hybridisimulointia

Hybridisimulointi, often translated as hybrid simulation, is a computational technique that combines different simulation methods to model complex systems. This approach is employed when a single simulation paradigm is insufficient or inefficient for capturing all essential aspects of a system. For example, a system might involve both continuous physical processes and discrete event-driven logic. A pure continuous simulation might struggle to accurately represent abrupt changes or queueing behaviors, while a pure discrete-event simulation might oversimplify continuous dynamics.

Hybrid simulation bridges this gap by integrating distinct simulation engines or models. One common scenario involves coupling a continuous-time model, such as one based on differential equations, with a discrete-event model representing events, state changes, or logical operations. The interaction between these different modeling domains is managed through interfaces that transfer information and synchronize their execution. This allows for a more comprehensive and accurate representation of systems exhibiting multifaceted behaviors. Applications can be found in diverse fields including manufacturing, logistics, control systems, and biological modeling, where intricate interactions between continuous and discrete phenomena are prevalent. The challenge lies in effectively defining the coupling points and ensuring stable and efficient communication between the different simulation components.
