AHP method
Descriptions
Ease of use
It has high requirements for the level clarity of the model and the rationality of expert scoring. For complex systems, it is difficult to obtain a correct, clear, and complete hierarchical model at one time. It is difficult to find multiple field experts at one time. Therefore, the ease of use is not high.
Objectivity
It is a subjective weighting method with strong interpretability and objective calculation process, but the input data is highly subjective. Therefore, its objectivity is not high.
Versatility
It is generally applicable to various measurement and evaluation scenarios, so it has strong universality.
Functionality
Each measurement and evaluation operation can only measure a certain model or aspect, so its functionality is weak.
Costs
It is necessary to establish an evaluation hierarchy model and hire domain experts, which has high time and economic cost.
