DAVID: Influence Diagram Processing System for the Macintosh
This work provides a tool for decision-makers to model and solve influence diagrams, but it is incremental as it applies existing methods to a new platform.
The paper introduces DAVID, a system for processing influence diagrams on the Macintosh, which are directed graphs representing uncertainties as probabilities to distinguish between decision and chance variables with an explicit goal for solution.
Influence diagrams are a directed graph representation for uncertainties as probabilities. The graph distinguishes between those variables which are under the control of a decision maker (decisions, shown as rectangles) and those which are not (chances, shown as ovals), as well as explicitly denoting a goal for solution (value, shown as a rounded rectangle.
