Variant Management BOM in Teamcenter

Variant Management BOM in Teamcenter

Now first to know what is variant, variant is nothing but Variety or assortment is defined as a number or collection of different things of a particular class of the same general kind. Variant is an instance of a class that exhibits usually slight differences from the common type or norm.

  

The above fig shows variant in automobile industry with different option to choose on one single vehicle. Currently the demand of customer is more with different options required in vehicle. To manage such variant Teamcenter provide option to configure BoM with different variant.

Teamcenter support two methods of variant configuration.

1.      Classic variant
2.     Modular variant

Classic variant: if you have limited scope for reuse of generic assemblies. Means if we have not restructure BoM in regularity then we use classic variant.

Modular variant: Enforce modularity to facilitate reuse of lower level assemblies. To do this, you create modules at the top-level item, with variant conditions at all lower levels.

To use modular variants, you require a modular product structure and parts that are engineered for modularity. This may require a change to your design and business practices.

You do not create both classic variants and modular variants in the same product structure, as this may cause in unpredictable results.

Elements of classic variant

1. Option: A parameter of variability. Options have a string type and a name
2.  Variant (BOM): A specific BOM that is configured by applying a variant rule
3.  Variant condition: A condition that an engineering user sets on an occurrence to specify the  option values that configure the occurrence
4.   Variant rule: A collection of option values typically set by a marketing user, to determine the  variant of the BOM to configure
5.   Variant rule check: A condition that specifies any option values or combinations of values that  are not allowed. A variant rule check is attached to an item revision. Also called an error  check.
6.  Constraint: An expression that sets an option value according to the values of other options that  is derived defaults.

    Create small product structure of car assembly in Teamcenter.

    Click on show/ hide data panel and open variant in data panel.

1.    Click on Create variant option ---> Select guide me through step by --->Next ---> Public ---> Next ---> Name of option ---> Next ---> Select option type ---> One word or phrase from a fixed list ---> Next ---> Enter option values ---> Next ---> Select default value as unset ---> Finish.

    Create above steps for Engine type as Diesel and petrol type

    Create above steps for Body system as Ac system and non-ac system

    Create above steps for tyre type as tubeless and with tube

    Next is to select top line of BoM and select Present a child option from this module.

   Select engine type and click on apply, then select body type click on apply, and select tyre type       

   click on apply, check it on variant panel.

   Then after that hide variant panel, and go to set variant condition to each parts as follows.

   Create above step as whole parts in BoM

Click view ---> show ---> unconfigured variants

Click on set variant configuration on tool bar. Click on ok.

     Its means if you select car type as indigo then all indigo then BoM select only indigo parts.
