This paper proposes a formal model for analysing the human-machine information processor that takes into account cost of performing information-gathering actions, communication costs and time constraints.
Abstract
Abstract Decision Support Systems (DSSs) are utilized to support a users decision process. One generally required characteristic of a DSS is that it be an interactive system. Generally the degree of interaction between the human and the system is such that one can view the information processing activity as being performed by the human-computer information processor. Although DSSs are fairly commonly used, there has been very little work done to develop a formal basis for the design of such systems which take into account the interactive nature of problem solving. In this paper we propose a formal model for analysing the human-machine information processor. The model takes into account cost of performing information-gathering actions, communication costs and time constraints. We illustrate the application of the model within the domain of categorization. A special case of the categorization problem called the “only-correct-guesses-count” problem is defined and analyzed within the context of the model.

Dart differs from previous approaches to diagnosis taken in the design-automation community in that it is more general and in many cases more efficient, and allows it to be applied to a wide class of devices ranging from digital logic to nuclear reactors.

This group's work in medical decision making has led them to formulate a framework for expert system design, in particular about how the domain knowledge may be decomposed into substructures, which proposes that there exist different problem-solving types, i.e., uses of knowledge, and corresponding to each is a separate substructure specializing in that type of problem-Solving.

A broad range of heuristic programs—embracing forms of diagnosis, catalog selection, and skeletal planning—accomplish a kind of well-structured problem solving called classification, which provides a useful framework for recognizing and representing similar problems, for designing representation tools, and for understanding why non-classification problems require different problem-solving methods.
