Evaluating Product Scheme Method Based on QFD and Euclid Norm [PDF]

, 2011
为建立面向顾客满意的贯穿产品全生命周期的方案评价模型,对传统质量功能配置进行了改进,实现了产品全生命周期的瀑布式分解.由于方案中属性权重的确定对后续评价起着至关重要的作用,利用I-Qfd-E(IMPrOVEd QuAlITyfunCTIOn dEPlOyMEnT And EnTrOPy)方法获取指标权重值,达到了主客观相结合的目的.由于备选方案存在模糊性,所以采用模糊理论中的欧氏范数对备选方案进行排序.实例结果表明,基于I-Qfd-E和欧氏范数的产品方案评价方法能够得到面向顾客满意的最优方案.In ...

基于物元分析法的电力变压器套管健康状态评估

Gaoya dianqi, 2015
套管故障率往往高于变压器本体,准确评估套管健康状态对提高变压器整体运行可靠性十分重要。文中基于物元分析理论提出了套管健康状态的评估方法。以试验检测数据为基础,综合考虑巡视检查与维护历史状态参量,构建了套管健康状态评估的层次型指标体系;采用层次分析法（AHP法）确定指标初始权重,并根据指标数据变化量、利用信息熵对试验类指标的初始权重进行修正。基于物元理论构建了套管健康状态的评估物元,考虑到定量指标测量干扰及定性指标主观判断所带来的误差,采用一个数据区间来表征指标状态 ...

基于改进TOPSIS法的变电站智能装备巡检点评价方法研究

Gaoya dianqi
当前变电站智能巡检装备如机器人、无人机的巡检点主要由人工经验性地预设，耗时耗力且巡检质量难以保证，为实现变电站高智能、高质量、高效率巡检，提出一种智能巡检装备巡检点生成质量的评价方法。首先针对变电站智能装备拍摄质量、光照契合度和巡检效率提出了一种基于拍摄势模型的巡检点自动布设方法。然后提出了基于改进TOPSIS法的综合评价方法，通过层次分析法和熵权法确定指标的综合权重，根据各方案与理想方案的贴近度确定最优方案。最后在国内某变电站进行了实例计算，结果表明基于拍摄势模型的机器人 ...
