【摘要】：随着中国改革开放的深入，中国在世界经济中的作用越来越大，我国的制造业也已经越来越成为世界的制造中心，，但是与此不相匹配的是目前我国的产品质量基础还很薄弱、质量保障能力还不高，产品的总体质量还不够强，并且产品质量频频波动。面对市场激烈的竞争和产品多样化的需求，企业的生产方式已经由大批量生产转变为多品种小批量生产。顾客对产品的质量需求也在不断的提高，受国际经济不景气和其他因素综合的影响，多品种小批量生产企业必须重视质量改善，通过不断进行质量改善提高企业效益和竞争力。本文首先研究了多品种小批量生产企业生产的特点，并对目前很多生产制造企业，特别是汽车生产企业主要用于处理顾客投诉的8D理论其特点、优缺点及应用范围进行了深入的探讨。在此基础上分析了8D在此类型企业中的进行质量改善的意义、理论基础和改善的条件，并提出了相关的改善策略。通过对8D在JH企业生产质量异常改善的实证分析，证明了JH企业运用8D进行的质量改善是成功的，并且取得了相应的效果。鉴于8D本身只关注于问题解决可能忽视整体的质量改善绩效这一缺点，在对质量改善和质量改善绩效理论研究的基础上建立了质量改善绩效评价指标体系，运用数据包络分析法对JH企业质量改善绩效进行了分析,得出结论是JH企业质量改善绩效为有效，从实践上证明了8D在多品种小批量生产企业进行质量改善的可行性和有效性。
[Abstract]:With the deepening of China's reform and opening up, China is playing a more and more important role in the world economy, and our manufacturing industry has become more and more the manufacturing center of the world. However, what does not match this is that the quality basis of our products is still very weak at present. The quality assurance ability is not high, the overall product quality is not strong enough, and the product quality fluctuates frequently. In the face of fierce market competition and diversified product demand, the mode of production of enterprises has changed from mass production to multi-variety and small batch production. The customer's demand for the quality of the products is also increasing. Under the influence of the international economic depression and other factors, the multi-variety and small-batch production enterprises must pay attention to the quality improvement and improve the efficiency and competitiveness of the enterprises through continuous quality improvement. This paper first studies the characteristics of multi-variety and small-batch production enterprises, and analyzes the characteristics of 8D theory, which is mainly used to deal with customer complaints in many manufacturing enterprises, especially automobile manufacturing enterprises. The advantages and disadvantages and application scope are discussed in depth. On this basis, the significance, theoretical basis and conditions of improving the quality of 8D in this type of enterprise are analyzed, and the relevant improvement strategies are put forward. By analyzing the abnormal improvement of 8D production quality in JH enterprises, it is proved that the 8D quality improvement in JH enterprises is successful and the corresponding effect has been obtained. In view of the fact that 8D only pays attention to the problem solving and neglects the overall quality improvement performance, a quality improvement performance evaluation index system is established on the basis of the theoretical research on quality improvement and quality improvement performance. This paper analyzes the quality improvement performance of JH enterprises by using data envelopment analysis, and draws the conclusion that the quality improvement performance of JH enterprises is effective. The feasibility and effectiveness of 8D quality improvement in multi-variety and small batch production enterprises are proved in practice.
