A default grouping chain maps the standardized, logistical concepts of sequences and shopping carts (also car sets).
As for the default process and default disposal chains, the number of stages, the processes performed at each stage, transport processes, as well as the transport type and empties transports can also be defined here.
The same basic functions are available for the default grouping chains as for the default process chains. You can find the complete article on the default process chains here.
Creating a default grouping chain
The display when creating a default grouping chain looks as follows:
|1||Adding a new stage|
|2||Deleting a stage|
|3||Selection of the transport container - either grouping box or grouping unit|
|4||Consideration of default disposal chains for the transport of empties|
|5||Choice of transport mode - For direct transport this includes the definition of the direct transport mean and, if applicable, workers|
|6||Display of the process times|
To the stages (1):
A layout level can be defined for each level. The selection of this is done by the button in the respective level (see 1). All layout levels defined in the layout structure can be selected.
If no layout level is defined, the level Hall can also be selected. All areas are assigned to this level by default. The areas of the hall of subordinate levels can also be selected if Hall is selected as layout structure.
To the transport containers (3):
Two different transport containers - grouping load carrier and grouping load unit - are available to the user.
The input type of the transport container on the following stage is always defined by the output type of the transport container of the upstream stage.
To the shipments (5):
There are two different types of transport selection. Route stands for a shipment with the route train, always consisting of a tugger and trailer. As soon as Route is selected, the previously red area appears green.
However, if the transport is carried out with a forklift or AGV, the term Direct must be defined in the ComboBox. If this type of transport is selected, the means of transport and, for manned means of transport, the worker must also be selected.
For transports of empties (4):
In addition, there is also the option of taking into account transports of empties. More details can be found here.
On the processes (6):
Stage processes and loading / unloading processes must be defined for each stage. This is done using the button + worker process / + loading/unloading process below each stage and transport (see 1).
The process is added and is highlighted in red until it is completely defined. For stage processes, the respective worker (see 2), the process (see 3), and the reference value (bundler container, bundler placed or part, see 4) must be entered. For loading and unloading processes, only the process must be defined (see 5), a worker cannot be defined.
Several processes can be assigned to one worker. If a process has already been created, you can add another one by choosing + process (see 6).
The data for selecting the workers and the percentages for calculating the distribution times come from resource management, the process names and times from the process building block administration.
Calculation of the process durations
|Process time||Sum of the pure process time of all processes|
|Distribution time||total distribution time [%] * pure process time of all processes|
|Total time||Sum of distribution and process time|
Use of the created default grouping chains in the existing default process chains:
Once defauilt grouping chains have been created, they can be assigned to the individual default process chains. For this purpose, the container type "Grouping load carrier" or "Grouping load unit" must be selected as container type in stage 1 of the respective default process chain(see 1). As soon as the user selects the grouping here, there is a new combo box to the right of level 1 in which the respective default grouping chain can be selected (see 2):
