Under the condition that the number of decision makers in each scheme to be evaluated is unequal, a multi-level and multi-attribute fuzzy comprehensive group decision-making model is established. On the basis of focusing on the investigation of 24 competition questions in previous national college students' mathematical modeling competitions, the model is applied to comprehensively evaluate these competition questions, and the evaluation results verify the effectiveness and feasibility of the model.
The National Mathematical Modeling Competition for College Students was founded in 1992 and held once a year. It has become the largest basic subject competition in domestic universities and the largest mathematical modeling competition in the world.
In 20 18, 1449 colleges/campuses and 42 128 teams (38,573 undergraduate teams and 3,555 junior college teams) from 34 provinces/cities/regions (including Hongkong, Macau and Taiwan Province) and the United States and Singapore signed up for the competition.
