Model-Based Engineering (MBE) is an approach to the design, analysis and development of software and systems that relies on exploiting high-level models and computer-based automation to achieve significant boosts in both productivity and quality. The ECMFA conference series is dedicated to advancing the state of knowledge and fostering the industrial application of MBE and related approaches. Its focus is on engaging the key figures of research and industry in a dialog which will result in stronger and more effective practical application of MBE, hence producing more reliable software based on state-of-the-art research results. ECMFA 2018 will be co-located with ICMT, TAP, SEFM, ICGT and TTC as part of the STAF federation of conferences, leading conferences on software technologies (STAF 2018). The joint organization of these prominent conferences provides a unique opportunity to gather practitioners and researchers interested in all aspects of software technology, and allow them to interact with each other.
