1. A method of carbon sequestration and storage site selection, the method comprising:
obtaining range estimations of a plurality of criteria for a plurality of potential carbon sequestration and storage sites;
selecting random criteria values in respective range estimations for the plurality of criteria for the plurality of potential carbon sequestration and storage sites;
forming a decision matrix from the random criteria values;
determining a plurality of criteria weights, wherein the determining the plurality of criteria weights comprises:
obtaining, from at least one evaluator, a plurality of pairwise relative comparisons of the plurality of criteria;
generating a weight matrix based on the plurality of pairwise relative comparisons; and
determining an eigenvector for the weight matrix;
weighing the decision matrix according to the plurality of criteria weights, wherein a plurality of potential carbon sequestration and storage site representative vectors are obtained;
scoring at least some the plurality of potential carbon sequestration and storage sites according to similarities of respective potential carbon sequestration and storage site representative vectors, of the plurality of potential carbon sequestration and storage site representative vectors, to a best vector and to a worst vector, wherein a set of scores for the potential carbon sequestration and storage sites are obtained;
ranking the potential carbon sequestration and storage sites according to the set of scores;
repeating the selecting, forming, weighing, scoring, and ranking a plurality of times, wherein a plurality of sets of scores and a plurality of rankings are obtained;
displaying a visualization of the plurality of rankings;
selecting a carbon sequestration and storage site from among the plurality of potential carbon sequestration and storage sites based on the visualization; and
sequestering and storing carbon at the carbon sequestration and storage site based on the selection.
