Enterprise Architecture (EA) requires modeling enterprises across multiple levels (from markets down to IT systems) – i.e. modeling hierarchical systems. Our goal is to build a Computer Aided Design (CAD) tool for EA. To be able to build this CAD tool, we need an ontology that can be used to describe hierarchical systems. The Reference Model of Open Distributed Processing (RM-ODP) was originall...

The paper describes a conceptual framework for model-driven development based on a concise application of UML and modeling tool functionality. A case study of modeling software for library management is presented as an illustration of how to apply the proposed framework. Modeling tool features such as model transformations, code generation cartridges, model validation, dependency matrix, model ...

The bflow* Toolbox is a modeling tool for the business process modeling language Event Driven Process Chains (EPCs). In this paper, we describe three innovative features of the modeling tool: First, the modeler gets continuously feedback about possible modeling problems. Second, there is an option to construct a large part of a model with input from the keyboard only, i.e. without ever touching...

Queueing Petri nets are a powerful formalism that can be exploited for modeling distributed systems and analyzing their performance and scalability. By combining the modeling power and expressiveness of queueing networks and stochastic Petri nets, queueing Petri nets provide a number of advantages. In this paper, we present our tool QPME (Queueing Petri net Modeling Environment) for modeling an...

Nowadays there are powerful tools for Domain-Specific Modeling. An ongoing problem is the insufficient tool interoperability which complicates the development of complete tool chains or the re-use of existing metamodels, models, and model operations. In this paper we present the approach of M3-Level-Based Bridges and apply this approach to enable the interoperability between two selected tools....

This paper presents the application of iSight for optimal tip design of complex tool holder spindle. The complex tool holder is used for holding a (milling/drilling) tool of a machine tool. The engineering problem of complex tool holder results from the twisting of spindle of tool holder. This leads to the vibration of tool holder which makes the tool holder malfunction. This engineering proble...

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

Tight time and cost constraints force chemical process industries to continuously reduce their experimental effort during chemical process development and to facilitate the application of model-based process technology. Nevertheless, the effort of setting up a detailed mathematical model for a chemical process remains still high due to the large variety of chemical process units and physical ph...

Most of the time developers make extensive use of software tools in a software development process to support them in their day-to-day work. One of the first and most important phases of this process is the design phase, but within this phase intuitive and easy to use tools, which support the creative but also collaborative workflow (parallel/distributed), are missing. At the moment, developers...

Mechatronic systems abound in technological fields such as robotics and machine tools industry. Significant advances in dynamic performance of these systems can be achieved provided that mutual interactions of different domains (such as mechanics, electronics, hydraulics and control) are thoroughly understood. Virtual prototyping entails integration of multi-domain dynamic simulation in the des...
