WIKI GUIDE
Complementing the IFs Training Manual, the purpose of this guide is to facilitate the development of scenarios with the International Futures (IFs) system. This manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?).
This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.
