IMPACTS OF INFORMATION TECHNOLOGY USE IN BUSINESS SUPPORT AGENCIES SERVICES

Abstract New technologies like the Internet offer many possibilities of work and life, e.g. new knowledge-based applications in economy. Beside the advantages of applications of the new technologies also negative consequences appear when using the Internet and different “virtual forms” of work, learning and social life. This paper deals with aspects of the Internet use and with a project about the development of new integrated concepts for (regional and local) economic development, by Internet-based knowledge processing and learning in business support agencies (BSA) in Germany.

Improving Continuous Vocational E-Training

Abstract E-training, particularly based on the Internet and the Web, seems to be an innovative form of qualification in organisations. It supports processes of knowledge acquisition and transfer as well as life-long learning. In many cases the implementation of e-training within continuous vocational qualification is not successful. Based on their experience within national and European projects, the authors of this paper present some proposals for improving continuous vocational e-training and give examples.

Cooperative work with an intranet communication toolkit

Nowadays new forms of cooperation are developing in connection with computer networking like cooperation between decentralised units of a company or virtual companies. An important problem within distributed computer systems is the group communication. This paper reports on the TGC system, which provide a flexible group communication model to application developers. For the TGC system, three architectures were designed, implemented and tested at University of Craiova, Romania.

The TGC system is implemented on an Ethernet network of DEC 3000 station under OSF/1 and Zenith PC under Linux and Windows NT. The TGC system is the result of the cooperation between IAT Research Center (Germany) and University of Craiova, Department of Computer Science (Romania) in the European TEMPUS Program. This paper presents the three implementations of the TGC system. We discuss the system architectures, the primitives for multicast communication and we compare the results of the three architectures.

Improving Cooperation in E-Commerce by Integrated Data Mining Methods in Web-Environments

Abstract In order to improve the quality of decisions and the cooperation with clients and other partners. methods of acquisition. structuring and analysis of knowledge based on database reverse engineering techniques and data mining can be integrated into environments like the Web-sites. In this paper some work within a European ongoing project with this topic is described.

Real Time Environmental Monitoring Centre

ABSTRACT In this paper some results of European projects about the data acquisition systems, modelling of environment pollution by developing environmental regional monitoring centres which comply with regulatory requirements and protect public health are presented. The heart of each centre is a real time system for monitoring and detection of noxis, for prognosis and assisted decisions based on information about factors of industrial risks and meteorological conditions. The system will use fuzzy methods and neural networks for decisions and data mining for data analysis. The development of the centres is done within two EU-cooperation projects: the !NCOT and the MONITOR and they will be used by the Agencies of Civil Protection and Environment Protection in Romania in the regions Oltenia, Iasi, Arges.

A Flexible, User-Friendly Communication Structure for Engineering Applications

Abstract Cooperative acting and communicating in project teams by using distributed applications and knowledge resources could help manufacturing companies to be competitive. In this paper an example of a CORBA-based communication structure between different applications for an environmentally-friendly design of machine tools which has been developed as a part of an EU-TEMPUS-Collaboration between the IAT Germany and the University of Craiova, Romania, is described.

New Ways of Product Development in the German Industry and the Role of New Information Technologies

Abstract In this paper some weak points of product development processes in the German industry are presented as a result of the analysis earned out in 500 German manufacturing companies within the nation-wide programme “Produktion 2000” as well as innovative ways to improve these weak points. Such ways are illustrated by three examples: the first one is a successful cooperative development of a product, the second one reflects findings about computer applications supporting organizational change and the third one is an IT-tool for cooperative management and control over projects in and between manufacturing companies.

Ein Softwarewerkzeug für Multicast-Kommunikation im Rahmen neuer Formen der Kooperation

Heutzutage entwickeln sich neue Formen der Kooperation in Verbindung mit Computernetzwerken sowohl zw. dezentralisierten Einheiten einer Organisation als auch zw. versch. Unternehmen wie die virtuellen Unternehmen. Die Zusammenarbeit ist in diesen Formen zeitlich und raumlich (lokal oder global) verteilt: die Kooperationspartner arbeiten zumeist in Projektteams. Auser den Computernetzwerken brauchen die Partner verteilte Systeme, die ihre Arbeit und Kommunikation zu verschiedenen Zeiten und an unterschiedlichen Orten unterstutzen. Haufig involviert diese Kommunikation mehrere Partner (Prozesse) und nicht nur zwei wie in den klassischen Client-Server-Modellen. Die Teams sind dynamisch, eine Person kann Mitglied mehrerer Teams sein. Die Implementierung der verteilten Systeme hangt von mehreren Faktoren, z.B. von den Netzeigenschaften ab. In einigen Netzwerken ist es moglich, eine spezielle Netzwerkadresse zu kreieren; wenn eine Nachricht zu einer dieser Adressen geschickt wird, dann ist sie automatisch an alle Prozesse die sich mit dieser Adresse sich unterhalten (Multicast) gesendet. Andere Netzwerke besitzen Broadcast- oder Unicast-Einrichtungen. Auch die Natur der unterstutzten Teamprozesse (offen oder geschlossen bzw. hierarchisch oder nicht hierarchisch) beeinflussen die Implementierung.

An Example of an Object-Oriented Tool for Transactions in the First Phase of Product Development

Abstract This paper presents an experimental object oriented system that provides operating system level support for distributed atomic transactions that operate on share objects. Atomic transactions are a common construct that distributed programming environments provide in order to maintain the consistency of distributed information in the presence of partial failure and concurrency. The paper presents the basic components of a distributed object oriented system based on transactions processing (DOSTP system) and its implementation on a local network of DEC Stations 3000 under OSF/l vers 1.32 Zenith PC under Linux 2.0 and Windows NT 4.0 and on a Novell network under Netware 3.11. Basic transport-level communication is performed by TCP/IP via an Ethernet and by IPX, respectively.

Beispiele für arbeitsorientierte Benutzungs-oberflächen von DV-Systemen für Ingenieuraufgaben

Das Spektrum von Ingenieuraufgaben, die durch Computer unterstutzt werden, wird immer breiter, die benutzten Softwaretechniken immer komplizierter. Die wachsende Komplexitat und oftmals unangemessene Funktionalitat reduziert die Durchschaubarkeit der Systeme und erschweren ihren Gebrauch. Die damit auftretenden Schwierigkeiten durfen aber den Benutzer nicht uberfordern. Der Softwareingenieur mus daher das unterstutzende System als “Werkzeug” gestalten, mit dem der Benutzer seine Aufgabe effizient und auch ohne vertiefte DV-Kenntnisse losen kann.
