In this study, an Agent-Based Collaborative Scheduling System is represented as a model of scheduling among shops. Agent-based system describes the behaviors of distributed decision maker agents in manufacturing systems. Agents in the system are Production Planning Agent and Shop-Floor Agents. Shop-Floor Agents are semi-autonomous agents so that the degree of autonomy is determined by the Production Planning Agent. The distributed system forming heterogeneous units was designed by hybrid control architecture. The study focuses on constructing an Agent-Based Collaborative Scheduling System that is capable of conducting scheduling negotiations among shop-floor agents. The designed system is capable of scheduling by considering heterogeneous objectives of the shop-floor agents within a collaborative manufacturing environment. Negotiation is co-operative not competitive. Shop-Floor Agents generates collaboratively their schedules. The schedule for the best interest of the system as a whole is selected by the Production Planning Agent. [ABSTRACT FROM AUTHOR]

A social network, in which nodes represent humans and weighted ties reflect relationships between them, can be formed in an automatic way based on the data about customers of a telecommunication company as well as their communication activities. The expansion of a telecommunication social network can be supported with one of three main approaches that have been considered in this paper: existing group conjunction, internal expansion of groups, and transfer of external relationships.

In the Architecture Engineering and Construction sector (AEC) cooperation between actors is essential for project success. The configuration of actors' organization takes different forms like the associated coordination mechanisms. Our approach consists in analyzing these coordination mechanisms through the identification of the "base practices" realized by the actors of a construction project to cooperate. We also try with practitioners to highlight the "best practices" of cooperation. Then we suggest here two prototypes of IT services aiming to demonstrate the value added of IT to support cooperation. These prototype tools allow us to sensitize the actors through terrain experiments and then to bring inch by inch the Luxembourgish AEC sector towards electronic cooperation. [ABSTRACT FROM AUTHOR]

Experience shows that testing students' understanding of new concepts immediately after they have been introduced considerably improves the learning process. In this work understanding of a concept is assumed to take place if a student can provide reasonably correct answers to questions requiring application this concept. A possible solution to the problem of how to determine whether students actually understand a concept is to give them tests. Such tests, being a part of an intelligent system, provide inconsistent information to intelligent agents, facilitating the tests evaluation process. This happens because the degree of a student's understanding varies a lot depending on factors like time and the way questions are formulated. Since classical logic fails to draw conclusions in the presence of inconsistencies we propose application of paraconsistent logic. [ABSTRACT FROM AUTHOR]

The paper is devoted to application of formal concept analysis and collaborative design in shipbuilding. Sourcing and shoring strategies of a Norwegian multinational design company is illustrated by a concept lattice. [ABSTRACT FROM AUTHOR]

Recently an integrated multiplatform system aiming at offering travel service over several communication channels is under development. A set of cooperating systems in completely different platforms will work together to provide integrated services to the clients anywhere and anytime. The structure, communication environment, some special issues and implementation of the system are discussed in the paper. [ABSTRACT FROM AUTHOR]
