Best-kept secret agent revealed

Best-kept secret agent revealed - No longer just the province of specialist sectors, agent-based computing is changing the way systems interact and how they are managed. By Boris Sedacca.

"Agent-based computing has already transformed processes such as automated financial markets trading, logistics, and industrial robotics. Now it is moving into the mainstream commercial sector as more complex systems with many different components are used by a wider range of businesses. Organisations that have successfully implemented agent technologies include DaimlerChrysler, IBM and the Ministry of Defence.

So what are agent technologies? In essence, they are autonomous software systems that can decide for themselves what they need to do. Agents are capable of operating in dynamic and open environments and often interact with other agents - including both people and software. 'Agents are a way to manage interactions between different kinds of computational entities, and to get the right kind of behaviour out of large-scale distributed systems,' says Michael Luck of the School of Electronics and Computer Science at the University of Southampton and executive director of the EU-funded AgentLink action co-ordination programme. 'The idea of grid computing is based on large-scale distributed computation in support of what are called virtual organisations. All they need to do is to be able to interact.' ...

The notion of agent-based computing has been adopted enthusiastically in the financial trading community, where autonomous market trading agents are said to outperform human commodity traders by 7%. ... In the manufacturing sector, Daimler­Chrysler implemented an agent-based system on one factory floor to allow individual work pieces to be directed dynamically around the production area. The intention was to implement flexible manufacturing to meet rapidly changing operations targets. The result was claimed to be a 20% increase in productivity. ... In traditional object-oriented systems, the software is controlled by a central thread. 'However, agents are more active than regular objects, and the key difference is that agents are event-driven,' says [Mark] Hinton. "
