The rapid growth in technology has made the computer a vital tool for a wide variety of applications. Software that aids the common user in performing routine computing chores have now become commonplace. With the Internet growing rapidly, numerous new sites are coming into existence each day. This necessarily means that a user has to spend more time and energy to search for a particular piece of...
We study on the Prisoner’s Dilemma game on network to clarify the influence of the network structures on agent strategies, and vice versa. A model is proposed to treat an interaction between the agent strategies and the network formation process. In case of a fixed network, it is observed that the distribution as well as the propagation speed of an agent strategy depends on the network structure....
The field of multi-agent systems shifts attention from one particular agent to a society of agents; hence the interactions between agents in the society become critical towards the achievement of their goals. We assume that the interactions are managed via an agent protocol which enables agents to coordinate their actions in order to handle the dependencies that exist between their activities. An...
Rational agents must be aware of their success and failure to truly assess their own progress towards their intended goals. In this study we describe a detailed investigation of how current BDI agents monitor their successes and failures during their reasoning cycle. Our analysis indicates that the existing architectures are inadequate to specifically detect failures in their own behaviors. This makes...
This study, taking reference of “Generic Workflow Production Structure, GWPS” proposed by WfMC and combining with design concepts of the Multi-Agent System, sets forth “Agent-Based Workflow Management System Architecture” and implements it onto the JADE (Java Agent DEvelopment Framework) platform. Taking Conference Info System as an example, this study analyzes, designs and implements Agent-Based...
A Logic of Multiple-valued Argumentation (LMA) was formalized by Takahashi and Sawamura on an expressive knowledge representation language, Extended Annotated Logic Programming (EALP). LMA allows agents to construct arguments under uncertain knowledge and to argue with other agents on uncertain issues in the open networked heterogeneous environment. In this paper, we demonstrate its expressiveness...
Multi-agent system(MAS) has more advantages because the agents can collaborate to complete complex tasks. However, the multi-agent interactions are more complex and even uncontrolled and it is difficult to resolve the multi-agent collaborations. This paper focuses on the interaction protocol in MAS. Firstly the interaction ontology library including role ontology, action ontology and message ontology...
The component-based design of software systems has long been recognised in the realm of software engineering as a method for building highly adaptable and maintainable software systems. This paper explores the principles behind software agent-orientated frameworks and the component-based design of software agents. The ideas and principles discussed are then used in the introduction of our AgentAssembly...
The mobile agent technology is considered to be very useful for ubiquitous environments. But in order to apply the mobile agent concept to ubiquitous devices, the mobile agent platform should be lightweight because the devices in ubiquitous environments have very limited computing resources. Normally, the ubiquitous devices have J2ME CLDC environments. But this environment has very limited functionality...
This paper discusses the need to incorporate the notion of active perception in intelligent agent systems. There are two justifications for this proposition. First, we believe perception should receive more attention and some special treatment. Perception is the most direct and effective way to update an agent’s beliefs about the status of its environment. In theory, an overwhelming portion of an...
Distributing profit in a coalition of multiple cooperating agents [3] is an important issue in both multi-agent and economics society. Proposed in 1953, Shapley value scheme with its elegant axiomatic derivation is essential to solution concepts for profit sharing. However, Shapley value scheme did not cover fairness issues. A new scheme of profit sharing with fairness awareness is proposed in this...
Many multi-agent interactions, like auctions and negotiations, can be modeled as games. Game theory is a tool to analyze these multi-agent applications as games and to analyze how agents should interact in these applications, which helps design intelligent agents. In many of the existing solutions to these multi-agent applications, the concept of risk is used, but it is not formally defined in game...
We describe a crowd model in emergency and panic situations. First, we describe the crowd structure of our model that comprises a combination of group-based and individual-based agents. This is followed by a description on the agent’s characteristics and its behaviours for emergency and panic situations. Detailed descriptions on agent’s behaviours including graphical illustrations and pseudo-scripts...
Graphical utility models represent powerful formalisms for modeling complex agent decisions involving multiple issues [2]. In the context of negotiation, it has been shown [10] that using utility graphs enables reaching Pareto-efficient agreements with a limited number of negotiation steps, even for high-dimensional negotiations involving complex complementarity/ substitutability dependencies between...
An organizational information management system for multi-agent systems (MASs) on the Internet, called ARTISTE, is proposed. For an MAS to solve problems effectively, it is important to organize agents appropriately. Organizing agents adaptively on the Internet, however, is not easy, because the status of the Internet changes dynamically in a short time and no one can have a complete view of the whole...
In sensor networks, each sensor has very limited capability in battery life and processing power. This problem can be solved by employing a middleware system which can reduce the load of each sensor to expend the each sensor’s battery life and provide the proper control of the sensed data. In this paper, we propose a middleware model using multi-agent for small-area sensor networks. This model is...
In ubiquitous environment, each agent tires to aware the context. Usually, the context which agent tries to recognize, consists of different information. Even if several agents are in the same environment, each agent’s contexts are different. As every agent has different intention in the process of interaction with the environment, the view of each agent to the environment is different from others’...
Request for Proposal (RFP) problem is a type of task allocation problem where task managers need to recruit service provider agents to handle complex tasks composed of multiple sub-tasks, with the objective being to assign each sub-task to a capable agent while keeping the cost as low as possible. Most existing approaches either involve centralized algorithms or require each agent’s cost for doing...
