1. Expert scoring method
The expert scoring method is an evaluation method that appeared earlier and is widely used. It is based on quantitative and qualitative analysis and makes quantitative evaluation through scoring and other methods, and its results have mathematical statistical characteristics.
The main steps are:
First, select the evaluation indicators according to the specific conditions of the evaluation object, set an evaluation grade for each indicator, and the standard of each grade is represented by a score; Then based on this, experts analyze and evaluate the evaluation objects to determine the scores of each indicator; finally, the total score of each evaluation object is obtained using the additive scoring method, weighted scoring method, continuous multiplication scoring method or additive scoring method. value to obtain the evaluation result.
The biggest advantage of the expert evaluation method is that it can make quantitative valuations in the absence of sufficient statistical data and original data. The expert evaluation method is simple to use and highly intuitive.
The breadth and depth of experience and knowledge are extremely subjective, and its theoretical and systematic nature is not strong. Under normal circumstances, it is difficult to ensure the objectivity and accuracy of the evaluation results.
2. Analytical Hierarchy Process (AHP) The Analytical Hierarchy Process (AHP) was first proposed by American scholar T.L. Saaty in 1973. After years of development, it has become a relatively mature and qualitative method. Multi-criteria decision-making methods combined with quantitative analysis.
Advantages of AHP:
First of all, it effectively absorbs the results of qualitative analysis and gives full play to the advantages of quantitative analysis; it not only includes subjective logical judgment and analysis, but also relies on objective The precise calculation and deduction make the decision-making process highly organized and scientific. Secondly, AHP regards the problem as a system. The whole process embodies the systematic thinking mode of decomposition, judgment and synthesis, and also fully embodies the principle of dialectical system thinking.
Disadvantages of AHP:
(1) In application, the randomness in the evaluation process and the subjective uncertainty and cognitive ambiguity of evaluation experts cannot be escaped.
(2) And the judgment matrix is ??prone to serious inconsistencies.
(3) The result obtained by the AHP method is a rough ranking of solutions.
