提出一种基于模糊粗糙集属性约简理论构建能耗基线模型的方法。首先对初始的能耗影响因素进行模糊化并预处理,明确条件属性和决策属性,形成决策表;然后对决策表进行属性约简,获得与原能耗影响因素集合具有相同分类能力的能耗重大影响因素;最后将能耗重大影响因素作为输入变量构建能耗基线模型。中央空调系统节能改造项目能耗基线模型的算例可验证所提方法的有效性,并降低建模难度。
A method based on fuzzy rough set attribute reduction theory to construct the baseline model of energy consumption is proposed. Firstly, the initial energy consumption factors are fuzzified and preprocessed, and the condition attributes and decision attributes are defined to form the decision table. Then, the attribute reduction is performed on the decision table to obtain the energy consumption with the same classification ability as that of the original energy consumption influencing factor set Major influencing factors; Finally, the major energy consumption factors as input variables to build energy baseline model. The example of the energy consumption baseline model of the energy-saving renovation project of central air conditioning system can verify the effectiveness of the proposed method and reduce the difficulty of modeling.
