4.4. Allocation
An allocation is a general mechanism from the field of systems engineering to interconnect elements from different model areas. For example, binding an item flow in the internal block diagram, which occurs in a different form, as an object flow, in an activity diagram (Figure 4.21). Such a binding is normally present in a complete model through a wealth of details and deeply hidden paths, and not visible at a glance. A systems engineer cannot penetrate these detail depths. Nevertheless, they want to model the connections, even in an early project phase.

There are different types of allocations. SysML proposes three general types and let’s the developer ...
