摘　　要：针对现有机械供暖系统的节能运行效果评价方法单一、供暖设备在实际运行中节能运行效果无法评价等问题,提出基于模糊算法的机械供暖系统节能运行效果评价方法。该方法依据机械供暖系统的运行原理选取安全、工艺和能效为评价指标并构建适宜评价指标体系,采用模糊算法构建供暖系统节能运行效果的评价体系模型,确定节能运行效果的评价因素集、等级与权重,基于确定的模糊矩阵与权重向量模糊合成二级指标,结合最大隶属度原则与模糊综合评价向量为不同等级分配权重向量,令机械供暖系统节能运行状态获取综合评价值作出决策。实验结果表明,该方法可有效评价机械供暖系统节能运行效果,防御性能较好,有助于提高机械供暖系统节能运行效果评价能力,为后续机械供暖系统的实际发展与建设提供合理化建议。Aiming at the problems that the existing evaluation method of energy-saving operation effect of mechanical heating system is single and the energy-saving operation effect of heating equipment can not be evaluated in actual operation,an energy-saving operation effect evaluation method of mechanical heating system based on fuzzy algorithm is proposed.According to the operation principle of mechanical heating system,safety,process and energy efficiency are selected as evaluation indexes and a suitable evaluation index system is constructed.The evaluation system model of energy-saving operation effect of heating system is constructed by using fuzzy algorithm,and the evaluation factor set,grade and weight of energy-saving operation effect are determined.Based on the determined fuzzy matrix and weight vector,the secondary index is fuzzy synthesized.Then,combining the principle of maximum membership degree and fuzzy comprehensive evaluation vector,the weight vector is allocated for different levels,so that the energysaving operation state of mechanical heating system can obtain the comprehensive evaluation value and make a decision.The experimental results show that this method can effectively evaluate the energy-saving operation effect and defense performance of mechanical heating system,helping to improve the evaluation ability of energy-saving operation effect of mechanical heating system,and provide reasonable suggestions for the actual development and construction of subsequent mechanical heating system.
