运用6 σ管理法提升物流质量

本文在以往的单纯物流质量研究和单纯6西格玛管理法研究的基础上,尝试着将6西格玛与物流质量进行集成研究.本文从描述物流质量的内容入手,详细分析了6西格玛质量管理法将会对物流质量的各部分内容所起到的作用,最后尝试着重点探讨了如何把6西格玛运用到物流质量管理中,实施6西格玛物流项目的DMAIC.     

六西格玛管理方法在企业中的应用简介

本文介绍了六西格玛管理方法的基本概念及其DMAIC流程的主要工作和主要分析工具,并详细描述了六西格玛管理方法在改善业务流程、降低企业成本当中的应用.     

质量改进——典型的复杂适应系统

产品以满足顾客不断增长的需求为目标,因而产品质量改进是无止境的,是一个典型的复杂适应过程。事实上休哈特的学习过程、计划-做-检查-实施(PDCA)改进环、选择-试验-适应,选择-试验-学习(SEA-SEL)改进模型、以及六西格玛管理所使用的业绩改进模型定义-测量-分析-改进-控制(DMAIC)等几种质量改进模型,都是将质量系统看作复杂适应系统。     

Morgan Systems,Inc.: Application of Six Sigma to the finance function

This teaching case is based on a Six Sigma project undertaken by a subsidiary of a Fortune 100 company to improve its quarterly financial-reporting process. It is presented as a six-phase Problem-Based Learning (PBL) unfolding problem. The first five phases correspond to the stages of the Define–Measure–Analyze–Improve–Control (DMAIC) model, a process-improvement methodology used extensively in Six Sigma. The sixth phase focuses on Six Sigma as a way of doing business.     

DMAIC在提高H产品成品率中的应用

文章按照六西格玛DMAIC流程定义,测量,分析,改进,控制,对本公司H产品成品率低的核心问题进行定义,明确了引起H产品成品率低的两个主要核心问题:浇道残留和排气孔溢料。在测量和分析阶段应用Process Mapping,假设检验,比率检验等方法对可能引起浇道残留和排气孔溢料的原因进行初步的筛选,在改进阶段应用全因子试验设计最终确定了引起浇道残留和排气孔溢料的主要原因,并进行了最优化设计,为了保持改进的成果,在控制阶段,我们对过程建立了有效且适当的控制方法。最终H产品的成品率由原来的96.69%提高到了98.92%,累计为公司节约成本180万/年。     

Apply 6-sigma methodology in measuring the competition quality of satisfaction performance—an example of ISP Industry

At present time the ISP (Internet Service Provider) already make a great impact to the human life as well as the economic society, everything has a close relation with the internet service and due to the fast development of information technology further lower the cost of ISP and improved the service speed as well as its quality. All of this make the customer layer of ISP more popular than before and thus bring up the fierce competition in this industry. Due to the entry barrier of high investment and high technology of ISP industry it has become as a monopoly market and the monopoly market is very respect the competition and cooperation relationship with competitors. Besides, most of the relevant literature in the past is focus on the measurement and analysis of customer to the self-company and few of them mention how to include the satisfaction of competitor’s customer into measurement and analysis. As golden strategy stated in the Sun-Tze Strategic: “Know yourself and know your competitor well, winning every war.” we must consider the strength, weakness, opportunity and threat on customer satisfaction of your company and competitors. Base on the above motivation, this article will apply the DMAIC (Define, Measure, Analyze, Improve, Control) methodology of 6-Sigma, focus on the viewpoint of customer satisfaction of ISP industry. At first we utilize the 5 equal scale measurement define the network quality item of ISP, which provided by the self-company and competitors. And measuring the degree of “satisfaction” and “importance” of these quality items, then use the performance evaluation matrix and strength and weakness matrix to analyze the Strength, Weakness, Opportunity and Threat of self and competitors, focus on the quality items that fall out of the 2 sigma and use the strength–weakness strategic chart to establish the improvement strategy. And at last, utilize the strength–weakness matrix chart as the control tool to verify and sustain the effectiveness of the improved performance. The complete and easy measurement improvement model provided in this article can be used by the enterprise to effectively and quickly evaluating and analyzing the service quality of self and competitors. And under the reasonable cost condition with considering the competing opportunity and threat of market to effectively improving the customer service quality and promoting the overall customer satisfaction and create powerful high value-added quality competition strength.     

浅谈用DMAIC方法解决来料不合格处理时间过长问题之A阶段

六西格码是一种工具,通过五个阶段进行问题的定位与最终解决.以来料不合格处理时间过长问题为例,介绍第三个阶段的处理流程.     

六西格玛及与其它绩效改进工具的比较

本文首先介绍了六西格玛管理的概念,并评述了六西格玛管理的基本方法DMAIC(Define-Measure-Analyze-Improve-Control).文章结合改善库存水平的实例介绍六西格玛项目的DMAIC实施步骤,最后将六西格玛与其它绩效改进工具进行了比较.     

六西格玛改进在项目质量改进过程中的应用

六西格玛管理分六西格玛设计和六西格玛改进两种形式,其中六西格玛改进在项目质量改进过程中得到了更广泛的应用和推广。本文笔者结合自身参与的一项太钢黑带项目(提高热轧带钢成品宽度精度)来介绍六西格玛改进在DMAIC五个阶段如何具体实践,从而使供应商和用户双边产生巨大的经济效益,相信这一实践对若干项目的质量改进都有一定的借鉴意义。
