Construction environment and energy application engineering is a major with strong engineering applicability, which mainly trains students to be able to engage in industrial and civil construction environment control and energy supply. According to the requirements of engineering certification, the graduation requirements of construction environment major control index points each factor should be calculated according to the training objectives and Curriculum system. At present, due to the short time of engineering certification in our country, professional teachers still lack the knowledge, understanding and grasp of the calculation method of relevant weight coefficient, which is not conducive to the development of teaching under the goal of professional engineering certification, and does not meet the professional development requirements of engineering certification. On the basis of engineering certification standard, this paper analyzes the relationship between graduation requirement index points and supporting courses of Jianhuan major. By using AHP, the judgment matrix of index points and supporting courses is established, and the weight coefficients of each index point factor are calculated and analyzed, and the weight coefficients of different index points of graduation requirement are obtained At the same time, the weight coefficient obtained by AHP is compared with that obtained by credit method, and the advantages and disadvantages of each calculation method are pointed out, in order to promote the engineering certification of construction and environmental protection specialty.the construction environment and energy application engineering is a major with strong engineering applicability, which aims to train students to be able to engage in industrial and civil construction environment control and energy supply. According to the requirements of engineering certification, the graduation requirements of the construction environment major should control all factors of the index points according to the training objectives and curriculum system to calculate the weight coefficient. At present, due to the short time of engineering certification in our country, professional teachers still lack the knowledge, understanding and grasp of the calculation method of relevant weight coefficient, which is not conducive to the development of teaching under the goal of professional engineering certification, and does not meet the professional development requirements of engineering certification. Based on the engineering certification standard, this paper analyzes the graduation requirements index points and their factors of the major of constructi030.03.662on and environment, establishes the judgment matrix by using the analytic hierarchy process, and calculates and analyzes the weight coefficients of the factors of each index point, and obtains the weight coefficients of different index points of graduation requirements The calculation results are analyzed and discussed in order to promote the engineering certification of the construction and environmental protection specialty.
