Analytical hierarchical / network process (AHP/ANP) allows for the exploration of how risks are perceived by individuals, through quantifying the relative importance of the different projections of risk, impacts and opportunities in conjunction with exploration of other factors that may affect business resilience. AHP / ANP can provide different estimates of risk and opportunities based on users weighting of the criteria. The method can be employed to provide data for elements of the strengths, weakness, opportunities and threats (SWOT) framework; it can provide more provide quantitative evaluation of risk and opportunities (ANP provides relative values, not absolute values).
The strength of this type of approach is users weighting the relative importance of different risk / opportunity theme and data as well as weight the severity or impact values provided by GIS based impact layers. Non spatial based sub models for the strengths and weaknesses SWOT elements are included to address more qualitative and institutional issues of climate change preparedness and adaptive capacity.
