The Ecosystem Management Decision Support System is heading toward version 5.5. Recent updates to the system include support for tactical planning (deciding which possible management actions are highest priority in a management unit). This feature is currently supported by both Criterium DecisionPlus, a multi-criteria decision support system (DSS) that has been part of EMDS since 2002, and VisiRule, a recently added DSS that uses graphically-based decision trees with powerful support from its underlying Prolog engine.
