Modeling papyrus marthe

I am trying to simulate with papyrus Marte in eclipse, I want to know what is the difference between an association carrying navigation in both directions and one only accessible in one direction.

thank you in advance.

Since it represents a link, the association has two ends. The end of the union is modeled using a UML property that may belong to the classifier participating in the corresponding end of the association, in which case the association is considered navigable since the source classifier can directly refer to the target instance (the instance at the other end of the association) using this property. Otherwise, the property representing the end of the association may be owned by the association instance itself.
