From Family Trees to Decision Trees.
Trobian, Helen R.
This paper is a preliminary inquiry by a non-mathematician into graphic methods of sequential planning and ways in which hierarchical analysis and tree structures can be helpful in developing interest in the use of mathematical modeling in the search for creative solutions to real-life problems. Highlights include a discussion of hierarchical concepts, probability, and several types of tree structures; a description of the tree methodology used for an introductory course in ethics; a brief history of spatial and abstract hierarchies, the human hierarchy, and a hierarchy of personal achievement; an explanation of Saaty's four-level Analytic Hierarchy Process; a description of a method for quantifying relative values using the Pairwise Comparison Scale; and a discussion of tree structure use of specifying and evaluating goals as graphic aids to decision making. Detailed descriptions and diagrams are given of the use of the decision tree methodology in the ethics course, which includes several sessions on values; a module on decision analysis in ethics; a presentation of the concepts of probability, expected value, and quantitative methods of obtaining optimal value judgments in a biomedical situation; study materials; decision-making exercises to be completed by drawing trees; and assignments. Procedures for analyzing the trees are also provided. Several tables, diagrams, and a variety of examples of tree structures that have been used to facilitate research in several disciplines are included. (DJR)
