14.12 Summary

The allocation relationship provides significant flexibility for relating model elements to one another beginning early in the development process. Key concepts for modeling allocations include the following.

ent An allocation relationship is a form of mapping between model elements that provides the capability to assign responsibility associated with one model element to another.

ent Use of allocation enables certain implementation decisions to be deferred by specifying the model at higher levels of abstraction and then using allocations as a basis for further model refinement.

ent There are many different types of allocation, including allocation of behavior, structure, and properties. Allocation supports traditional systems engineering concepts, such as allocating behavior to structure by allocating activities to blocks. Also supported is allocation of logical elements to physical elements, including logical connectors to physical interfaces, software to hardware, object flows to item flows, and many others.
