【摘要】：近年来,随着铁路机车制造业的大发展,机车产品质量的提升也越来越受到关注。做好一个市场,巩固一个市场,重要的是产品的质量。产品的质量关系着公司的生存和发展。如何在有竞争力的价格优势下,生产高质量的机车产品,用质量占领市场,巩固市场,是机车生产企业坚持不懈努力的方向。最早的机车制造业均是“自己自足”的生产模式,除了原材料外,大部分零部件均是由自己公司生产。而现在的机车制造业,从“做专做精”的角度出发,重在机车的设计、关键零部件的生产、整车组装外,其他的大部分零部件均是外购。外购件的产品质量对机车的质量起着至关重要的作用。供应商的产品质量也是企业研发和生产质量的组成部分,供应商的质量管理体系逐渐成为企业的质量管理体系。本文作者以提升外购件质量的方法为研究载体,从企业情况、销售环境、外购件采购情况入手,通过对外购件供应商管理、采购、检验、储存、质量直接控制手段的分析,发现公司在外购件质量控制存在着质量控制策划、外购件质量数据、供应商体系管控、库存管理等四个方面的问题,提出供应商质量控制坚持五项基本原则、实施内燃机车外购件质量控制项目管理、供应商开发和选择评价策略、供应商质量培育策略、关键重要件质量控制手段策略、外购件的贮存管理策略等六个解决方法,以及在此基础上的四个建议。同时本文也通过对某个外购厂家进行质量评审的案例,详细介绍了方法的使用过程。本文对企业如何进行外购件质量控制,提供了理论和实践上的指导作用。
[Abstract]:In recent years, with the development of railway locomotive manufacturing industry, the improvement of locomotive product quality has been paid more and more attention. To do a good job in a market, consolidate a market, the important thing is the quality of the product. The quality of the product is related to the survival and development of the company. Under the competitive price advantage, how to produce high-quality locomotive products, occupy the market with quality, and consolidate the market, is the direction for locomotive manufacturers to make unremitting efforts. The earliest locomotives are self-contained production models, except raw materials, most of the components are produced by their own companies. But now the locomotive manufacturing industry, from the point of view of "doing the best", emphasizes on the locomotive design, the production of the key parts, the assembly of the whole vehicle, and the majority of the other parts are purchased out of the market. The product quality of purchased parts plays an important role in the quality of locomotives. The product quality of supplier is also part of R & D and production quality of enterprise. The quality management system of supplier is gradually becoming the quality management system of enterprise. In this paper, the author takes the method of improving the quality of the purchased parts as the research carrier, starting from the situation of the enterprise, the marketing environment and the purchasing situation of the purchased parts, through the analysis of the direct control means of the supplier management, procurement, inspection, storage and quality control of the purchased parts, It is found that there are four problems in the quality control of purchased parts in the company, such as quality control planning, quality data of purchased parts, supplier system control and inventory management, and five basic principles of supplier quality control are put forward. Six solutions, such as quality control project management, supplier development and evaluation strategy, supplier quality cultivation strategy, quality control strategy for key parts and storage management strategy for purchased parts, are carried out for diesel locomotives and diesel locomotives. And four suggestions on this basis. At the same time, this paper also introduces the process of using the method in detail through a case of quality evaluation of an outsourced manufacturer. This paper provides theoretical and practical guidance on how to control the quality of purchased parts.
