单件、小批、多品种生产企业普通存在着高消耗、低效益;投资大、效益差;资产多、增加社会财富少的弊病。新产品上不去,老产品无销路,老经验应付不了新形势。成组技术(GT)正是为了克服这种弊病而产生和发展起来的。国外近十多年来发展很快,如美国于1988年就有人提出“第五代GT”,应用领域日益扩展,实施手段迅速更新。我国GT起步不晚,且曾见效,但由于种种历史性原因,一时停滞不前。1979年实行改革开放,给GT的发展带来了生机。经过这些年来的努力,我国已建立了跨地区、跨部门、跨行业、多学科的学术组织——《全国成组技术研究会》,形成了教育、科研、生产相
Single-unit, small-batch, multi-variety manufacturing companies generally suffer from high consumption and low efficiency; they have large investments and poor returns; they have many assets and increase social wealth. The new products will not go up. The old products will have no outlets. The old experience cannot cope with the new situation. Group technology (GT) was created and developed to overcome this shortcoming. The foreign countries have developed rapidly in the past decade or so. For example, in the United States in 1988, some people proposed the “fifth-generation GT,” and the fields of application have expanded and the means of implementation have been rapidly updated. China’s GT has not started late and it has worked, but due to historical reasons, it has temporarily stagnated. The reform and opening up in 1979 brought vitality to the development of GT. After years of efforts, China has established a cross-regional, cross-sectoral, cross-industry, multi-disciplinary academic organization, the National Group Technology Research Association, which has formed an education, scientific research, and production phase.
