DAVID: Influence Diagram Processing System for the Macintosh

TL;DR

DAVID is a system designed for processing influence diagrams on Macintosh computers, enabling decision analysis by representing uncertainties, decisions, and goals graphically.

Contribution

It introduces a Macintosh-based influence diagram processing system that clearly distinguishes between decision variables, chance variables, and goals for improved decision analysis.

Findings

Supports graphical representation of influence diagrams

Facilitates decision-making under uncertainty

Enhances clarity in modeling decision problems

Abstract

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.
