Questionnaire regarding flood control alternative

Dear Sir/Madam:

Thank you very much for taking the time to fill out this survey questionnaire. The purpose of this questionnaire is to evaluate four alternatives with four attributes about flood control alternative. This survey is conducted anonymously, and the results are only used for research purposes in the paper. Thank you again for your support!

Tips: Your evaluation is expressed by probabilistic linguistic term sets (PLTSs), the linguistic terms are “very poor”, “slightly poor”, “fair”, “good”, “very good”. The PLTS {fair (0.5), good (0.3), very good (0.2)} means that you are 50% sure that it is fair, 30% sure that it is good, and 20% sure that it is very good.
