Abstract: In Model-Driven Software Development, models are automatically processed to support the creation, build, and execution of systems. A large variety of dedicated model-transformation languages exists, promising to efficiently realize the automated processing of models. To investigate the actual benefit of using such specialized languages, we performed a large-scale controlled experiment in which ove...
Abstract: Growing software complexity is an increasing challenge for the software development of modern cyber-physical systems. A classical strategy for taming this complexity is to partition system behaviors into different operational modes specified at design time. Such a multi-mode system can change behavior by switching between modes at run-time. A complementary approach for reducing software complexity...
Abstract: Understanding the experiences of instructors teaching modelling and model-driven engineering is of great relevance to determining how MDE courses should be managed in terms of content, assessment, and teaching methods. In this paper, we report the results of a survey of 47 instructors in this field. Questions address course content, tools and technologies used, as well as positive and negative fac...
Abstract: Multimodal journey planners have been introduced with the goal to provide travellers with itineraries involving two or more means of transportation to go from one location to another within a city. Most of them take into account user preferences, their habits and are able to notify travellers with real time traffic information, delays, schedules update, etc.. To make urban mobility more sustainabl...
Abstract: Although there are many city journey planners already available in the market and involving various transportation services, there is none yet that allows city mobility operators and local government municipalities to be an active part of the city's mobility. In this demonstrator, we present our first attempt towards multi-view based modelling of adaptive and multimodal city journey planners. In p...
Abstract: Model-based Software Engineering (MBSE) is now accepted as a Software Engineering (SE) discipline and is being taught as part of more general SE curricula. However, an agreed core of concepts, mechanisms and practices --- which constitutes the Body of Knowledge of a discipline --- has not been captured anywhere, and is only partially covered by the SE Body of Knowledge (SWEBOK). With the goals of ...
Abstract: The purpose of this study is to provide understanding of project governance practices in agile projects. A systematic review of the previous agile literature is conducted to identify and categorize agile project governance practices, which are synthesized in a six-dimensional framework. The study contributes to the literature by contrasting traditional and agile project governance practices and by...
Abstract: In cyber-physical systems like automotive systems, there are components like sensors, actuators, and controllers that communicate asynchronously with each other. The computational model of actor supports modeling distributed asynchronously communicating systems. We propose Hybrid Rebeca language to support modeling of cyber-physical systems. Hybrid Rebeca is an extension of actor-based language Re...
Abstract: Abstract Large software companies need to support continuous and fast delivery of customer value both in the short and long term. However, this can be hindered if both the evolution and maintenance of existing systems are hampered by Technical Debt. Although a lot of theoretical work on Technical Debt has been produced recently, its practical management lacks empirical studies. In this paper, we i...
