First International workshop on Validation and Verification of Dynamic Software Systems ViDaS' 10 (Paris, France, from 2010-04-06 10:00 to 2010-04-10 20:15) — by Nelly Bencomo

Increasingly software systems are required to survive fluctuations in their execution environment without or with only little human intervention. These modern and complex systems cannot be shutdown to be changed or updated and restarted again. Instead, these systems need to be change-enabled to fluidly reconfigure and adapt to the ongoing circumstances and to find the way to continue accomplishing their goals. Such systems, called dynamic software systems (DSS), play vital roles in society’s infrastructures. The demand for DSS appears in application domains spanning business applications (e.g., virtual organizations and dynamic service compositions), entertainment, such as mobile interactive, and also safety critical systems, such as crisis and disaster management applications, space exploration, and transportation domains among others. Different international research initiatives and projects have started creating awareness and producing initial results in the development of technologies and platforms for such systems. Nevertheless, the dynamic nature of these systems still poses challenging research questions about how to guarantee their validity and correctness, especially in the case of safety critical applications. For instance, are traditional Validation and Verification (V&V) techniques usable in this new scenario? If so, how can they be reused? Given the new circumstances, new V&V techniques must also be explored. Such techniques should exploit the dynamic nature of DSS to provide for instance, V&V at runtime. The goal of this workshop is to bring together practitioners and researchers to identify and discuss the major research questions that emerge when tackling the validation and verification of dynamic software systems. Some of these questions are: How to ensure that the dynamic changes in the running system are performed correctly? How to ensure that the changes in the system are correct? (e.g. with respect to the requirements) How to ensure that the reconfigurations yield a system whose functional and extra-functional characteristics satisfy the requirements? How to ensure that the changes will be performed when needed? Which of the existing V&V techniques can help dealing with the V&V issues of dynamic software? How can these techniques be applied in this context? What are the differences between V&V done during design and runtime? How new V&V techniques performed at runtime challenge or modify the assumptions of current techniques?
