Activity scanning approach

Definition

The activity scanning approach is a method used in discrete-event simulation to analyze the sequence and timing of events within a system by identifying and tracking specific activities that contribute to overall performance. This approach focuses on capturing the dynamic interactions between various components, allowing for a clearer understanding of how changes in one part of the system can affect others. By mapping out activities and their interdependencies, this technique helps in identifying bottlenecks, resource utilization, and overall efficiency.
