Internet, GIS and Interactive Decision Maps

Abstract

This paper presents on the Interactive Decision Maps (IDM) technique. The IDM technique helps to apply Geographical Information Systems (GIS) in the context of spatial decision problems involving large number of varieties. It provides fast and easy to understand display of decision information about systems of efficient tradeoffs (decision maps). Information on feasible combinations of three to seven performance indicators (evaluation criteria) and on efficient tradeoffs between them can be displayed. In a decision process, this information helps to indicate a preferable feasible goal on a decision map by a simple mouse click. Then, a decision alterna tive resulting in the feasible goal is computed immediately. In negotiation procedures, the IDM technique helps to transform negotiations into navigation on decision maps. The IDM-based negotiation support procedures accomplish the main idea of Principled Negotiations: decisions are computed after a balanced combination of interests has been negotiated. In spatial decision and negotiation problems, the computed decision alternatives are displayed in GIS. Since the interaction among user and computer in IDM is quite simple, it can be 119 implemented via computer networks. Here, we restrict ourselves to open networks (actually, the Internet). Being implemented in the Internet, the IDM technique can help any computer-literate person to develop independent strategies for solving various important problems. An Internet demo version for developing a strategy for a regional economic problem has been established at the Web (http://www.ccas.ru/mmes/mmeda/resource/). The concept of IDM-based negotiations via Internet devoted to collaborative decision making on local and regional problems is outlined.
