TOPSIS | According to the approaching degree of limited evaluation objects and idealized goals, the relative merits of existing objects are evaluated. | Making full use of the original information, the results are likely to be consistent with reality; is able to sort out the merits and faults of each evaluation object. | Low sensitivity | Zhang, X.L. [38] |
AHP | This refers to the decision-making method which decomposes the elements related to the decision in regard to goals, criteria, schemes, and so on, and facilitates qualitative and quantitative analysis on this basis. | Systematic; results are simple and clear; less quantitative data needed | There are less quantitative data, more qualitative components, and is less convincing. | Yang, Y.F. [39] |
FCE | According to the membership degree theory of fuzzy mathematics, qualitative evaluation is transformed into quantitative evaluation—that is, fuzzy mathematics makes an overall evaluation of things or objects restricted by various factors. | Good for solving fuzzy and difficult problems; is also suitable for solving various non-deterministic problems; strong systematicness. | Evaluation subjectivity is obvious, and the evaluation results are not comprehensive enough | Ma, L.; Liu, X.G.; Liu, Z.W. [40] |
Synthetical Index | This is done through the comparison of two comprehensive total amounts to comprehensively reflect the total change degree of multiple individuals. | The evaluation process is systematic and comprehensive, the calculation is simple, and the data can be fully utilized. | The original data needs to be complete and the reliance on comparative standards is too strong; evaluation result lacks certain intuition | Wang, Y.Z.; Zhou, Y.Y.; Deng, X.Y. [41] |
Content Analysis | Non-quantitative literature materials are converted into quantitative data, the content of the literature is quantitatively analyzed, and judgement and inference about the facts are made according to these data. | Systematic, objective, and quantitative | The classification and the operation is complicated | Zhou, G.H.; Singh, J.; Wu, J.C.; Sinha, R.; Laurenti, R.; Frostell, B. [29] |
