(1) Define the unstructured problem and state clearly the objectives and outcomes.
(2) Decompose the complex problem into a hierarchical structure with decision
elements (criteria and alternatives).
(3) Employ pairwise comparisons among decision elements and form comparison
matrices.
(4) Use the eigenvalue method to estimate the relative weights of the decision
elements.
(5) Check the consistency property of matrices to ensure the judgments of decision
makers are consistent.
(6) Aggregate the relative weights of decision elements to obtain an overall rating
for the decision alternatives.
