Die Option "Gruppenzuweiung" ermöglicht Ihnen mehrre Vorgänge zu gruppieren und gemeinsam zuzuweisen, so dass Restriktionen wie eine gleicher Beginn eingehalten werden. Die Vorgänge werden dabei mit dem Befehl "Gruppenzuweisung" gruppiert. Für jeden Satz zu gruppierender Vorgänge wird eine Vorgangsgruppe angelegt. Die gruppierten Vorgänge werden von Zuweisungsbefehlen wie "Fertigungsaufträge zuweisen" oder "Aufträge zuweisen/verknüpfen" zugewiesen. Die gleichzeitige Zuweisung von Vorgängen entspricht dabei der bei Zeitbeschränkung MAX und der Ressourcensperre.

Gruppierungseinstellungen

Sie können Gruppierungseinstellungen in der Auftrags- oder in der Vorgangstabelle tätigen.

Auftragstabelle

When making settings to group operations in an order table, the same string is input to “order group”. When an order group is set, an order group object is automatically generated in the order table. This is the same system as the resource groups of an order table, and the item groups of an item table.

When performing group settings in an operation table, “User specified operation group” of the operation table is set. When the “User specified operation group” is set, an operation group object is automatically generated in the operation group table.

The Group operations command references these settings, generates an operation group object, and groups the operations. The operation group object is added to the operation group table. If, for a given operation, both a “User specified operation group” and an “order group” of orders are set, the “User specified operation group” takes precedence. The code of the operation group can be customized with the “Operation group code expression” in the project settings.

As operations are not generated unless rescheduling is done, it is probably easier to perform group settings in an order table. If an “order group” setting is made in an order table, it is possible to select the processes to be grouped by setting the “Group Type” in a process table (see below).

One case in which it is necessary to use the “User specified operation group” of an operation table is when you want to execute the grouping or assign method not for individual orders or individual processes, but for the desired individual operations.

Orte an denen Objekte vom Gruppierungstyp gesetzt werden
Tabelle Eigenschaft Beschreibung
Auftrag Gruppierungstyp If the assignment method is determined order by order,set the group type of the orders.
Prozess Gruppierungstyp If the assignment method is determined process by process,set the group type of the processes.
Vorgang Benutzerdefinierter Gruppierungstyp If the assignment method can be set neither to order nor to process, and you wish to set it for any desired operation, set the user specified group type of the operation.

For example, if the processes to be grouped have been determined, but the assignment method hasn’t, the group setting is done with “order group” of the order table and “group type” of the process table, and the assignment is done with “group type” of the order table. (Siehe Beispiel T und Beispiel T2.)

Gleicher Beginn Weist gruppierte Vorgänge einer Ressource mit gleichem Beginn zu.
Gleicher Beginn auf unterschiedlichen Ressourcen Weist gruppierte Vorgänge mehreren Ressourcen mit gleichem Beginn zu.
  • If there are privileged operations and fixed operations in grouped operations, non-privileged and non-fixed operations are assigned through privileged constrained operation assignment and fixed operation constrained assignment.
  • Regarding the production time of the operation group, work assigned outside the assignment period is ignored.
Durchgängig Weist gruppierte Vorgänge durchgängig einer Ressource zu. If you want to prevent other operations from entering in between operations, you can do this by providing a resource group and assigning an operation group to that resource group with finite capacity. Note that sub resources cannot be made continuous.
  • Operations are assigned in sequence according to property [sequence sort expression] in the group type table.
  • By setting the "Time constraint MAX" property of the group type table, you can set the upper limit of the time interval between the end time and start time of neighboring operations in the starting order.

The time constraint is calculated based on the working time. Therefore, If the end time of operation A corresponds exactly to the end time of the shift of the previous day, and the start time of operation B corresponds exactly with the start time of the shift of the next day across non-working time, the time constraint between operations A and B is considered to be 0 seconds.

  • If there are privileged operations and fixed operations in grouped operations,

non-privileged and non-fixed operations are assigned as privileged constrained operation assignment and fixed operation constrained assignment.

