How to use IDRISI GIS for decision making

Decision making is the process that leads to a choice between a set of alternatives. Geographical decision-making means analysing and interpreting geographical information that is related to the alternatives in question. Decision making is often used in land suitability analysis, or site selection, as well as location allocation modelling. This paper, written in 1999 and later revised in 2002 will address some of the aspects of decision making and describe some of approaches used.
