Abstract
As railway signalling systems hardware improved from mechanical switches and
electrical relays to electronic tubes and semiconductors, the software improved
from direct control and event-driven approach to object and agent-oriented
programming.
This paper aims at the use of agent-oriented programming for railway
applications. In order to do that some agent basic concepts such as organizations
(reactive and cognitive), models (beliefs/desires/intentions and social) and
interactions (independent and collaborative) between agents are presented.
The AOSE (Agent Oriented System Engineering), as OOSE (Object Oriented
System Engineering) some time ago, is a paradigm on multi-agent programming.
The main difference between an agent and an object is that the agent must have
autonomy while an object must not. An object property is only activated when a
control program asks for that property. An agent, instead, must start and manage
its own properties in order to perform its objectives.
Therefore, a model proposal for train control systems is presented based on
multi-agent programming paradigm. In this proposal, trains and stations are
modelled as interacting agents, working together in order to achieve a common
goal: an optimized train traffic control. Some profits and drawbacks of this
approach are also addressed, detaching the importance of multi-agent approach
characteristics for railway and train control applications. The AOSE supplies
many tools for multi-agent systems design and programming.
