MODELS is the premier venue for the exchange of innovative ideas and experiences of model-based approaches in the development of complex systems. Since 1998, MODELS has provided a broad forum for reporting scientific progress as well as experiences stemming from practical application of model-based methods. MODELS is a highly selective conference, with an acceptance rate averaging twenty per cent in recent years.

The conference series covers all aspects of model-based development for software and systems engineering, including modeling languages, methods, tools, and their applications. Engineering models have long been used in the development of complex systems and the approach is becoming more prevalent in the design of modern software systems.

The theme for MODELS 2011 is Modeling in 2020. The theme has been selected to encourage fresh thinking about the future role of modeling in complex systems engineering. We would like to encourage ‘outside the box’ thinking; to this end, MODELS 2011 solicits, in addition to the usual foundations and applications papers, special vision papers as part of the Foundations Track (see below). We also particularly welcome submissions with an interdisciplinary perspective.

The 2011 conference has two distinct tracks:

- Foundations track
- Applications track

Papers in each track will be evaluated by separate program committees based on criteria appropriate to that track. All accepted papers in both the Foundations and Applications tracks will be published as a single conference proceedings in the Lecture Notes in Computer Science. Calls for workshops, tutorials, educators and doctoral symposium are also available from http://www.modelsconference.org
