Object-Oriented Simulation (OOS) is a methodology that takes advantage of the rules of object-oriented programming (OOP) to product techniques. In OOS, the method is split into objects that symbolize genuine-environment entities.

OOS is very practical when simulating complex methods with numerous interdependent components, enabling designers to model method-level behavior rather than just individual factors.

three.4. Agent-Primarily based Modeling (ABM)
Agent-Primarily based Modeling (ABM) is really a type of simulation that models units as a set of agents. An agent is an individual entity throughout the process which has its personal list of attributes and behaviors. These agents connect with each other as well as their natural environment, and their steps can cause sophisticated, emergent behaviors at the process degree.
