【摘要】：本论文根据相关质量管理体系中有关测量系统分析的要求,对测量系统分析的基本理论进行了系统的介绍,针对于M选煤厂生产过程中使用的测量系统,进行了测量系统的能力分析评价的工作。分析和讨论了测量系统分析的评价指标及算法,分别结合实际案例分别分析评价了计量型测量系统与属性型测量系统,并提出了相应的改善措施。其中,对计量型测量系统的检测能力分为三个水平——井下灰分、选煤厂灰分、精煤入仓口灰分进行了分析;对属性型测量系统的检测能力进行了样本和实验设计并进行分析。在论文数据处理方面,论文采用专业的质量分析软件Minitab,简化了数据分析方面的繁复的计算过程,大大减少了测量系统分析在企业中推广的障碍。本文对于煤质检测设备形成的计量型测量系统和以人为主形成的属性型测量系统的检测能力的分析评价的研究具有十分重要的理论意义和实践应用价值。论文主要研究内容及结论如下:(1)研究了选煤厂煤质测量系统或设备有效性保证方法,以及其他行业测量系统的能力评价或误差处理方法,并分析了这些方法的适用性;(2)研究了选煤厂中的测量系统分析的特点或者特殊性;(3)以M选煤厂为案例进行了分析,详细阐述了测量系统分析评价的详细实施步骤,并切实对该选煤厂的计量型和属性型测量系统的能力进行了评价分析。并得出结论计量型测量系统不可被接受;属性型测量系统识别出由3名检验员组成的测量系统的有效性亟需改进。(4)通过对计量型和属性型测量系统的评价结果分析,提出了改进测量系统的策略和方法,并且进行了前后对比,体现了测量分析的有效性。
[Abstract]:According to the requirement of measurement system analysis in relevant quality management system, this paper systematically introduces the basic theory of measurement system analysis, aiming at the measurement system used in the production process of M coal preparation plant. The evaluation index and algorithm of measurement system analysis are analyzed and discussed, and the metrological measurement system and attribute measurement system are analyzed and evaluated in combination with practical cases. And the corresponding improvement measures are put forward. Among them, the measuring ability of the metrological measurement system is divided into three levels-underground ash, coal preparation plant ash, ash content at the entrance of clean coal silo; The test ability of attribute measurement system is designed and analyzed. In the aspect of data processing, the paper uses Minitabs, a professional software for quality analysis, to simplify the complicated calculation process of data analysis. In this paper, the measuring ability of metering measurement system formed by coal quality testing equipment and attribute measurement system formed mainly by people is studied and evaluated. The main contents and conclusions of this paper are as follows: 1) the method of ensuring the effectiveness of coal quality measurement system or equipment in coal preparation plant is studied. And the capability evaluation or error handling methods of other measurement systems, and the applicability of these methods are analyzed. The characteristics or particularities of measurement system analysis in coal preparation plant are studied. The detailed implementation steps of the analysis and evaluation of the measurement system are described in detail, and the ability of the metrological and attribute measurement systems in the coal preparation plant is evaluated and analyzed, and the conclusion is drawn that the metrological measurement system is not acceptable. The effectiveness of the measurement system made up of three examiners needs to be improved urgently. Based on the analysis of the evaluation results of the metrological and attribute measurement systems, the strategies and methods of improving the measurement system are put forward. And the comparison before and after, which reflects the effectiveness of the measurement and analysis.
