Alternative Generation

Alternative generation is the process of developing and presenting various solutions to a GeoDesign problem. Such alternatives could involve various possible actions such as “open new plant” or “allocate resources to administrative units.” Typically, a formal model supports a decision maker in determining the various alternatives. In spatial decision making, a model represents the decision situation by structuring and formalizing the available data and information about the decision problem. GeoDesign alternatives are derived by manipulation and analysis of the spatial data and information.

Although the above definition could be used for both generating design alternatives with software or for creating design alternatives by humans, in this context, we are using this term to mean the former.
