one system,
  • Utilizing existing models and codes already developed for a specific problem,
  • Optimizing on user defined criteria to gain access to unforeseen solutions,
  • Customizing the GUI to meet the specific needs of each project, and
  • Including stakeholder involvement to gain consensus and buy-in during each step of
        the development process.
