Model-Based Engineering (MBE) aims at increasing the effectiveness of engineering by using models as key artifacts in the development process. While empirical studies on the use and the effects of MBE in industry exist, there is only little work targeting the embedded systems domain. We contribute to the body of knowledge with a study on the use and the(More)
In many areas, such as automotive, healthcare, or production, we find software-intensive systems with complex real-time requirements. To efficiently ensure the quality of these systems, engineers require automated tools for the validation of the requirements throughout the development. This, however, requires that the requirements are specified in an(More)
In model-driven software engineering, model transformations are used for the specification of model changes. Similar to programs also model transformations can exhibit bad smells which indicate possible weaknesses. In this paper, we address bad smells which can negatively affect the performance of the application of model transformations, particularly ,(More)

Model-based engineering (MBE) aims at increasing the effectiveness of engineering by using models as important artifacts in the development process. While empirical studies on the use and the effects of MBE in industry exist, only few of them target the embedded systems domain.

—The selection of a suitable modelling language influences the success of software modelling. Several experiments comparing the comprehensibility of graphical modelling languages have been published. However, no published study comparing the comprehensibility of functional requirements modelled in different graphical modelling languages exists. This paper(More)
Along with technological developments and increasing competition there is a major incentive for companies to produce and market high quality products before their competitors. In order to conquer a bigger portion of the market share, companies have to ensure the quality of the product in a shorter time frame. To accomplish this task companies try to(More)
Model-driven software engineering in industrial practice has been the focus of different empirical studies and experience reports. Particularly, positive effects of model-driven software engineering have been reported in the domain of embedded and safety-critical systems. We report in this paper on the experiences of the openETCS European research project(More)
