统计过程控制(SPC)在烟叶打叶复烤生产过程中的应用(任务书,开题报告,论文37000字,小论文1900字)
摘 要
经济全球化的迅猛发展推动和激励了现代制造企业质量管理体系的建立和不断完善。现代企业管理中,全面质量管理TQM越来越受到企业高层领导的重视。质量管理的信息化技术应用,也是企业提高产品质量,开拓营销市场的有效手段。工序过程质量控制是质量管理的重要一环,是质量控制的核心内容。我国烟叶打叶复烤行业的硬件水平与发达国家相比差距并不明显,但在质量管理,尤其是工序过程质量控制上差距较大。目前,我国大部分烟叶打叶复烤企业仍处于质量检验阶段,工序过程质量控制的手段、方法较为薄弱。统计过程控制(SPC)技术的应用是对工序质量控制的一套良好的方法,因此对基于统计过程控制(SPC)的质量管理体系进行研究与应用具有强烈的现实意义。
本文首先阐述了SPC技术在打叶复烤行业的应用历史、优势及现状,从而提出了本论文的研究目的和意义。然后,结合实际情况及对相关文献的检索,对SPC技术的理论原理进行了基本的说明。并具体描述了烟叶打叶复烤生产工艺知识及各工序的质量要求。最后,结合SPC原理和打叶复烤的生产状况,选定关键工序和关键参数在生产过程中的管理规格。综合实际条件选出了适合的抽样管理方法。通过一段时间的实践管理过程的运用,对发生的各项问题的进行分析及改善,验证了方法的可行性,并将SPC技术在全公司进行推广。

ABSTRACT
The rapid development of economic globalization promotes and encourages the construction and constant perfection of quality management system in the modern manufacturing enterprise. In the modern enterprise management, corporate executives pay more and more attention to TQM. Information technology applications of Quality
management are effective means for enhencing the quality of the products and developping the market. As an important part of quality management, Process quality control is also the core content. Comparing with the developed countries, there isn't obvious gab in hardwares in China's leaf tobacco threshing and redrying industry, but there is a significant gap in quality management, especially in process quality control.At present, most of the leaf tobacco threshing and redrying industry is still in the testing phase of quality, the means and methods of process quality control are weak. Statistical Process Control (SPC) System is a good process quality control method, therefore, the research and application of quality management system based on statistical process control (SPC) are strong practical significance.
This article describes the application history of SPC technology in the leaf tobacco threshing and redrying industry,advantages and status, which made the purpose of this research and the significance.Then, with the actual situation and the retrieval of relevant literature on the theoretical principle of SPC technology basic instructions.And specifically describes the process of knowledge production and the leaf tobacco threshing and redrying process quality requirements.Finally, the production of SPC principles and the leaf tobacco threshing and redrying status, selected key processes and key parameters in the production process management specifications.Selected for the actual conditions of comprehensive sampling management.Through a period of practical application of the management process, the questions that occur to analyze and improve the feasibility of the method was verified, and SPC in the whole company promotion.
