What type of edge arrangement exists at a merge node?

A merge node in modeling semantics is specifically designed to combine multiple incoming flow paths into a single output path. This structure is essential for controlling the flow of information or actions within a model.

In essence, a merge node receives input from two or more edges, which represent different pathways or decisions that converge at this point. Once this convergence occurs, the merge node facilitates a unified flow, leading to a single outgoing edge. This arrangement simplifies the model and illustrates how different processes or decisions lead to a common outcome, maintaining clarity in the overall flow of control or data.

Understanding this arrangement is crucial, as it helps in modeling decision points and flow dynamics accurately. Thus, recognizing the role of a merge node in consolidating different inputs into one output is fundamental for effective system modeling.
