Webel: SysML: SE: A functional analysis «whitebox» Activity may have swimlanes that Allocate to logical subsystems (logical handlers) within the 'problem' zone or to design/implementation level blocks.
MagicDraw/Cameo: The default swimlanes in SysML Activity Diagrams are AllocateActivityPartition swimlanes with the «allocate» keyword applied.

MagicDraw/Cameo: The Allocate relationship is available on many element kinds on most SysML diagram types as a smart manipulator (click symbol once then look at right of symbol).
MagicDraw/Cameo: The Allocate relationship is available in all SysML diagram types under the Common sidebar menu group (but you can only use it to make allocations between elements that both appear in a given diagram).
The allocation table can also be shown using a sparse matrix style as in the following example shown in Figure 15-9. Source OMG Systems Modeling Language (SysML) 1.6
The table shown in Figure D.40 is provided as a specific example of how the «allocate» dependency may be depicted in tabular form, consistent with the automotive example above. Source OMG Systems Modeling Language (SysML) 1.6

The need also arises, when adding detail to a structural model, to allocate a connector (at a more abstract level) to a part (at a more concrete level). Source OMG Systems Modeling Language (SysML) 1.6
For example, if a particular user model includes an abstract logical structure, it may be important to show how these model elements are allocated to a more concrete physical structure. Source OMG Systems Modeling Language (SysML) 1.6
Systems engineers have frequent need to allocate structural model elements (e.g., blocks, parts, or connectors) to other structural elements. Source OMG Systems Modeling Language (SysML) 1.6

In addition, behavior allocation may also include the allocation of Behaviors to BehavioralFeatures of Blocks (e.g., Operations). Source OMG Systems Modeling Language (SysML) 1.6

Behavior allocation relates to the systems engineering concept segregating form from function. This concept requires independent models of "function" (behavior) and "form" (structure), and a separate, deliberate mapping between elements in each of these..

The following paragraphs describe types of allocation that are typical in systems engineering. Source OMG Systems Modeling Language (SysML) 1.6
The Allocate stereotype specializes DirectedRelationshipPropertyPath to enable allocations to identify their sources and targets by a multi-level path of accessible properties from context blocks for the sources and targets. Source OMG Systems Modeling Language (SysML) 1.6
Allocate is directional in that one NamedElement is the "from" end (no arrow), and one NamedElement is the "to" end (the end with the arrow). Source OMG Systems Modeling Language (SysML) 1.6
Allocate is a stereotype of a UML4SysML::Abstraction that is permissible between any two NamedElements. It is depicted as a dependency with the "allocate" keyword attached to it. Source OMG Systems Modeling Language (SysML) 1.6
It is expected that an «allocate» relationship between model elements is a precursor to a more concrete relationship between the elements, their properties, operations, attributes, or sub-classes. Source OMG Systems Modeling Language (SysML) 1.6
