对任何生产过程来说,要取得最大的经济效果,无非在两方面下功夫:一是在组织管理上,提高工效,减少窝工浪费;二是选择最佳工艺参数,以便用最短的时间,最大的效率,最低的成本,生产出质量优良的产品。第一个问题就牵涉到统筹法,第二个问题牵涉到优选法。在国外,研究组织管理方法的名称很多,主要叫“计划评审技术”(PERT)和“关键路线法”(CPM)。国内外应用统筹法是在五十年代末期。这个方法简略地说,就是先把每个管理项目的工序组成,工序前后的衔接关系,每道工序所需的工时,画成一个网络图,就叫做统筹图。所谓统筹法,就是运用统筹图表达生产工艺和 For any production process, to achieve maximum economic results, there are two aspects: First, in terms of organization and management, to improve ergonomics and reduce wastage; the second is to choose the best process parameters in order to use the shortest time possible. The greatest efficiency, the lowest cost, produces excellent quality products. The first issue involves a co-ordinated approach, and the second issue involves a preferred law. In foreign countries, there are many names of research organization management methods, mainly called “Planning Review Technology” (PERT) and “Critical Route Method” (CPM). Domestic and international application of the law of integration was in the late 1950s. This method is simply to say, that is, the composition of the processes of each management project, the connection relationship before and after the process, and the time required for each process are drawn into a network diagram, which is called the overall plan. The so-called co-ordinating law is the use of a unified plan to express the production process and
