When multiple experts perform AHP analysis, the judgment matrices from each expert need to be processed using the "Geometric Mean" (not arithmetic mean).

Formula: Geometric Mean = (a₁ × a₂ × ... × aₙ)^(1/n)

Where n represents the number of experts, and a₁, a₂, ..., aₙ represent the judgment values at the corresponding positions from each expert.

The geometric mean of multi-expert judgment matrices is used to obtain a consolidated judgment matrix.
