DEFINITION A spatial decision support system (SDSS) is an interactive, computer-based system designed to support a user or a group of users in achieving a higher effectiveness of decision making while solving a semi-structured spatial decision problem [10]. It lies at the intersection of two major trends in the spatial sciences: geographic information sciences (GIS) and spatial analysis [10]. W...

Decision Support Systems (DDS) have developed to exploit Information Technology (IT) to assist decision-makers in a wide variety of fields. The need to use spatial data in many of these diverse fields has led to increasing interest in the development of Spatial Decision Support Systems (SDSS) based around the Geographic Information System (GIS) technology. The paper examines the relationship be...

Spatial decision support systems (SDSS) are generally employed in decision problems, in which spatial dimensions play a significant role. They have a satisfactory record in a wide range of problems and in various circumstances. SDSS Applications include land use planning, nuclear waste disposal facility location, water resource management, habitat site development, health care resource allocati...

Crime investigation have gained attention among multidisciplinary domain experts due to severity of impact strategic decision making and crime management. Current study develops support tools by introducing spatial system for investigating crime. Spatial analysis can be integrated into robust analysis. framework comprises four main components; (I) database, (ii) knowledge-base, (iii) user inter...

Technology and infrastructure both play key roles in achieving the optimisation of spatial data to support decision-making, in the spatial data community. Many institutional and technical initiatives have arisen in response to the increase in quantity and improving quality of spatial data to help users to structure the influx. However, there are persistent challenges to integrating institutiona...

Spatial Decision Support Systems (SDSS), which support spatial analysis and decision making, are currently receiving much attention. Research on SDSS originated from two distinct sources, namely, the GIS community and the DSS community. The synergy between these two research groups has lead to the adoption of state of the art technical solutions and the development of sophisticated SDSS that sa...

In this paper we describe how a well­designed Spatial Decision Support System (SDSS) may facilitate initial (immediate) decision making, while establishing a robust foundation and framework for improving effectiveness over time as new data and knowledge becomes available. 'Smart Knowledge Capture' is a set of methods for rapidly developing a strong SDSS for adaptive management. We review som...

This dissertation consists of three essays that propose designs and theoretically-based evaluations of two novel decision support systems (DSS): a web-based spatial DSS (SDSS), a dialectic DSS (DDSS), and a comparative analysis of subjective and objective measures of system success in terms of decision process and outcome. In the first essay, a web-based SDSS that utilizes the latest advances i...

The continuing development of DSS applications requires that new technologies be exploited to allow new classes of decision be supported. This paper discusses the use of a Geographic Information System (GIS) as a Decision Support System (DSS) generator to create Spatial Decision Support Systems (SDSS). Many important areas of DSS application, such as routing or marketing, make use of spatial in...

Spatial decision support systems (SDSS) are decision support tools which have been used widely in addressing complicated issues involving a spatial component. The use of SDSS has increased greatly over the last few decades especially in fields such as planning, natural resources management, and environmental science. Traditionally, SDSS have been developed with Geographic Information Systems (G...
