AutomationML is an emerging IEC standard for storing and exchanging engineering data among the heterogeneous software tools involved in the engineering of production systems. One important subset of such engineering data is the plant behavior. To make this data exchangeable, AutomationML uses the existing industry data format PLCopen XML. However, at the development stages of production systems...

Design patterns and frameworks have become important concepts in object development. As well important is UML as the standard modeling language. But there is not sufficient support to model design patterns and frameworks in design class diagrams (DCDs) without using the extension mechanisms, that is, stereotypes, constraints, and tagged values. Some approaches have been developed to improve the...

In the paper we propose an approach for the construction of meta-CASE workbenches. The approach is based on the technology of visual language generation systems and on UML meta modeling. Visual modeling environments are generated starting from UML class diagrams specifying abstract syntax of the underlying visual language. The meta-CASE generates a workbench by integrating a set of visual model...

Acceleration of product development, decrease of NC programming effort and increase of product quality are demands from enterprises to make their products competitive. These requirements are hardly met by the today’s used CAx process chain which is based on a multitude of interfaces and the standardized control data format ISO 6983. New concepts of product data modelling are necessary for a str...

a r t i c l e i n f o In recent years many simulation-based serious games have been developed for supporting (future) managers in operations management decision making. They illustrate the high potential of using discrete event simulation for pedagogical purposes. Unfortunately, this potential does not seem to go together with the availability of guidance for the game designer on the use of sim...

Constructing structurally complex reservoir models at the appraisal stage is a complex task, with a high-degree of uncertainty. The lack of an intuitive set of modeling and visualization tools that support expert visual interpretation from geophysicists and geologists significantly increases the challenge. We present a set of interactive software tools to reservoir modeling in the appraisal sta...

The automatic layout of software diagrams is a very attractive graph drawing application for use in software tools. Object-oriented software may be modelled using a visual language called the Uniied Modeling Language (UML). In this paper we present an algorithm for the automatic layout of UML class diagrams using an extension of the Sugiyama algorithm together with orthogonal drawing. These dia...

Although modeling languages as the UML (Unified Modeling Language) are primarily used in the context of software development, other application scenarios exist. A prominent example is the definition of languages; e.g. UML is partly defined in terms of UML. This technique of metamodeling became popular and has many advantages, but metacircularity is one of the most serious disadvantages. This pa...

Visual languages are important in software engineering. However , the speciication and implementation of visual languages in software tools is still an immature area. In this paper, we present Vilpert which is an object-oriented framework for implementing visual languages in Java. Implementing a visual language with Vilpert means deriving a language analyzer based on a formal syntactic speciica...

The UML allows us to specify models in a precise, complete and unambiguous manner. In particular, the UML addresses the specification of all important decisions regarding analysis, design and implementation. Although UML is not a visual programming language, its models can be directly connected to a vast variety of programming languages. This enables a dual approach to software development: the...
