The behaviour of norm-autonomous agents is determined by their goals and the norms that are explicitly represented inside their minds. Thus, they require mechanisms for acquiring and accepting norms, determining when norms are relevant to their case, and making decisions about norm compliance. Up until now the existing proposals on norm-autonomous agents assume that agents interact within a deterministic environment that is certainly perceived. In practise, agents interact by means of sensors and actuators under uncertainty with non-deterministic and dynamic environments. Therefore, the existing proposals are unsuitable or, even, useless to be applied when agents have a physical presence in some real-world environment. In response to this problem we have developed the n-BDI architecture. In this paper, we propose a multi-context graded BDI architecture (called n-BDI) that models norm-autonomous agents able to deal with uncertainty in dynamic environments. The n-BDI architecture has been experimentally evaluated and the results are shown in this paper. 相似文献

Cooperative behaviour is one of the challenges most pronounced in the RoboCup Middle Size League. Especially the dynamic nature of the domain, which calls for swift adaptation by each robot and the team as a whole, is a distinctive property of the league. The ability to establish highly responsive teamwork while facing unreliable communication and sensory noise is a key to successful soccer teams. Moreover, modelling such responsive, cooperative behaviour is difficult. In this work, we specify a novel model for cooperative behaviour geared towards highly dynamic domains, focussing on the language syntax and semantics. In our approach, agents estimate each other’s decision and correct these estimations once they receive contradictory information. We provide a comprehensive approach for agent teamwork featuring intuitive modelling capabilities for multi-agent activities, abstractions over activities and agents, and a clear operational semantics. Moreover, we briefly present a graphical modeling tool for cooperative strategies, which is based directly on the theory laid out, together with a practical framework for executing said strategies. We show experimentally the responsiveness and coherence of the resulting team play. 相似文献

In this paper, we argue that allowing self-interested agents to activate social institutions during runtime can improve the
robustness (i.e., stability, reliability, or scalability) of open multiagent systems (MAS). Referring to sociological theory,
we consider institutions to be rules that need to be activated and adopted by the agent population during runtime and propose
a framework for self-regulation of MAS for the domain of electronic marketplaces. The framework consists of three different
institutional types that are defined by the mechanisms and instances that generate, change or safeguard them. We suggest that
allowing autonomous agents both the reasoning about their compliance with a rule and the selection of an adequate institutional
types helps to balance the trade-off between the autonomy of self-interested agents and the maintenance of social order (cf.
Castelfranchi, 2000) in MAS, and to ensure almost the same qualities as in closed environments. A preliminary report of the
evaluation of the prototype by empirical simulations is given.

Faster turnaround time of vessels and high berth productivity are paramount factors in container terminals for assuring competitive advantage in the shipping industry. An autonomous decision-making capability in the terminal is vital in achieving the required productivity. Vessel scheduling/berthing system in a container terminal is regarded as a very complex dynamic application in today’s business world. The Artificial Intelligence (AI) community has been researching in the field of intelligent (or rational) agents for more than a decade and implementations are found in many commercial applications. The Beliefs, Desires and Intention (BDI) agent architecture is probably the most mature model for many industrial applications in today’s context. However, it is not the best agent model for complex applications that must learn and adapt their behaviours in making rational decisions. We propose a new hybrid BDI framework with an intelligent module to overcome the limitations in the generic BDI model. Learning and the adaptability of the environments are assured with the introduction of the Knowledge Acquisition Module (KAM) in the generic BDI architecture in our proposed framework. The dynamic selection of the intention structures has been improved with a trained neural network. The knowledge required to handle vagueness or uncertainty in the environment has been modelled with an Adaptive Neuro Fuzzy Inference System (ANFIS) in berths. Finally, the benefits and the usability of hybrid BDI model for a vessel berthing application is discussed with experiential results. 相似文献

MANET是军用、民用领域都具有很大潜力的一种新型无线网络,大规模MANET的组建必须采用以分簇实现的层次结构。MANET的现有分簇算法一般较少考虑安全性。文中基于MANET的自组织特性和移动节点的Agent特性,采用网络自组织思想及设计规范和理性Agent设计模型,建立了移动节点的BDI对手模型,提出了包含博弈分析的The-Second和Switch-Head算法,并在此基础上建立了一个新的安全分簇算法—BSS。分析表明,此算法具有较好的安全性与较高的性能。 相似文献
