Systems Based On Agent And Cellular Automata

Abstract
A train control system is a system that is geographically and functionally
distributed. Its subsystems have a high degree of autonomy. Because of these
characteristics, this paper describes a two-layer framework for modeling train
control systems. The upper-layer is defined by agents. The lower-layer is the
cellular automata (CA) traffic model to simulate the train following dynamic.
The CA model delivers the knowledge needed by the agents to make decisions.
The interaction between agents can describe the decision-making processes of
train control systems to achieve its functions. Its functions are classified into
three levels: Service Control Functionality, Signaling Functionalities and Train
Operation Functionality. A case study is used to illustrate the applicability of the
proposed framework. The study results show that the proposed framework can
be successfully used to analyze the influence on traffic flow, which is caused by
the train control system.
Keywords: modeling, train control system, agent, Cellular Automata (CA).
1 Introduction
A train control system model is an important tool to research train control
systems. The previous models are based on the equipments that are used in the
practical train control system. For different train control systems, they may have
different equipments. In other word, the equipments that constitute the train
control system can be tailored towards requirements. This leads to different
systems having different system configurations. It is possible to accept the nonuniformity
of the configurations in practical projects; however, it is not
conducive to understanding the train control system.
