Principles and characteristics of main research methods.

No.	Methods	Principles	Characteristics
1	TODIM	By comparing any two solutions, the dominance matrix is constructed. The dominance of individuals is assembled to form the overall dominance, and the ranking is based on the dominance	The effect evaluation must be a specific value. It cannot evaluate the situation where the effect value is an interval value
2	MABAC	The border matrix is calculated based on the decision matrix. Then, the distance of each alternative from the border approximation area is used to rank the alternatives for selection	The computational process is simple, and the results are stable. It is easy to combine with other methods and does not reflect the decision maker's preference
3	TOPSIS	It is a sequential selection ranking technique of ideal similarity, which obtains the optimal selection by determining the solution with the shortest distance from the ideal solution and the farthest distance from the negative-ideal solution	It has the advantages of robust logical structure, simple computation, and considering both ideal and negative-ideal solutions. It is suitable for multiple attribute decision-making based on the full rationality of decision makers
4	VIKOR	A compromise ranking method that determines positive and negative-ideal solutions. It performs compromise ranking of finite decision alternatives by maximizing group utility and minimizing individual regret	With the characteristics of considering both group utility maximization and individual regret minimization and incorporating decision makers' subjective preferences, it has higher stability and credibility of the ranking
