基于模糊层次分析法的设备状态系统量化评价新方法

摘要:设备因结构形式多样、耦合复杂、功能多元化、运行参数多等因素难以进行系统状态评价,论文在分析了设备系统功能层次结构特点基础上,运用模糊综合评价和层次分析法,提出了一种系统量化评价设备状态的方法.考虑到设备运行过程中各参数的'影响,研究了设备状态及其评价层次模型,采用健康值来综合测度设备运行状态;运用层次分析法结合专家经验,研究了评价层级结构权重;采用模糊综合评价理论研究了正负指标的隶属函数构建方法,探讨了系统评价矩阵和模糊变换算子,并建立了基于模糊层次分析法的设备状态系统评价模型,计算出各子系统的健康值,以量化评价设备系统状态,从而全面掌握其系统状态.运用该方法在水泥行业中的回转窑设备进行评价分析,验证了其有效性.Abstract:It is very difficult to carry out system evaluation for equipment state due to the structural multiplicity, the coupling complexity, the functional diversification and the excessive operating parameters factors, this article analyzes the structural features of equipment, a quantitative evaluation method of equipment state is developed using fuzzy synthesis evaluation and analytic hierarchy process methodology. Considering the impact of various parameters in the process of equipment running, the equipment state and its evaluation hierarchy model are analyzed. The health value is employed to quantitatively describe the running state degree of equipment. The weight vectors of all evaluation hierarchies axe discussed by using the analytic hierarchy process methodology with the experiences of expert. Applied the fuzzy set evaluation theory, a type of subjection function of positive and negative indicators is developed, and the evaluation matrix is discussed as well as fuzzy transformation algorithm operators. The valuation model for equipments health state based on fuzzy and analytic hierarchy process is built. Therefore, the health value of subsystems can be gotten to quantify the evaluation of equipment system state, that is also the state of equipment is clear, which provides us with theoretical guide for seeking further optimization maintenance strategy. Finally, an application of the method in rotary kiln used in cement industry verifies its effectiveness. 作者: 宾光富[1]  李学军[2]  DHILLON Balbir-S[3]  楚万文[4] Author: BIN Guang-fu[1]  LI Xue-jun[2]  DHILLON Balbir-S[3]  CHU Wan-wen[4] 作者单位: 湖南科技大学,机械设备健康维护湖南省重点实验室,湘潭,411201;Department of Mechanical Engineering,University of Ottawa,Ottawa K1B 6N5湖南科技大学,机械设备健康维护湖南省重点实验室,湘潭,411201;清华大学,精密仪器与机械学系,北京,100084Department of Mechanical Engineering, University of Ottawa, Ottawa K1B 6N5湖南科技大学,机械设备健康维护湖南省重点实验室,湘潭,411201 期 刊: 系统工程理论与实践   ISTICEIPKU Journal: SYSTEMS ENGINEERING--THEORY & PRACTICE 年,卷(期): 2010, 30(4) 分类号: B114.3 TH17 关键词: 模糊层次分析法    设备状态    健康值    量化评价    Keywords: fuzzy and analytic hierarchy process    equipment state    health state    quantitative evaluation    机标分类号: TP2 S15 机标关键词: 模糊层次分析法    设备状态    状态系统    量化评价    评价新方法    the analytic hierarchy process    fuzzy    evaluation method    系统状态评价    模糊综合评价    quantitative evaluation    operating parameters    structural features    设备系统    valuation model    cement industry    transformation    running    系统评价模型    评价理论研究 基金项目: 国家高技术研究发展计划(863计划),教育部新世纪优秀人才支持计划,湖南省教育厅资助项目 基于模糊层次分析法的设备状态系统量化评价新方法[期刊论文]  系统工程理论与实践 --2010, 30(4)宾光富  李学军  DHILLON Balbir-S  楚万文设备因结构形式多样、耦合复杂、功能多元化、运行参数多等因素难以进行系统状态评价,论文在分析了设备系统功能层次结构特点基础上,运用模糊综合评价和层次分析法,提出了一种系统量化评价设备状态的方法.考虑到设备运行过...
