Note: It is not just one algorithm in the whole article, use one algorithm to solve a small part of the problem, and use other algorithms in other places.
1. Analytic Hierarchy Process
How to build a hierarchical model: (solve qualitative problems quantitatively)
Top level: The purpose of the decision, the problem to be solved.
Bottom layer: Alternatives when making decisions.
Middle layer: factors to consider, criteria for decision-making.
The target layer, the criterion layer, and the program layer.
Routine: In terms of expression: (After searching a large amount of data and synthesizing expert opinions in related fields, I constructed...)
Pairwise comparison matrix: indicates the comparison of the relative importance of all factors in this layer to a certain factor in the previous layer.
(1) Inconsistency is allowed, but the scope of inconsistency must be determined .
(2) Construct a pairwise comparison matrix. [importance of factors to other elements] ( sometimes strongly subjective )
