摘要:With the continuous advancement of the “Double First-Class” university plan, the status and role of experimental teaching in university teaching has become increasingly prominent. Chosen as one of the “Double First-Class” universities, Beijing Institute of Technology has also carried out a series of experimental teaching reforms, and has produced different reform plans in the laboratory of “Geometrical Accuracy Specifications”, School of Mechanical Engineering. In order to optimize different schemes, the experimental teaching center innovatively proposes an optimized model improved by clear theory. This is a decisionmaking method based on triangular fuzzy number and clear theory. Utilizing the fuzzy theory and clear theory, the advantages and disadvantages of the alternatives can be ranked more accurately, the influence of subjective and objective factors in the process of selecting the alternatives can be reduced, and new methods can be provided for decision makers to choose the best alternative.
