MULTI-AGENT INFRASTRUCTURES FOR OBJECTIVE AND SUBJECTIVE COORDINATION

Coordination in multi-agented systems (MAS) can be conceived as either an agent activity (the subjective viewpoint) or an activity over agents (the objective viewpoint). The two viewpoints have generated two diverging and often contrasting lines of research, as well as different and noncompatible technologies, however, their integration is mandatory for modeling and engineering complex MAS. In this paper, we explore the issue of integration at both the model and the technology levels.

First, by taking FIPA agents and coordination artifacts as reference notions for subjective and objective approaches, respectively, we sketch a framework where agent interactions with coordination artifacts are modeled as physical acts, deliberated and executed by agents analogously to communicative actions. Then, we show how the JADE infrastructure for FIPA-compliant agents, and the TuCSoN infrastructure providing agents with coordination artifacts can be integrated at the technology level, allowing JADE agents to access TuCSoN tuple centers through JADE services.     

DYNAMIC FUZZY OWA MODEL FOR EVALUATING THE RISKS OF SOFTWARE DEVELOPMENT

How to get the relative weights in multiple criteria decision making (MCDM) problems is an important issue. In 1988, Yager proposed an ordered weighted averaging (OWA) aggregation method to find the related weights of many criteria. However, the previous aggregation operators (including OWA) and the aggregation situation are independent. For solving the problem, we propose a new aggregation situation and operator model—a dynamic fuzzy OWA model based on the evaluating situation. The OWA can modify associated weights dynamically based on the aggregation situation and work like a “magnifying lens” to enlarge and find the most important attribute dependent on the minimal information, or get equal attributes' weights based on maximal information. We also evaluate the risks of software development and compare the results with Chen's (2001 Chen , S. M. 2001 . Fuzzy group decision making for evaluating the rate of aggregative risk in software development . Fuzzy Sets and Systems , 118 : 75 – 88 .[Crossref], [Web of Science ®] , [Google Scholar]) and Lee's (1996 Lee , H. M. 1996 . Group decision making using fuzzy sets theory for evaluating the rate of aggregative risk in software development . Fuzzy Sets and Systems , 80 : 261 – 271 .[Crossref], [Web of Science ®] , [Google Scholar]) methods.

COMPONENT-BASED MODELS AND SIMULATIONS FOR SUPPORTING VALID MULTI-AGENT SYSTEM SIMULATIONS

The more simulation becomes an established tool in the design of multi-agent systems, the more urgent the question becomes how valid the induced properties and behavior patterns are. Answering this question depends on the validity of the models, the correctness of the simulators, and the simulations. In all of these aspects, reuse and a declarative representation plays a crucial role. With James II, we developed a customizable framework for modeling and simulation. Its component-based architecture supports a reuse of models, simulators, and experimental settings. The benefits of this architecture for agent-based modeling and simulation will be illuminated by an excerpt of a simulation study about trading strategies for mobile ad hoc networks.     

SOFTWARE TOOLS FOR MULTIPROCESSOR SIMULATION AND PROGRAMMING

ABSTRACT

Array C Language (ACLAN) is a programming language that extends C by endowing it with structures for programming array processors. ACLAN's two salient features are its machine independence and its ability to handle local processing element memory directly. This article describes ACLAN additions to C, Research in parallel programming with ACLAN is supported by Array C Language Emulator (ACLE), a software package comprising an ACLAN-to-C translator, a library of simulations routines, and array processor specification software. ACLE enables the execution of programs written in ACLAN to be simulated on a conventional sequential computer. Finally, an algorithmic solution for mapping algorithms on hypercube computers is provided.

MULTI-AGENT INTELLIGENT PLANNING ARCHITECTURE FOR PEOPLE LOCATION AND ORIENTATION USING RFID

The new advances in information communications technology (ICT) allow expanding the electronic communication networks into an objective environment. These techniques can be used to help users who have to go to a building with several floors, corridors, and departments to get its right location and orientation. The problem gets more complicated when there are a high number of visitors with temporal constraints. Typically the lack of information and signs to guide the user complicates this task. A typical example is a hospital, where patients have scheduled doctor's appointments and in some cases movement problems (handicaps). A possibility for solving this problem is to equip the building with an intelligent system for user detection and orientation.

In this article we present a solution that uses a detection and a location system based on wireless technology and artificial intelligence techniques to plan and inform about the paths the user can follow.

DEVISING A TRUST MODEL FOR MULTI-AGENT INTERACTIONS USING CONFIDENCE AND REPUTATION

In open environments in which autonomous agents can break contracts, computational models of trust have an important role to play in determining who to interact with and how interactions unfold. To this end, we develop such a trust model, based on confidence and reputation, and show how it can be concretely applied, using fuzzy sets, to guide agents in evaluating past interactions and in establishing new contracts with one another.