  • Regarding the production time of the operation group, work assigned outside the assignment period is included.
  • The assignment direction is determined mainly based on the privileged operations and fixed operations. Therefore, when the assignment direction of scheduling parameters is backward or forced backward, operations whose starting order is later than that of privileged operations and fixed operations is assigned forward.
    However, at this time, forward scheduling is not desired, so the time constraint with the previous process, the EST of orders, the user specified EST of operations, and so on, are ignored.
Plugin Any desired assignment method can be added with a plugin. For details, refer to EIIFilterCalcGroupedOperationsConstraint in the PlugIn Training EII VC.pdf file of the COM SDK.
Hinweis 
This can be selected if the EIIFilterCalcGroupedOperationsConstraint plugin of the COM interface is enabled.

Zuweisung an Ressourcengruppe

If this setting is set to “Yes”, you can assign operation groups to resource groups. By assigning an operation group to a resource group with finite capacity, the working times of the members of a specific resource group can be used exclusively. Examples are provided for sample T and sample T-2.

When an operation group is assigned to a resource group, the following settings are required.

  • Resources are set in the resource table.
  • Set the “resource type” of the resource group to “Operation group”. When the “resource type” of the resource group is set to “Operation group”, the working time is constructed according to the setting of the calendar table, making it possible to assign operation groups.
    Further, “Resource group load” in the Load graph can now be selected as either “Load of resource group itself” or “Load of all members”.
  • Set the working time of the resource group in the calendar table. To change the resource group itself or the resource quantities of the resources of members of the resource group, set the respective resource quantities to “Resource group quantity” and “Resource quantity”.

Resource groups can also be specified for sub resources (Ver. 13.1 and later). Of the resources to which all the grouped operations are assigned, the resource groups for which Resource class=Operation group in the order of main resource -> sub resource are searched for and assignment is done to the resource group that is found first.

The production time of the working group will be from the earliest production start time to the latest production end time of the grouped operations. You can also add the setup time to the operation group from EIIFilterCalcCombinationSetupDuration of the COM interface.

Planungsparameter

Die Gruppierung erfolgt durch den Befehl "Vorgänge gruppieren". Bevorder Befehl di Vorgänge gruppieren kann, müssen diese von "Vorgangserstellung und Stücklistenauflösung" erstellt werden.

Für den Befehl "Vorgänge gruppieren" gibt es keinen besonderen Eigenschaften. Genauso gibt es auch keine Planungsparametereisntellungen für die Zuweisung gruppierter Vorgänge.

Gruppierte Vorgänge und Vorgangsgruppen werden, so wie bei Zeitbeschränkung MAX und der Ressourcensperre, von allen Zuweisungsbefehlen zugewiesen.

Zeitbeschränkungsart GES

Für die [Zeitbeschränkungsart] in den Integrierten Stammdaten können Sie "GES" für die Definition der zeitliche Beziehung zwischen gruppierten Vorgängen und den nachfolgenden Prozessen setzen. For details see here.

Gantt-Diagramme

Selecting some of the grouped operations on the Gantt chart causes the bars of all the grouped operations to be selected. When an operation is moved, the grouped operations move while satisfying the group assignment constraints.

The members of the order group are displayed in cascade style like a Pegged Order Gantt chart.

Andere Punkte

  • To enable the group assign function, you must select the “Enable group assign” check box in the project settings.
  • Refer to the settings and assignment results of sample T and sample T-2.

Einschränkungen

  • Zur Nutzung der Option "Gruppenzuweisung" ist die entsprechende Lizenz erforderlich.
  • Dynamisches Teilen (auf der Basis von Einstellungen in der Ressourcentabelle oder den Integrierten Stammdaten) ist nicht möglich.
  • Jeder Vorgang kann nur zu einer Vorgangsgruppe gehören.
  • Gruppierte Vorgänge können an Positionen fixiert und gesperrt werden, die nicht de [Zuweisungsart] ihres Gruppierungstypen erfüllen. In solchen Fällen wird die Vorgangsgruppe ohne Beachtung dieser Vorgänge zugewiesen. For example, if the assignment method of the group type is to time fix to locations where the production start times of operations differ although same start time has been set, the operations whose production start time is not the earliest are ignored. In other words, the working time of the operation group does not extend to the assignment position of operations whose production start time is not the earliest.
  • Die hellblauen Linien, die beim Verschieben von Vorgängen angezeigt werden, um den Zuweisugnszeitraum zu veranschaulichen, im dem keine Zeitbeschränkungen verletzt werden, werden für jeden Vorgang einzeln angezeigt.
  • When assignment is done to dummy resources, grouped operations ignore the “Assignment Method” setting of the group type.
  • When assignment is done by forcible assignment with adjustment commands, the grouped operations ignore the “Assign Method” setting of the group type.
