Organisation models are at the core of enterprise model, since they represent key aspects of a company's action system. Within MEMO, the Organisation Modelling Language (OrgML) supports the construction of organisation models. They can be divided into two main abstractions: a static abstraction...

An enterprise model comprises various abstractions of an enterprise that represent both information systems and the surrounding action systems. These different models are integrated in order to avoid redundant work and to contribute to a tight and consistent integration of action systems and...

In recent years, the development of domain-specific modelling languages has gained remarkable attention. This is for good reasons: A domain-specific modelling language incorporates concepts that represent domain-level knowledge. Hence, systems analysts are not forced to reconstruct these...

Today wireless network connections gain more and more importance. Yet a drawback of this technology is the higher packet error rate compared to wired networks. This has a negative impact on SCTP associations as packet loss is considered a congestion indication. The SCTP extension PKTDROP reacts...

While it is widely agreed that current enterprise resource planning (ERP) systems cannot evolve much further, it is the question how future enterprise systems will look like. To approach an answer to this question, this report provides at first an analysis of essential high level requirements...
