Model comparison is an important challenge in model-driven engineering, with many application areas such as model versioning and domain model recovery. There are numerous techniques that address this challenge in the literature, ranging from graph-based to linguistic ones. Most of these involve pairwise comparison, which might work, e.g. for model versioning with a small number of models to consider...
A challenging aspect of model-to-code transformations is to ensure that the semantic behavior of the input model is preserved in the output code. When constructing concurrent systems, this is mainly difficult due to the non-deterministic potential interaction between threads. In this paper, we consider this issue for a framework that implements a transformation chain from models expressed in the state...
In order to show that the required safety objectives are met, it is necessary to collect safety evidence in the form of consistent and complete data. However, manual safety evidence collection is usually tedious and time-consuming, due to a large number of artifacts and implicit relations between them. The potential ambiguities in the textual description of safety objectives even increase the difficulties...
We present an approach to model hardware configurations of complex manufacturing systems such as ASML's lithography machines. These hardware configurations consist of actuator and sensor elements which are controlled by system software that consists of over 35 million lines of code. To minimize the cost of testing and system integration, software simulators of hardware configurations are used -- acting...
An Enterprise Java Beans (EJB) interceptor is a software mechanism that provides for introducing behavior implemented as separate code into the execution of a Java application. In this way EJB interceptors provide a clear separation of the core functionality of the bean and other concerns, such as logging or performance analysis. Despite the beauty of the idea behind the interceptors, developing,...
