Quality Risk Evaluation of Urban Rail Transit Construction Based on AHP–FCE Method

Table 1

Evaluation methods.

No.	Methods	Advantages	Disadvantages
1	Gray relational analysis	Easy to use, does not require a lot of sample data, and is suitable for filling gaps due to missing data	Subjective and difficult to determine the optimum value for some of the indicator data
2	TOPSIS	Objective and realistic reflection of reality and is intuitive and reliable	Specific data are needed for each evaluation indicator. Selection of quantitative indicators is difficult
3	Analytic hierarchy process (AHP)	Method is simple, and a small amount of quantitative data involved makes it a more systematic analysis method	Much subjective qualitative analysis and little objective quantitative data. Amount of data collation, statistics, and arithmetic makes solutions for decision-makers difficult
4	Fuzzy comprehensive evaluation (FCE)	Results of evaluation calculations are presented in vector form, which is rich in the information contained	Complex calculation process. Susceptible to subjective components in determining weights of vector indicators
