A geographic information system-based decision support system (GISDSS) for facility location

Due to the strategic impact of a facility location decision, a location search requires thorough analysis of numerous location factors. The difficulties in multi-factor analysis of location decisions have been challenged by many location researchers. This research study proposes the development of a novel geographic information system-based decision support system (GISDSS) to support high quality decision making in the facility location domain. A review of past location studies was conducted to identify the major considerations for locating a facility and to develop a taxonomy of location factors for Thailand. The GISDSS incorporates a chromatic representation location model and vastly accepted location factors. A geographic information system (GIS) is used with the location model to manipulate data and identify suitable sites. The model analyzes input data and recommends the best locations through the hue, saturation and value (HSV) color model.
