THE CFD TOOL; A PROTOTYPE FOR HANDLING THE TIME DIMENSION IN COMPLEX MULTI-CRITERIA SPATIAL DECISION MAKING

摘要

Real world phenomena, in opposite to phenomena of an idealised mathematical or abstract world, are often vague, contradictory, and incomprehensible. However, in many cases it has proven suitable to handle such real life situations with a fuzzy approach. Further, decisions about our physical environment often are of a multi-criteria nature. However, basic methodologies for such multi-criteria fuzzy decision support have already been developed. Based on those works, we have further developed and tested an Ordered Weighted Average Procedure (OWA-procedure) for decision support in complex localisation decisions in physical planning. However, the OWA-procedure in its current form is not able to capture the full complexity of most real decision situations. For example, in most real world situations there is not just one decision but a suite of decisions that are at stake. Hence, in this paper a Continuous Fuzzy Decision Management Tool (CFD- tool), i.e. a system capable of managing a set of decisions over a prolonged time period will be discussed.
