The purpose of analyzing the subjective and objective factors affecting the timeliness of college English teaching is to develop corresponding strategies to enhance the timeliness of College English teaching. In this paper, an evaluation index system for the timeliness of college English teaching is constructed, and the basic process of fuzzy comprehensive evaluation method using fuzzy numerical analysis is designed. The optimal solution is found by comparing the corresponding objective function values after the bat position is updated, and the weights of the evaluation indexes are selected adaptively to ensure the objectivity of the index weights. In order to be able to more intuitively analyze the relevant factors affecting the timeliness of College English teaching, the questionnaire was used to obtain the evaluation index data, and numerical analysis was conducted for relevant and fuzzy comprehensive evaluation. The results show that the adaptive selection of indicator weights using the BA algorithm reaches the optimal convergence value of 0.504 after 10 iterations, and the weight of the evaluation indicators obtained at this point best reflects the distribution of English teaching effectiveness variables. The comprehensive evaluation score of the fuzzy numerical analysis carried out in College A is 2.1534, and the rating is in the middle, so its teaching content and methods need further improvement. The use of a fuzzy numerical combined evaluation index system can deeply excavate the relevant influencing factors of college English teaching timeliness, help college English teachers to innovate more effective teaching methods, and finally improve the timeliness of college English teaching.
