An integrated modelling approach for identifying promising technologies to address waste management problems

A panel of technical experts is responsible for evaluating over 400 technology proposals in order to identify a limited number of the most promising for potential use in a future plutonium processing facility. A problem-driven, integrated modelling, decision-support framework has been conceptualized to facilitate this decision making effort. This integrated approach to planning utilizes a variety of modelling structures including Flowsheeting, Analytic Hierarchy Process, Linear and Goal Programming, and Object-Oriented Discrete Event Simulation. These models have been instrumental in improving communication among scientists, planners and model builders; increasing understanding of the potential for certain plutonium process technologies; providing insights into process technology interrelationships; and promoting a relatively objective basis for recommending further development for a select set of evolving process technologies.
