Spatial problems are often characterised by incomplete information, multiple conflicting evaluation criteria and a heterogeneous group of decision-makers. Implementation of existing analytical decision–making methods in a Spatial Decision Support System has been characterised by difficulties when dealing with uncertainty, criteria standardization, and group decision-making where there is no consensus. Another problem is the real or perceived difficulty of using such systems, leading to poor uptake by decision-makers. This paper discusses the development of a spatial decision support system (SDSS) using a new natural language approach to mitigate the abovementioned difficulties. The system is designed to aid site selection for large-scale infrastructure facilities at a strategic level, using a fuzzy multicriteria, multi-decision-maker framework and linguistic methods. We describe the theoretical basis of our approach, and its practical implementation in a GIS-based System. A real world site selection problem involving the location of a new industrial facility at Brisbane Airport (Australia) is also worked through.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
