Line balancing

You can use line balancing preferences to manage object properties in the Line Balancing page.

Note

You must add each preference you use to the AWC_StartupPreferences in the Teamcenter rich client.

See the Preferences section in the Active Workspace Administration documentation for a description of preferences and how to set them.

Line Balancing dashboard preferences

The EP_LineBalancingDashboardInformation preference defines which tiles are displayed in the Line Balancing dashboard.

Some of the informational tiles are displayed by default, and cannot be removed. You can add the listed optional values to the EP_LineBalancingDashboardInformation preference to display more tiles in the Line Balancing dashboard.

Value	Description	Default or optional tile
taktTime	Displays the takt time for the assembly line.	Default
cycleTime	Displays the average time it takes to finish one unit of production.	Default
waitTime	Displays the amount of time an item waits for processing or inspection, or to move to the next operation on the assembly line.	Default
unassignedTime	Displays the amount of time a process resource is unassigned on the assembly line.	Default
humanResources	Displays the number of human resources on the assembly line.	Default
cobotResources	Displays the number of cobot resources on the assembly line.	Optional
humanResourcesAndBTI	Displays the number of human resources and the balance time index (BTI) for human resources.	Optional
cobotResourcesAndBTI	Displays the number of cobot resources and the BTI for cobot resources.	Optional
overallEquipmentEffectiveness	Displays overall equipment effectiveness.	Optional
piecesPerShift	Displays the rate at which completed products are produced on the assembly line.	Optional
piecesPerPersonPerHour	Displays the calculation for parts per person, per hour, produced on the assembly line.	Optional
allowance	Displays the extra time that is added to a schedule for delays, unexpected events, or additional tasks. This value is displayed in a percentage.	Optional

Manufacturing time preferences

• The EP_LineBalancingUseBottleneckTime preference defines whether the line balancing calculation is displayed in takt time or in bottleneck mode. The default value is false. Set this preference to true to display the calculation in bottleneck mode.

• The EP_TaktTimeForProductionProgramDefinition preference controls whether to display the takt time chip based on the production line, or based on the product variant in the production program definition (the takt time is defined by the production program definition). The takt time chip is displayed in the Line Balancing dashboard. The default value for this preference is Line. To display the takt time chip based on the product variant, set the default value for this preference to ProductionProgramDefinition.

• The EP_LineBalancingProcessResourceTypesForTotalWaitTime preference calculates the total wait time for all process resource types in the preference value. The default value for this preference is human. You can set the following valid values for this preference:
  
  Human
  
  Cobot

• The EP_LineBalancingCycleTimeIgnoreExternal preference defines whether to ignore or include external operations when computing the cycle time during line balancing. The default value for this preference is false, which means that external operations are included when computing cycle time. Set this value to true to ignore external operations when computing cycle time.

Process resource preferences

• The EP_LineBalancingProcessResourceUtilization preference controls whether process resource utilization displays as a nominal value or a percentage of takt time in the Line Balancing page. The default value for this preference is false, which displays utilization as a nominal value. Set this preference to true to display utilization as a percentage.

• The EP_ProcessResourceCapacityValues preference controls the values in the user interface to set operator capacity. The default values are 50 and 100. You can customize these values for your environment.

• The EP_LineBalancingProcessResourcesTypesForOverview preference defines which process resource types are displayed in the Overview tab. You can set the following values for this preference:
  
  Human
  
  Cobot
  
  Machine
  
  
  Note If the EP_LineBalancingProcessResourcesTypesForOverview preference does not exist in your environment, or the values for the preference are empty, all of the process resource types display in the Overview tab.

• The EP_LineBalancingProcessResourcesTypesForUtilization preference defines which process resource types are in the utilization list. The user can then add a value range for each process resource type. You can set the following values for this preference:
  
  
  
  Human
  
  Cobot
  
  Machine
  
  
  
  Note If the EP_LineBalancingProcessResourcesTypesForUtilization preference does not exist in your environment, or the values for the preference are empty, all process resource types display in the utilization list.

• The EP_LineBalancingResequenceExternal preference enables end users to resequence operations under shared process resources. The default value for this preference is false. Set the value to true to enable this preference.

• The EP_useProcessResource preference allows planners to monitor and manage process resource interactions, which helps reduce resource wait time in production plans.

Note

The process resource interaction feature is active by default. If your environment does not use process resources, set the EP_useProcessResource preference to false to hide this feature.

Process station preferences

The EP_StationDisplayProperty preference determines the station property that displays in the station tile in the Line Balancing page. You can customize this value for your environment.

The default value is bl_rev_object_name, where object_name refers to the revision name. This preference is passed as a string property, and it must be a single value.

To display a different property, change the value for that property to object_string.

Note

If this preference value is missing or incorrect, Teamcenter Easy Plan displays the bl_rev_object_name value in the station tile.

Product variant preferences

• The EP_LineBalancingAllowVariantConfigurationWithProductVariantFiltering preference allows users to configure a plant bill of process (BOP) tree with variant rules or to load a tree that is preconfigured with variant rules. Then you can filter the plant BOP tree according to product variants.

The default value is false. Set this value to true to enable this feature.

Note

This preference applies only in the Line Balancing page.

• The EP_LineBalancingProductVariantsFilterValues preference controls whether to show or hide the Weighted and Maximum product variants in the Line Balancing Product Variant list. The default values for this preference are WEIGHTED:true and MAXIMUM:true. To hide the Weighted and Maximum product variants, set the preference values to WEIGHTED:false and MAXIMUM:false.

Process Planning page role preference

The EP_ProcessPlanningViewModeForRoleME preference defines role configuration for the Process Planning page.

The default value for this preference is false, which leaves the role set for industrial engineers. Set the value of the preference to true to configure the role for manufacturing engineers.

The Process Planning page displays data for each role as follows:

• Industrial Engineers—Data in the Process Planning page displays process resources and the assigned operations under them.

• Manufacturing Engineers—Data in the Process Planning page displays directly under process stations, and process resources do not display on the page.
