A multiple station system with variable routing is a group of workstations organized to achieve some special purpose.It is typically intended for production quantities in the medium range (annual production=100to10000 parts or products),although its applications sometimes extend beyond these boundaries.The special purpose may be any of the following:
多站系统具有可变路由是一群工作站组织为达到某种特殊目的。它是一种用于生产数量在介质中的范围(年生产= 100to10000零件或产品),虽然有时超越其应用这些界限。专用可能是下列之行为:
Production of a family of parts having similar processing operations.
Assembly of a family of products having similar assembly operations.
Production of the complete set of components used in the assembly of one unit of final product.By producing all of the parts in one product,rather than batch production of the parts,work-in-process inventory is reduced.
The multi-station system with variable routing is applicable to either processing or assembly operations. It also indicates that the applications usually involve a certain degree of part or product variety,which means differences in operations and sequences of operations that must be performed .The machine groups must possess flexibility to to cope with this variety.一个家庭的零件的生产有相似的加工业务。
一个家庭的产品装配有相似的组装操作。
生产了一套完整的组件的装配中使用一个单位的最终产品。所有的零件,生产一种产品中,而不是在这些零件的批量生产时,对在制品存货减少。
多站系统的具有可变路由是适用的,要么加工、组装业务。它也表明,该应用程序通常包括有一定程度的部分或产品的多样化,这意味着不同的操作,操作和序列,都必须履行.产品组必须具备灵活性来应付这种变化。
The machines in the group may be manually operated,semi-
automatic,or fully automated.In our classification
scheme,manually operated machine groups are type 2.These groups sre often called machine calls,and the use of these cells in a factory is called cellular manufacturing.Cellular manufacturing and its companion topic,group technology,are discussed later.When the machine in the group are fully automated,with automated material handling between workstations,it is also classified as type 2.If an automated machine group is flexible,it is referred to as a flexible manufacturing system or flexible manufacturing cell.
里的机器组可以被手动、半自动或全自动的。在我们的分类系统中,进行手动操作机器组是2型。这些团体都是经常被称为机器呼叫,并且使用这些细胞在一个工厂里被称为细胞制造。细胞制造及其同伴的话题,成组技术,并探讨了以后。当那台机器在那一群人完全自动化,自动化处理材料之间的工作站,它也是划分为2型糖尿病。如果一个自动机器集团是灵活的,它被看作是一个柔性制造系统或柔性制造细胞。
A multi-station manufacturing system with fixed routing is a production line.A prouduction lion consists of a series of workstations laid out so than the part or product moves from onee station to the next,a portion of the total work is performed on it at each station.Production lines are generally associated with mass production(10000-1000000 parts or products per year).Conditions that favor the use of a production line:
The quantity of parts or products to be made is very high(up to millions of units).
The work units are identical or very similar.(Thus they require the same or similar operations to be performed in the same sequence.)
The total work can be divided into separate tasks of approximately equal duration that can be assigned to to individual workstations.
一个多站的制造系统与固定路由是一个生产线。一个生产狮子是由一系列的工作站摆出了,这样,除部分或产品更是从站到明年,部分总工作上被执行它在每一站。通常是伴随生产线大批量生产(10000-1000000零件或产品/年),这样更有利于.Conditions生产线的使用:
