Introduction to the Activity Tracking Paradigm in Component-Based Simulation

ABSTRACT

Dynamic systems are studied and modeled through the description of state changes (or trajectories). State changes over time constitute the activity of a dynamic system. In a component-based simulation, state changes depend on both computations and exchanges of information. In this paper, the activity tracking paradigm is introduced as a guide for modeling dynamic systems and developing corresponding efficient component-based simulations. Mechanisms and structures to track and describe activity through information are informally and formally introduced.
