This paper presents the CoMoMAS methodology and environment for the development of multi-agent systems. We use a conceptual model set to describe a multi-agent system under different views. These models are derived from the knowledge-engineering methodology CommonKADS. In contrast to CommonKADS, our approach takes several agent-specific aspects into consideration, in particular, the use of additional...
This paper focuses on the design of multiagent systems using object oriented design patterns. In earlier papers the distinctions and relationships between agents and objects were discussed; these findings are employed here as a foundation for a multiagent system architecture. Patterns are flexible, reusable, and effective object oriented designs. The role of design patterns for multiagent systems...
In this paper, the author describes a graphical conceptual modelling language called MODEL-ECS that is used to model the components of a mobile agent. The use of this language to model the PROJECTION COMPONENT of the Perception Mechanism of a mobile agent is demonstrated. This modelling language uses conceptual structures (i.e., Conceptual Graphs, Actor Graphs, and Problem Maps) as its primitive modelling...
Fundamental to the operation of multi-agent systems is the concept of cooperation between individual agents by which the overall system exhibits significantly greater functionality than the individual components. Not only is it important to understand the structure of such relationships in multi-agent systems, it is also important to understand the ways in which cooperative relationships come about...
Adaptation in open, multi-agent information gathering systems is important for several reasons. These reasons include the inability to accurately predict future problem-solving workloads, future changes in existing information requests, future failures and additions of agents and data supply resources, and other future task environment characteristic changes that require system reorganization. We...
We introduce a collaboration framework called ACACIA for multi-agent systems (MAS). ACACIA is a high level framework that focuses on heterogeneous agents. Our main goal is to create a collaboration framework that precludes the re-engineering of existing software agents. We also apply a case-based coordination scheme in which a database of collaboration protocols can be consulted during the collaboration...
We propose a multi-agent cooperative reasoning system for amalgamated knowledge bases. A multi-agent cooperation environment, where inconsistency is allowed, can be presented by an amalgamated knowledge base. Our reasoning method is an extension of the magic sets technique [2] for amalgamated knowledge bases, augmented with the capabilities of handling amalgamated atoms. Through rewriting a given...
When a set of autonomous agents are going to decide on a global plan, it may be difficult to determine whether the set of common goals is nonempty. Furthermore, even if the combined plan is consistent, it may be hard to determine the set of common goals. We present a formal framework for the analysis of conflicts in sets of autonomous agents restricted in the sense that they can be described by first-order...
Agents in a multi-agent environment must often cooperate to achieve their objectives. In this paper an agent, B, cooperates with another agent, A, if B adopts a goal that furthers A's objectives in the environment. If agents are independent and motivated by their own interests, cooperation cannot be relied upon and it may be necessary for A to persuade B to adopt a cooperative goal. This paper is...
In this paper, several methodologies for designing synthesis strategies in distributed expert systems are investigated. They are analytic methods, inductive methods, and analogical methods. Firstly, synthesis problems are formally described. Secondly, the measurements for synthesis strategies are formally defined. After that, all methodologies are analyzed thoroughly and corresponding examples are...
We present an implementation of an automated reasoning system for multi-agent knowledge and time, which can be used to describe multi-agent environments. Our reasoning procedure is based on a so-called semantic method. That is, suppose that a multi-agent environment is given by a multi-agent knowledge and time modal logic formula set U. To see whether a multi-agent knowledge and time modal logic formula...
Pricing and prioritizing the Internet access can be one of the potential measures to improve the efficiency of the Internet utilization and control the Internet congestion. In order to meet a diversity of user access requirements, the IP (Internet Protocol) routers can provide users with various priority service classes. This paper explores the application of multi-agent systems (MAS) in the implementation...
Fault handling in Multi-Agent Systems (MAS) is not much addressed in current research. Normally, it is considered difficult to address in detail and often well covered by traditional methods, relying on the underlying communication and operating system. In this paper it is shown that this is not necessarily true, at least not with the assumptions on applications we have made. These assumptions are...
