Mobile Agent based Train Control System for Mitigating Meet Conflict at Turnout

چکیده
Timeliness and correctness in conflict detection and resolution mechanisms form an important component in railway operation especially when the decision process involves human factors. The current approaches used by Indian railways (IR) for conflict management can be enhanced through the use of Mobile Agent (MA) technology. The use of MA technology appropriates due to their asynchronous, autonomous, robust, and fault tolerant properties. In this paper, we discuss certain train operation conflicts and detail about meet conflict followed by implementation of MA based meet conflict management system for IR. Due to the suitability of formal modeling techniques for implementing highly dynamic and concurrent systems, in our rail traffic scenario we modeled the meet conflict detection and resolution mechanism using coloured petri net (CPN). © 2014 The Authors.

A Formal Petri Net Based Model for Antivirus Update Agent System
In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...

Previous research works have demonstrated that traffic control models based on the comparison between an historical archive of information and current traffic conditions tend to produce better results, usually by improving the system’s proactivity behavior. Based on this assumption, we present in this paper MARCS Multi-Agent Railway Control System, a multi-agent system for communications based ...

Double slip turnout is common in heavy haul railway and due to its complex structure, its maintenance is difficult as well as important. Focusing on No.12 double slip turnout (75 kg/m rail), this study analyzed the intensity of the different slotted rubber pad under iron plate and track stiffness of turnout zone based on the finite element method with a purpose of improving the performance of t...
متن کاملCooperative Control of Mobile Robots in Creating a Runway Platform for Quadrotor Landing
Multi-agent systems are systems in which several agents accomplish a mission in a cooperative manner. In this paper, a novel idea for the construction of a movable runway platform based on multi-agent systems is presented. It is assumed that an aerial agent (quadrotor) decides to make an emergency landing due to reasons such as a decrease in energy level or technical failure, while there is no ...
