摘　　要：常规的数学建模方法在建筑物化阶段难以准确测算边界结构,为准确模拟CO_(2)减排量计算结果,使用DEA算法,建模分析建筑物化阶段CO_(2)减排量。获取建筑材料加工运输以及使用阶段具体减排参数,设定DEA数学模型测算边界,分别计算其时间边界与空间边界,构建DEA数学模型总体框架,计算建筑物化阶段CO_(2)减排总量,实现建筑物化阶段CO_(2)减排量的数学建模。实验结果显示,该数学模型在现场浇筑与直接装配的工程中,均能得到更准确的模拟结果,模型应用误差更小,CO_(2)减排量计算结果的准确性得到优化。The conventional mathematical modeling method is difficult to accurately calculate the boundary structure in the construction stage.In order to accurately simulate the calculation results of CO_(2) emission reduction,DEA algorithm is used to model and analyze the CO_(2) emission reduction in the construction stage.The study obtains the specific emission reduction parameters of building materials processing,transportation and use stage and sets the calculation boundary of DEA mathematical model.It calculates its time boundary and space boundary,build the overall framework of DEA mathematical model,calculates the total amount of CO_(2) emission reduction in the building stage,and realize the mathematical modeling of CO_(2) emission reduction in the building stage.The experimental results show that the mathematical model can get more accurate simulation results in the field pouring and direct assembly projects,the application error of the model is smaller,and the accuracy of CO_(2) emission reduction calculation results is optimized.
