The traffic congestion problem in urban areas is worsening since traditional traffic signal control systems cannot provide] efficient traffic regulation. Therefore, dynamic traffic signal control in Intelligent Transportation System (ITS) recently has received increasing attention. This study devised a multi-agent architecture, the Adaptive and Cooperative Traffic light Agent Model (ACTAM), for...

Team VaCAS developed a cooperative unmanned ground vehicle (UGV) system for MAGIC 2010 competition. The system includes a cooperative estimation and control strategy, its software, UGVs and the so-called platformand hardware-in-the-loop simulator (PHILS) which allows the performance evaluation of multi-UGV system in a virtual environment. Team VaCAS also constructed outdoor and indoor test area...

In this paper, we consider the problem of collision-free motion planning for multiple nonholonomic planar vehicles. Each vehicle is capable of moving at constant speed along paths with bounded curvature, and is aware of the position and heading of other vehicles within a certain sensing radius. No other information exchange is required between vehicles. We propose a spatially decentralized, coo...

This paper studies the decentralized kinematic control of multiple redundant manipulators for the cooperative task execution problem. The problem is formulated as a constrained quadratic programming problem and then a recurrent neural network with independent modules is proposed to solve the problem in a distributed manner. Each module in the neural network controls a single manipulator in the ...

Price of Anarchy is an oft-used worst-case measure of the inefficiency of non-cooperative decentralized architectures. For a non-cooperative load-balancing game with two classes of servers and for a finite or infinite number of dispatchers, we show that the Price of Anarchy is an overly pessimistic measure that does not reflect the performance obtained in most instances of the problem. We expli...

The paper analyses non-cooperative behaviour in a two-echelon decentralized supply chain, composed of one supplier and n retailers. For sufficient supply from the supplier, we build the approximate decision model of their base stock level, in which the suppliers reactions are not considered, and its non-cooperative behaviour is obtained. For insufficient supply from the supplier, much more comp...
