Hybrid Simulation Modeling Formalism via O

This paper briefly introduces the hybrid simulation modeling formalism via O 2 DES Framework (object-oriented discrete event simulation), and its application in the modeling of mega container ports. From an object-oriented perspective, this paper first lists the entities involved in container ports and the relationships among them; based on it, the "event-based" modeling method is illustrated for its necessity in accurately describing the rules of discrete-event systems, with the case of quay cranes and AGVs interacting with handshakes; then, the hierarchical structure of the model is segmented with a "state-based" modular approach to simplify the process of modeling, as well as the maintenance and reusability of model library; finally, through the "activity-based" perspective, it provides an macro-level overview on the dynamics of the flowing entities in the system. This paper elaborates the connection and cooperation between multiple methods in the hybrid formalism, hoping to provide guidance for future modeling effort.
