Analyze variant time distribution

You can use the Variant Time Distribution dialog box to highlight problems with product variants. Use this dialog box to scan all the stations and process resources in a zone or line, and:

• Look for product variants that take considerably more time than the takt time in certain stations or process resources. These product variants create a bottleneck on the manufacturing line.

• Look for product variants that take considerably less time than the takt time, which means that station or process resource has capacity.

• Review the probability of the product variants, because problems with common product variants have a greater effect on the manufacturing line.

Analyzing variant time distribution

Procedure

1. In the plant bill of process (BOP), open or navigate to a process area or process line that contains process stations.

2. Click Analyze Variant Time Distribution on the Balancing page.

   The Variant Time Distribution dialog box displays a time line that includes a circle for each worker. The circle location on the time line represents when a worker finishes working with a specific product variant.

3. Hover over a circle to display a tooltip that lists:

     The variant name. In this example, it is LUXURY.
    
   
   
    
     Time required to perform the allocated operations with this variant. 
     In this example, it is 30 sec.
    
   
   
    
     Percent probability of the product variant. In this example, it is 11.93%.
    
   
   
    
     A vertical black line on the chart represents the takt time for the station.
   

4. (Optional) Select a circle to see where and when all work for a specific product variant takes place. This highlights all circles that represent the product variant.

   Information displayed on the right side of the chart describes what each circle represents. This is the same information that is displayed on the tooltip.
