These are spatial decision support\r\nsystems (SDSS) integrating intelligent systems techniques (Genetic Algorithms, Neural\r\nNetworks, Expert Systems, Fuzzy Logic and Nonlinear methods) with traditional modelling and\r\nstatistical methods for the analysis of spatial problems.\r\nThe principal aim of this work is to verify the feasibility of heterogeneous systems for\r\nspatial decision support derived from a combination of traditional numerical techniques and\r\nintelligent techniques in order to provide superior performance and functionality to that achieved\r\nthrough the use of traditional methods alone.\r\nThis thesis is composed of four distinct sections: (i) a taxonomy covering the\r\nemployment of intelligent systems techniques in specific applications of geographical\r\ninformation systems and SDSS; (ii) the development of a prototype ISDSS; (iii) application of\r\nthe prototype ISDSS to modelling the spatiotemporal dynamics of high technology industry in\r\nthe South-East of England; and (iv) the development of ISDSS architectures utilising\r\ninterapplication communication techniques.\r\nExisting approaches for implementing modelling tools within SDSS and GIS generally\r\nfall into one of two schemes - loose coupling or tight coupling - both of which involve a tradeoff\r\nbetween generality and speed of data interchange. In addition, these schemes offer little use\r\nof distributed processing resources.\r\nA prototype ISDSS was developed in collaboration with KPMG Peat Marwick's High\r\nTechnology Practice as a general purpose spatiotemporal analysis tool with particular regard to\r\nmodelling high technology industry. The GeoAnalyser system furnishes the user with animation\r\nand time plotting tools for observing spatiotemporal dynamics; such tools are typically not found\r\nin existing SDSS or GIS. Furthermore, GeoAnalyser employs the client/server model of\r\ndistributed computing to link the front end client application with the back end modelling\r\ncomponent contained within the server application. GeoAnalyser demonstrates a hybrid approach\r\nto spatial problem solving - the application utilises a nonlinear model for the temporal evolution\r\nof spatial variables and a genetic algorithm for calibrating the model in order to establish a good\r\nfit for the dataset under investigation.\r\nSeveral novel architectures are proposed for ISDSS based on existing distributed systems\r\ntechnologies. These architectures are assessed in terms of user interface, data and functional\r\nintegration. Implementation issues are also discussed.\r\nThe research contributions of this work are four-fold: (i) it lays the foundation for ISDSS\r\nas a distinct type of system for spatial decision support by examining the user interface,\r\nperformance and methodological requirements of such systems; (ii) it explores a new approach\r\nfor linking modelling techniques and SDSS; (iii) it investigates the possibility of modelling high\r\ntechnology industry; and (iv) it details novel architectures for ISDSS based on distributed\r\nsystems."^^<http://www.w3.org/2001/XMLSchema#string> .
