The SysML specification defines the allocation relationship in order to be have "an effective means for navigating the model by establishing cross relationships, and ensuring the various parts of the model are properly integrated". The allocation relationship is a dashed line with an open arrow head but it can also be depicted in tables (or Modelio matrix).
SysML Architect allows the possibility of creating a global allocation matrix summarizing in a matrix from all existing allocations. For creating a SysML allocation matrix, select your root folder, then SysML a as shown in Figure 1.

The Figure 2 represents the result of the allocation matrix creation.
