A Way of Thinking About Model Analysis

Two means for organizing and discussing the growing number of activities concerned with critical examination of energy policy models are presented. The first is set out in the form of a tree with two main branches corresponding to the primary modes of conducting model analysis. The second is in the form of a 4 × 3 matrix whose rows designate the people who do model analysis and whose columns represent the circumstances under which they do it. The paper concludes with questions about the future of model analysis framed in terms of the categories developed.
