Developing Model Strings for Model Managers

Klein, Gary

ABSTRACT: Models are a key component in the decision-making process. Model managers have been proposed to select and direct the use of models in a decision setting. A limitation of model managers is their inability to optimally integrate several models to arrive at a decision. A scheme to overcome this limitation is presented. By specifying input requirements to each model and outputs available from each model, a string of models may be developed. An implicit enumeration algorithm ensures a feasible string of models for a required output and composes the string in optimal form according to a user-defined objective. The algorithm may be used in conjunction with existing model management techniques.
