装配线 - 分派和装配线工位 (tiasc5520m000)

使用此进程以显示链接至装配线工位的装配线资源分配。此类数据可在装配线控制 (LAC) 中定义,在其中会将此类数据引用为装配线工位级分配。

装配线

A set of consecutive line stations in which FAS (Final Assembly Schedule) items are manufactured. The items are manufactured by passing the items from line station to line station and by carrying out operations at each line station. An assembly line is subdivided into a number of line segments separated by buffers. An assembly line can be either a main line or a supplying line.

装配线工位

A work center that is part of an assembly line. A line station is used in the production of FAS (final assembly schedule) items. A line station can have multiple positions, which enables more than one item to be present in one line station.

分配

The set of resources assigned to an assembly line for a particular period of the day. The resources are divided over the line stations to create a balanced line.

Assignments are defined for an assembly line. For each assignment, you specify the cycle time and its activity ranges, which are the period and time ranges for which the assignment is effective. The process characteristics that you define for an assignment include:

  • Labor FTE
  • Number of Machines
  • Work team
  • Operations

These process characteristics are linked to other assignments that are, in turn, linked to the assembly assignment. When an assignment is in effect, the assignments that are linked to it are also in effect.

assignment types

Two types of assignments exist, both of which exist at the same time. The average assignment is used for more general purposes, whereas the nonaverage assignment has a very specific period and time range.

  • Average assignments

    Use an average cycle time that is based on the cycle times of the nonaverage assignments for the day. The average assignment is used in planning. Planning is based on cycle time, calendar, and availability type.
  • Nonaverage assignments

    Use time-based cycle times that are based on the operations performed on the line. The cycle time can vary according to the time range that is provided for the assignment.

    Nonaverage assignments are used to define order content. For generated (nonfrozen) orders, the order content is based on the first active, nonaverage assignment. For frozen orders, the order content is based on the nonaverage assignment that is in effect at the time that the order is frozen.

    Nonaverage assignments are also used to offset the lead time during sequencing. When the order is sequenced, a lead time is calculated for every order. This lead time is based on the cycle times, and the applicable cycle time is retrieved from the nonaverage assignment.

注意

An average cycle time is not a mathematical average, but is a value that you consider to be a suitable average for the nonaverage cycle times over the course of a full day.

人员固定成本

在装配线工位上为该装配线资源分配工作的员工的数量。

设备固定成本

在装配线工位上为该装配线资源分配所用的机器的数量。

循环次数

在装配线工位上为该分配处理一个装配订单所需的时间。 该时间以循环数表示。 例如,如果生产周期为 2 分钟,则 10 分钟将表示为 5 次循环。
