Abstract: Decision support systems for users without modelling expertise require domain-specific modelling knowledge to translate between conceptual and mathematical problem views. In complez, dynamic decision situations using multiple model types, the system must create and modify individual models to reflect changing domain conditions and assumptions, maintain consistency among different models in the same decision situation and allow communication among models for their complementary use, all without relying on user expertise. This paper describes a system for debt decision support which flexibly integrates optimization and simulation modelling and heuristic reasoning for non-expert 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 modelling situations.

Model management systems: an overview
Robert W. Blanning
- 01 Jan 1993
TL;DR: In this paper, the authors examine three central topics in model management: model base structure and its correspondence to network and relational data base structures, model base processing and the application of artificial intelligence to model interfacing, integration, construction, and interpretation.

The evolution and problems of model management research
TL;DR: Before model management systems can be widely used in organizations, model management researchers must explore systems that address all areas of the task and design level dimensions.

A formal analysis of the model management literature
Q. B. Chung,Robert M. O'Keefe +1 more
TL;DR: An extensive bibliography of the archival material on model management is presented, and an analysis of that material shows that the three general approaches to model management can be observed, called here the data-model analogy, knowledge-based and model-representation approaches.

A framework for representing knowledge
Marvin Minsky
- 01 Jun 1974
TL;DR: The enormous problem of the volume of background common sense knowledge required to understand even very simple natural language texts is discussed and it is suggested that networks of frames are a reasonable approach to represent such knowledge.

Mark J. Stefik,Daniel G. Bobrow +1 more
TL;DR: Object-Oriented programming has a long history in simulation programs, systems programming, graphics, and AI programming as discussed by the authors, including message passing as in ACTORS and multiple inheritance as in FLAVORS.

A Generalized Decision Support System Using Predicate Calculus and Network Data Base Management
TL;DR: This paper shows how first-order predicate calculus can be used as a language for formally stating modeling knowledge and how knowledge stated in this manner can be subjected to the resolution principle.
