Chapter 13. Modeling Cross-Cutting Relationships with Allocations

This chapter describes how allocation relationships are used to map from one model element to other model elements to support behavioral, structural, and other forms of allocation.

Overview

Beginning early in systems development, the modeler may need to associate various elements in the system model in abstract, preliminary, and sometimes tentative ways. It may be inappropriate to impose detailed constraints on the solution too early in the development of a system’s architecture. Allocation is a mechanism to relate model elements that is typically a prelude to more rigorous relationships that are established through follow-on model refinement. Additional user-defined constraints can ...
