    Application of analytical hierarchy process (AHP) for parameter identification in environmental resource modelling
    (2010) Sooriyabandara, NN; Wijesekera, NTS
    Use of Geographic information System (GIS) to determine the spatial availability of environmental resources is a very versatile method in any present level of practice. In this context, identification of environmental resources with respect to its potential becomes critical Properly aggregated resources, together with the spatial variation will be a meaningful representation of its slams for practical purposes. Therefore, an appropriate methodology to determine an aggregated weightage for environmental resources is critical AHP is one of the such tools, which is most commonly used in determining an aggregate value, based upon its parameters and parameter classes. Present study examines the spatial availability of dynamic environmental resources for conservation purposes together using GIS and AHP.

    Spatial Prioritization of Infrastructure Management Using Stakeholder Experience
    (2010) Sooriyabandara, NN; Wijesekera, NTS
    Polarization of available infrastructures is an essential requirement for sustainable management of resources in infrastructure management. The use of geographical information system (GIS) provides as opportunity to execute the said requirement by considering the need of immediate attention and special existence of the infrastructures. GIS models with AHP provide manner, thus, enlightening the prioritization requirements. Computation of the weight in AHP is subjective and judgmental, thus the prioritization of resources can be varied while sustaining the mathematical requirements of AHP calculations. The present study demonstrate the use of stakeholder's option in assigning weighted factors and the application of AHP in prioritization of spatially varied infrastructure in GIS environment to achieve better management options.
