Thesis (MSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Multi-criteria decision-making (MCDM) is a set of techniques designed specifically for the analysis
of complex problems. Geographical Information Systems (GIS) focus on spatial problem-solving
and spatial analysis. The integration of these methodologies offers a powerful approach to decision
making. Despite the fact that most spatial decision problems are multi-criteria problems by nature,
the process of MCDM is not well established or effectively integrated into the field of spatial
analysis and GIS.
This research focuses on bridging the gap between MCDM and GIS. To this end, a generic MCDM
extension was designed and implemented in ArcView. As a result, a first version MCDM extension
is offered. The extension expands ArcView's functionality with a limited set of MCDM methods.
This functionality is illustrated on two problems involved with developing the tourism potential at
Coutada 16 Wildlife Reserve in Mozambique.
The MCDM extension facilitates procedures that allow the evaluation of spatial problems and
includes the ability to deal with both raster and vector data. This system offers a generic problemsolving
environment, which can be used to evaluate geographical problems of any nature. This
research identifies a number of improvements to the developed functionality and successfully
illustrates the potential problem-solving capabilities associated with MCDM integrated with
ArcView. / AFRIKAANSE OPSOMMING: Multi Kriteria Besluitneming (MKBN) is n versameling metodes vir die analise van komplekse
probleme. Geografiese Inligtingstelsels (GIS) fokus op geografiese probleemoplossing en analise.
Die integrasie van hierdie twee metodologieë bied 'n kragtige benadering tot besluitneming. Ten
spyte daarvan dat die meeste geografiese probleme in wese meerveranderlik van aard is, is MKBN
nie effektiefbinne die raamwerk van GIS geïntegreer nie.
Hierdie studie fokus op die oorbrugging van die gaping tussen MKBN en GIS. Met hierdie doel
voor oë is 'n generiese MKBN-uitbreiding vir ArcView ontwerp en geïmplementeer. Die resultaat
is 'n eerste- weergawe MKBN-uitbreiding. Die uitbreiding brei ArcView se funksionaliteit uit om
'n beperkte versameling MKBN-metodes in te sluit. Die nuut ontwikkelde funksies word
geïllustreer aan die hand van twee probleme wat die ontwikkeling van die toerismepotensiaal vir die
Coutada 16 Wildreservaat in Mosambiek aanspreek.
Die uitbreiding maak voorsiening vir 'n MKBN-evaluasie van geografiese probleme en besit die
vermoë om beide vektor- en roosterdata te analiseer. Hierdie stelsel verskaf 'n generiese omgewing
vir probleemoplossing wat gebruik kan word om byna enige geografiese probleem te analiseer. Die
studie identifiseer verbeteringe op en uitbreidings van die ontwikkelde funksies en slaag daarin om
die potensiaal van probleemoplossing wat deur die integrasie van MKBN-tegnieke met ArcView
moontlik gemaak word, te illustreer.
