Option Combination

While you can represent many option relationships using inclusive and exclusive options, there are times when a group of options have a complex relationship with each other. You can define these complex relationships by specifying the allowable combinations of a group of options.

This, in turn, helps to limit the potentially large number of harness levels that Composite Wiring Synthesis can generate.

An option combination is a collection of options that you have arranged into specific, valid selections.

For example:

If no inclusive or exclusive relationships exist between the 6 options A, B, C, D, E, F, and they are all optional in a particular vehicle model, then there are 64 possible combinations. In order to lower the complexity (or for other design reasons), you can select the 6 options in an option combination and arrange them to permit only the following combinations:

• (A, B, C, D, E, F)

• (B, F)

• (A)

• (F)

Each of the 4 combinations of the original 6 options is known as a valid selection (that is, there are only 4 valid selections in the option combination).

The following considerations apply to option combinations and valid selections:

• An option can exist in either no option combination or just one option combination (that is, not multiple option combinations).

• An option combination does not have to include a valid selection where all options are selected.

• Within an option combination, the only limitation on its valid selections is that they must conform to any normal inclusive/exclusive relationships between the options.

• If it is permitted for none of the options in an option combination to apply to a vehicle, then you must create an explicit, empty valid selection for that option combination.

For an example of an option combination and its valid selections in a project, see Examples of Composite Data.
