So far, electronic data interchange (EDI) has been primarily used by large companies. They increasingly pressure their business partners to participate in or connect to their EDI infrastructure. Companies, which do not use EDI so far, face the challenge of imple-mentation. Questions, such as the choice of the right EDI approach and the right EDI standard, have to be answered. In addition, there are often high investment costs. Small- and medium-sized enterprises (SMEs) are particularly affected due to their limited re-sources and financial means in comparison to those of large enterprises. Based on a structured literature research, information on the state of the art as well as research was consolidated and the opportunities and risks of EDI for small and medium-sized enter-prises were examined. The results show that EDI offers a variety of opportunities ranging from process optimization to competitive advantages, but that these also depend on the degree of integration. The understanding of the own benefits as well as the support of the management plays an important role for the successful adoption, implementation and integration of EDI.
Keywords: EDI, interorganizational systems, SME, system integration, data interchange
Kurzfassung
Gegenstand der hier vorgestellten Arbeit ist die Untersuchung des Einflusses der Modellbildung auf die rechnerischen Ermüdungsnachweise orthotroper Fahrbahnplatten. Dazu wurde eine orthotrope Fahrbahnplatte, die den geltenden Konstruktionsempfehlungen entspricht, mit der Software SOFiSTiK als Stabwerksmodell, Stabwerksmodell mit Schalendeckblech (kombiniertes Modell) und FE-Modell modelliert. Anschließend wurden Ermüdungsnachweise mit den Ermüdungslastmodellen (ELM) 3 und 4 für zwei Konstruktionsbereiche berechnet.
Die Ergebnisse zeigen eindeutig, dass die Modellbildung Einfluss auf die Ergebnisse der Ermüdungsnachweise für die in dieser Arbeit ausgewählte Konstruktion hat. Für möglichst genaue und plausible Nachweisergebnisse ist die Anwendung des FE-Modells in Kombination mit dem ELM 4 zu empfehlen. Ein erster grober Überblick über die Ermüdung orthotroper Fahrbahnplatten kann jedoch mit allen Berechnungsmodelle und unter Anwendung von ELM 3 erzielt werden. Entgegen den normativen Vorgaben wird in An-betracht der Ergebnisse die Durchführung von Ermüdungsnachweisen auch für Neubauprojekte empfohlen.
Schlagwörter: Modellbildung, Ermüdungsnachweis, orthotrope Fahrbahnplatten, Brü-ckenbau
