【摘要】：从19世纪末工业革命前的传统质量管理发展到现在的精益六西格玛质量管理,质量管理经历了漫长的发展历程,而它的范围也从关注产品本身逐步扩展到基于客户驱动的产品质量管理模式。而对于众多的企业而言如何合理并且充分的利用这些研究成果不仅仅是质量体系的建立,更重要的是如何使其能够和自己的实际情况相结合发挥各种管理理论和工具方法的最大效果。本文通过PC公司立式烘包机产品开发过程中的质量管理为背景,分析了现在公司的产品开发流程和质量管理的方法,通过对现有产品的数据分析提出现在的产品开发质量管理中存在的问题。再进一步与相关的质量管理理论进行对比,提出了基于质量功能展开QFD(Quality Function Deployment)和设计失效模式及影响分析dfmea(designfailuremodelandeffectsanalysis)模型的质量控制方法。pc公司在开发前端由于缺少对于客户需求的充分收集和分析因此设计出的产品缺乏针对性,对于客户关注的质量需求未给予足够的重视,使最终的产品客户满意度较差。因此论文提出采用质量功能展开的来改善以上问题,通过建立自己的qdf流程采用多种途径来获取客户需求将其转化为产品的质量特性,通过质量规划来分析产品的市场竞争性、设定产品卖点来获取市场优势。再通过技术竞争能力评估来分析出影响客户需求的重点质量特性,采用设定合理的目标值利用优势资源来重点满足,使产品能够在技术上取得领先,让客户体验到高质量的产品。在设计阶段通过研究过去的产品数据发现由于设计阶段缺乏具有针对性的失效分析和测试,致使部分产品存在严重的质量缺陷造成了客户的投诉。所以引入了dfmea作为控制工具,建立新的设计控制流程,以建立可靠性方框图为基础来分析整个机器的部件、子系统和全系统,通过对于各种可能出现的失效形式进行充分的评估并计算RPN(Risk Priority Number),对于高风险的项目均采取相应的预防措施如修改设计、加强测试等。尤其对于在QFD中分析获得的关键质量特性给予高度关注,这些项目即使RPN数值在合理范围内我们仍然对其做了进一步的改进和测试,使产品的质量进一步提高。在立式烘包机产品开发过程中应用质量功能展开和设计失效模式及影响分析虽然遇到一定的困难,因为新的流程和工具的引入增加了相关部门的工作量,但是由于得到领导层的大力支持仍然顺利的完成了这款产品,在投入市场后得到了客户的一致认可,有力的扭转了公司在市场上的竞争地位,甚至有海外客户也来询价和购买样机。
[Abstract]:From the traditional quality management before the end of the nineteenth Century industrial revolution to the present Lean Six Sigma quality management, quality management has experienced a long course of development, and its scope has been gradually expanded from the product itself to the customer driven product quality management model. Using these research results is not only the establishment of the quality system, but also how to make it possible to combine the actual situation with its own situation to maximize the effect of various management theories and tools. This paper analyzes the current product development flow of the company through the quality management of the product development process of the vertical bake machine in PC company. The method of process and quality management, through the analysis of the data of existing products, put forward the existing problems in the quality management of product development, and then compared with the related quality management theory, and put forward the QFD (Quality Function Deployment) based on the quality function and the design failure mode and the impact analysis DFMEA (designfailuremo). Delandeffectsanalysis) the quality control method of the model.Pc company in the development front end due to the lack of full collection and analysis of customer needs, the design product is lack of pertinence, not enough attention is given to the quality needs of the customer, and the final product customer satisfaction is poor. Therefore, the paper proposes the use of quality work. In order to improve the above problems, we can use a variety of ways to obtain customer requirements by establishing their own qdf process to transform them into product quality characteristics, analyze the market competitiveness of products through quality planning, set product selling points to obtain market advantages, and then analyze the impact of customer needs through the evaluation of technical competitiveness. Key quality characteristics, using a reasonable target value to focus on the use of the advantage resources to make the product be able to take the lead in technology and let the customer experience high quality products. In the design phase, through the study of past product data, there is a lack of needle pair failure analysis and testing in the design phase, resulting in the existence of some products. DFMEA is introduced as a control tool to establish a new design control process, based on the establishment of a reliability block diagram to analyze the components, subsystems and whole systems of the whole machine, and to fully evaluate and calculate RPN (Risk Priorit) by various forms of failure. Y Number) take appropriate precautions for high risk projects, such as modifying the design, strengthening the test, and so on. Especially for the key quality characteristics obtained in the QFD, these projects further improve and test the quality of the project even if the RPN value is in a reasonable range, so that the quality of the product is further improved. The application of quality function expansion and design failure mode and impact analysis in the development process of vertical bake machine encountered certain difficulties, because the introduction of new processes and tools increased the workload of the relevant departments. However, because of the strong support from the leadership, the product was completed smoothly and after the market was put into the market. The unanimous recognition of customers has effectively reversed the company's competitive position in the market, and even overseas customers have come to inquire and buy prototypes.
