The paper by Huber (Huber, G. P. 1983. Cognitive style as a basis for designing MIS and DSS: much ado about nothing? Management Sci. 29 (5) 567--579.) stimulates further comment. While his conclusions that cognitive styles research has not served and will not serve as a satisfactory basis for...

We focus on ways of combining simple database models with managerial intuition. We present a model and method for isolating managerial intuition. For five different business forecasting situations, our results indicate that a combination of model and manager always outperforms either of these...

Planning languages and spreadsheet systems are very popular, and the number of new users is increasing dramatically. On larger computers, IFPS, System W, and FCS-EPS are among the most widely used systems; while on personal computers, Multiplan and 1-2-3 enjoy great popularity. Currently, such...

Rapid advances in information technology have brought decision makers the mixed blessing of an increasingly vast amount of easily available data. Designers of decision support systems (DSS) have focused on incorporating the latest technology with little attention to whether these new systems are...

This paper describes some rules for combining component models into complete linear programs. The objective is to lay the foundations for systems that give users flexibility in designing new models and reusing old ones, while, at the same time, providing better documentation and better...

Most decision support systems (DSS) contain stored data, data analysis procedures, and decision models. However, many DSS have grown to the point that the average end user is presented with a bewildering array of information resources that are difficult to manage in an effective manner. As a...

A research prototype implementation has been evolving for several years in parallel with the vision, theory, language, and applicative aspects of structured modeling. The objective of this article is to describe the capabilities of this implementation as it now stands, and to comment on how it...

Studies conducted in recent years have shown that outcome feedback in dynamic decision-making tasks does not lead to improved performance. This has led researchers to examine alternatives to outcome feedback for improving decision makers' performance in such tasks. This study examines the...

Expert systems often employ a weight on rules to capture conditional probabilities. For example, in classic rule-based settings, Pr(h | e) = x is used to mean "If e is known to be true then conclude h is true with probability x." Further, other probability-based approaches, such as influence...

We present a new framework for model management based on system concepts and theory. Underlying the framework is a set of meta-modeling concepts that are useful in capturing the semantics of the modeling process in a modeling environment. These concepts include the notions of a general-model...
