DynCNET: A Protocol for Dynamic Task Assignment in Multiagent Systems

Danny Weyns, Nelis Boucke, Tom Holvoet, Bart Demarsin
2007 First International Conference on Self-Adaptive and Self-Organizing Systems (SASO 2007)  
In this paper, we introduce DynCNET, a protocol for dynamic task assignment that extends standard contract net (CNET).  ...  Task assignment in multiagent systems is a complex coordination problem, in particular in systems that are subject to dynamic and changing operating conditions.  ...  Such a problem setting requires a flexible task assignment approach that is able to cope with dynamics in the system. In this paper, we introduce a protocol called DynC-NET.  ...

DynCNET: A Protocol for Flexible Task Assignment Applied in an AGV Transportation System

Danny Weyns, Nelis Boucké, Tom Holvoet, Kurt Schelfthout
2006 European Workshop on Multi-Agent Systems  
We compare the DynCNET protocol with CNET and FiTA in an AGV transportation system.  ...  DynCNET is an extention of CNET, with "Dyn" referring to support for dynamic task assignment. DynCNET provides flexibility and openness for assigning tasks with delayed commencement.  ...  Introduction Task assignment in multiagent systems (MAS) is complex, especially in systems characterized by highly dynamic and changing operating conditions.  ...

A field-based versus a protocol-based approach for adaptive task assignment

Danny Weyns, Nelis Boucké, Tom Holvoet
2008 Autonomous Agents and Multi-Agent Systems  
Task assignment in multi-agent systems is a complex coordination problem, in particular in systems that are subject to dynamic and changing operating conditions.  ...  In DynCNET, agents use explicit negotiation to assign tasks. We compare both approaches in a simulation of an industrial automated transportation system.  ...  Acknowledgement Danny Weyns is supported by the Funding for Scientific Research in Flanders (FWO).  ...

Self-Adaptation Using Multiagent Systems

D. Weyns, M. Georgeff
2010 IEEE Software  
The DynCNET protocol, in combination with the goal-directed, contextsensitive process selection, enables the agents to reconsider the environmental situation and adapt the task assignments dynamically  ...  In multiagent system engineering, developers often consider "agentification" to be a general Figure 2. DynCNET protocol. The start() operation initiates the protocol.  ...

Architectural design of a situated multiagent system for controlling automatic guided vehicles

Danny Weyns, Tom Holvoet
2008 International Journal of Agent-Oriented Software Engineering  
To cope with new and future system requirements such as flexibility and openness, we have applied a situated multiagent system to developed a decentralized control architecture for AGV transportation systems  ...  In this paper, we give an overview of the software architecture of the system and we zoom in on two specific concerns: transport assignment and collision avoidance.  ...  ACKNOWLEDGMENTS Danny Weyns is supported by the Research Funding of the Katholieke Universiteit Leuven and the Funding for Scientific Research in Flanders (FWO).  ...

A pattern language for multi-agent systems

Danny Weyns
2009 2009 Joint Working IEEE/IFIP Conference on Software Architecture & European Conference on Software Architecture  
In this paper, we present a pattern language for multi-agent systems.  ...  Developing architectural support for self-adaptive systems, i.e. systems that are able to autonomously adapt to changes in their operating conditions, is a key challenge for software engineers.  ...  DynCNET enables the agents to reconsider the situation in the environment and adapt the assignment of tasks when circumstances change, improving flexibility and openness.  ...
