Abstract: The concepts of multiobjective decision making utilizing embedded computer simulation models and dimensionless scoring functions are described in the context of a decision support system (DSS). This methodology consists of procedures to help make practical decisions using simulation models when the decision makers are faced with multiple, often conflicting, objectives. An example application describes a decision support system for design or remediation of shallow land burial systems to control release of radioactive and hazardous chemicals into the environment. Applications under development include selection of best farming practices to minimize water pollution from nutrients and pesticides.
