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 today's 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断增长的专门订货。换句话说，工厂中分批式生产的比例越来越高，预计将来全部的75%是小批量的。） *As a result of the first factor, the conventional shop organization is becoming very inefficient and obsolete because of the wasteful routing paths of the products between the various machine tool departments.（作为第一个因素的结果，传统的车间机构变得越来越低效和过时，因为产品在不同的工具部传送的时候浪费时间）
*There is a need to integrate the design and manufacturing phases in order to cut short the lead time, thus winning a competitive situation in the international market.（有必要把设计和制造的阶段集成在一起可以减少订货至交货的时间，这
