Unit 6 Group Technology Group technology is a manufacturing philosophy that involves identifying and grouping components having similar or related attributes in order to take advantage of their similarities in the design and/or manufacturing phases of the production cycle.（成组技术是一个制造业的哲学概念，它涉及到具有相似或相关属性零件的标识和分组，这样我们可利用产品的相似性这种特点，把这种技术应用于产品生产的设计制造过程中） Historically, this novel principle first came into being here in the United States in 1920,when Frederick Taylor supported the idea of grouping parts that required special operations.（历史上，这个新颖的理论是在1920年Frederick Taylor支持将需要特殊加工的零件成组而被第一次提出的）He was followed by the Jones and Lamson Machine Company in the early 1920s,which used a crude form of group technology to build machine tools.（在1920年早期，Jones andLamson公司继承他的思想，他们用粗糙的成组技术形式生产工具）Their manufacturing approach involved such principles as departmentalization by product rather than by process and minimizing the routing paths.（他们使用这一原理的生产方法就是以产品来划分部门，而不是以工艺或缩短路径来划分部门）Today, group technology is implemented through the application of well-structured classification and coding systems and supporting software to take advantage of the similarities of components.（现在，成组技术正在通过运用结构分类、代码系统和支持软件来利用相似零件的优势进一步实施） Reasons for Adopting Group Technology Modern manufacturing industries are racing a lot of challenges caused by growing international competition and fast-changing market demands. These challenges, which are exemplified in the following list, have been and can be successfully met by group technology:（现在制造工业正在接受由日益激烈的国际化竞争和多变的市场要求带来的挑战。这些挑战可以用成组技术成功地解决，如下所列：） *There is an industrial trend toward low-volume production(small lot sizes)of a wider variety of products in order to meet the rising demand for specially ordered products in todays affluent societies. In other words, the share of the batch-type production in industry is growing day after day, and it is anticipated that 75 percent of all manufactured parts will be in small lot sizes.（工业生产发展的趋势是产品的品种更加多样而每种产品生产的数量减少，以此来满足当今繁荣社会不
