Options and Option

Relationships

Options and variant options can be created at project level from the design applications. An option is a code representing a feature or capability in a vehicle. Options are used in expressions to convey the conditional inclusion of an object in a particular vehicle configuration.

Once created for a project, an option may be applied to any of the designs created within that project. The options applied to designs are known as “Applicable Options”.

There are three ways in which you can define relationships between options at project level:

• Define inclusive and exclusive relationships for individual options.

• Group them within option folders that allow you to specify whether the options in the folder are mutually exclusive (that is, none of the options within this folder can be selected together in a vehicle) or mandatory (that is, at least one of the options within this folder must be selected in a vehicle). At system or project level.

• Create option combinations that allow you to specify valid selections of options. Option combinations and valid selections allow the representation of complex relationships between a group of otherwise unrelated options by specifying their allowed combinations. Option combinations reduce the allowable combinations of a set of options, which in turn helps to limit the potentially large number of harness levels that can be generated by the Composite Wiring Synthesis (CWS) procedure in Capital Systems Integrator. An option combination is a collection of options that have been 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, there are 64 possible combinations. In order to lower the complexity (or for other design reasons), the 6 option can be selected in an option combination and arranged 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 an explicit, empty valid selection must be created for that option combination.
