    This work presents the design of a trust model to derive recommendation trust from heterogeneous agents. The model is a novel application of neural network in evaluating multiple recommendations of various trust standards with and without deceptions. The experimental results show that 97.22% estimation errors are less than 0.05. The results also show that the model has robust performance when ther... View full abstract»

    A knowledge-based test environment for reactive schedulers is proposed. This environment can be used to evaluate and compare the performance of reactive scheduling systems in different scheduling problems including supply chain management problems. The environment simulates autonomous agents that order products, supply raw material, dispatch scheduled operations in a plant and supervise the plan e... View full abstract»

    Most current virtual world systems focus on the interaction between a single agent and the user. This simplification does not reflect the richness of a real social environment. The quantitative increment from the simple two-party interaction to a multi-party interaction does not merely increase the difficulty linearly. In fact, it leads to a much more complex situation involving multimodal communi... View full abstract»

    In most agent-based systems, different middle agents are employed to increase their flexibility. However, there are still three issues remain unsolved. In centralized architecture with single middle agent, the middle agent itself is a bottleneck and suffers from single point failure; middle agents in distributed architecture lack capability of dynamic organization of agents; The reliability is not...

    Traffic at the rush hours is a big problem in every city so that city councils try to encourage citizens to choose mass transportation instead of driving cars. However, this effort is counterbalanced by the fact that travelers' utilities from car usage are more than those from taking buses in most cases. We build a traffic problem model with many agents who have the two options of choosing the car... View full abstract»

    This work presents a learning mechanism that applies nonlinear regression analysis to predict a negotiation agent's behaviour based only the opponent's previous offers. The behaviour of negotiation agents in this study is determined by their tactics in the form of decision functions. Heuristics based on estimates of an agent's tactics are drawn from a series of experiments. The findings of this em... View full abstract»

    The management of interactions among agents in an open multiagent system demands a robust organization mechanism to take care of the entire interaction process. The use of institutional norms to facilitate the guidance of a multiagent society is one well-founded approach to implement organized agent interactions. This work presents a distributed model to organize agent interoperations, using insti... View full abstract»

    Speculative computation is based on abduction, and it can give result of decision in advance based on defaults under incomplete resource information. To achieve goals and reduce risks of decision, master agent in speculative computation makes efforts to obtain more information via negotiation. However, the speculative computation and negotiation have usually deadlines. In This work, framework exte... View full abstract»

    Data mining global models of complex domains is often difficult - a lot of methods are NP-hard as stated in D. M. Chickering et al. (1994) - and the resulting models either lack of details or are far too complex to work with them. In our case we were challenged with the task to model the shopping behavior of customers and the sales behaviour of items within a real supermarket store in order to for... View full abstract»

    Multiply sectioned Bayesian networks (MSBNs) extend Bayesian networks (BNs) to graphical models that provide a coherent framework for probabilistic inference in cooperative multiagent distributed interpretation systems. Observation plays an important role in the inference with graphical models. Since observation of each observable variable has a cost, it would be helpful if we can find the most re...

    We present a two-level coalition formation approach based on a centralized optimization model on the upper level, and a distributed agent-negotiation model on the lower level. This approach allows us to balance agent self-interests against a high joint utility. Experimental results show that the two-level coalition formation mechanism increases not only the overall utility of the coalition, but al... View full abstract»
