【摘要】 随着计量行业的发展及国务院提出的《计量发展规划2021-2035》,国家对计量工作提出了建成科技水平一流、符合时代和国际发展潮流的测量体系等新要求。各计量技术机构及企业计量管理部门为响应此项要求对测量管理体系进行的更新与完善,成为下阶段工作中的重点。一方面传统计量工作对于测量设备的分级管理,仅以强制检定设备范围及测量设备是否有量值为划分依据,测量人员不能从设备分级中获取足够信息,容易导致使用人员因相关信息不足将测量设备在测试过程中超预期使用,不能得到准确结果。另一方面,计量工作对测量设备校准周期的制定与调整尚未构成统一的标准,目前校准周期的制定主要依据校准规范建议的复校周期,校准周期的动态调整则参考CNAS-TRL-004中建议的经验和长期趋势做出的简单反应调整法,缺乏成本考量及可操作性。为解决上述问题,本文在现有测量管理体系中逐层分析探寻薄弱环节,通过对环节中存在的问题从根源进行剖析,针对问题点引入业内先进管理工具,达到测量管理体系优化改进的目的。本文以T公司计量室对测量设备的管理作为研究对象,研究T公司对测量设备的分级管理及校准周期的制定与动态调整。首先,在测量设备的分级管理中,T公司计量室在传统ABC划分基础上对划分方式重新作出调整,运用加权评分法分别从资产净值、精度评级、偏离失效概率、关键程度四个方面进行评估,将四方面评分汇总后的综合评分作为测量设备ABC划分的依据,为后续评估分析打下基础。其次,在校准周期动态调整方面,运用测量系统分析对测量设备实际运行情况进行整体评估。最后,将测量设备评估结果结合田口质量工程学对测量设备的校准周期进行动态调整,达成费用与校准风险的平衡。本文研究有助于提高T公司测量设备控制管理,将质量工具应用于计量工作中。使测量设备的级别划分更具理论依据,评价维度更加多元,综合评价更加系统;测量设备的校准周期制定与动态调整结合设备本身运行状况,为后续其他类型设备的周期管理提供参照。更多还原

【Abstract】 With the development of the metrology industry and the Metrology Development Plan 2021-2035 proposed by the State Council,the country has put forward new requirements for metrology work,such as building a measurement system with firstclass scientific and technological level that conforms to the times and international development trends.The updating and improvement of the measurement management system by various measurement technology institutions and enterprise measurement management departments in response to this requirement has become the focus of work in the next stage.On the one hand,the classification management of measuring equipment in the traditional measurement work is only based on the scope of the mandatory verification equipment and whether the measuring equipment has a measurement value.The measuring personnel cannot obtain enough information from the equipment classification,which may easily lead to the use of the measuring equipment in the test process beyond expectations due to insufficient relevant information,and can not obtain accurate results.On the other hand,the measurement work has not yet formed a unified standard for the formulation and adjustment of the calibration intervals of measuring equipment.At present,the formulation of the calibration intervals is mainly based on the recalibration intervals recommended by the calibration specification.The dynamic adjustment of the calibration intervals refers to the experience recommended in CNAS-TRL-004 and the simple response adjustment method made by long-term trend,lacking cost consideration and operability.In order to solve the above problems,this thesis analyzes and explores the weak links layer by layer in the existing measurement management system,analyzes the root causes of the problems in the links,and introduces advanced management tools in the industry to solve the problems,so as to optimize and improve the measurement management system.This paper takes the management of measuring equipment in the measurement room of Company T as the research object,and studies the hierarchical management of measuring equipment and the formulation and dynamic adjustment of calibration intervals in Company T.First of all,in the hierarchical management of measuring equipment,the measurement room of Company T readjusted the classification method on the basis of traditional ABC classification,and used the weighted scoring method to evaluate the measurement equipment from four aspects:net asset value,accuracy rating,probability of deviation from failure,and criticality.The comprehensive score after the summary of the scores from all sides was used as the basis for ABC classification of measuring equipment,laying a foundation for subsequent evaluation and analysis.Secondly,in the dynamic adjustment of the calibration intervals,the actual operation of the measuring equipment is evaluated as a whole using the measurement system analysis.Finally,combining the evaluation results of measuring equipment with Taguchi Quality Engineering,the calibration intervals of measuring equipment is dynamically adjusted to achieve a balance between cost and calibration risk.This thesis will help to improve the control and management of measuring equipment in Company T,and apply quality tools to measurement work.Make the level division of measuring equipment more theoretical,the evaluation dimensions more diversified,and the comprehensive evaluation more systematic;Make the calibration intervals formulation and dynamic adjustment of measuring equipment more integrated with the equipment itself,and provide reference for subsequent intervals management of other types of equipment.更多还原
