Object-oriented model integration in MIDAS (Manager's Intelligent Debt Advisory System)

Abstract

A description is given of a system for debt decision support which flexibly integrates optimization and simulation modeling and heuristic reasoning for nonexpert users through an object-oriented, domain-specific knowledge base. Stable domain relationships and mathematical procedures are encapsulated in domain object classes; domain object instances are combined to form common model representations manipulated by operators specific to each model type. The approach is applicable in domains in which stable entities and interactions exist and in which model flexibility results from varying combinations of entities, conditions which are found in many financial and other business modeling situations.<>
