Model-Based Engineering (MBE) has proven to be highly successful in many different contexts in large software organizations such as Ericsson over the last decades. However, the broad adoption of MBE has been significantly limited by the fact that existing tools have failed to provide for better customizability and support for Domain-Specific Modeling Language (DSML) and to deliver capabilities ...

Satellite systems are becoming even more complex, making technical issues a significant cost driver. The increasing complexity of these systems makes requirements engineering activities both more important and more difficult. Additionally, todays competitive pressures and other market forces drive manufacturing companies to improve the efficiency with which they design and manufacture space pro...

For conceptual information analysis, the Object-Role Modeling (ORM) approach is arguably more suitable than Entity Relationship Modeling and the class modeling technique within the Unified Modeling Language. Although ORM has been used for three decades, and now has industrial modeling tool support, it has no official, standard metamodel. Because of its extensive capability for expressing busine...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...

Domain-specific modeling solutions have been promoted for some time in order to improve the productivity of software developers by providing them with modeling environments that are easier to learn, integrate best solutions and provide the possibility to automate software development by generating code from models. This paper presents experiences of developing a network modeling tool in Telefón...

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 Version 2.0 of our tool QPME (Queueing Petri net Modeling Environment) ...
