摘要
为了对区域能源效率做出客观评价,提出一种新的基于不可控因素的地级城市分类的能源效率分类比较方法,旨在研究能源效率的地区可比性问题。分类问题的讨论包括类别个数的确定和分类方法的选取;分类个数和分类原则的确定采用预测强度和基础因子相结合的办法,进一步采用k最近邻分类方法对其余不可控因子进行分类预测,以避免所谓的自评判问题;运用文中所给出的综合分类结果对一些城市的能源效率进行评价,便于相关城市找到提高能源效率的有效措施。"
This paper presents a novel method based on uncontrollable factors cities classify energy efficiency classification comparison method to study the issue of energy efficiency comparable areas in order to make an objective evaluation of regional energy efficiency. Classification issues discussed include the identification and classification of the selected category number. Classification to determine the number and classification principles and basic factors prediction strength combined approach to further the use of k-nearest neighbors classification method to classify the remaining non-controllable factors to predict, in order to avoid the so-called self-evaluation questions. Finally, the use of comprehensive classification given in the text of some of the city＇s energy efficiency evaluation, easy to find effective measures related to the city to improve energy efficiency.
