FME 2003: Formal Methods

This volume contains the proceedings of FM 2003, the 12th International Formal Methods Europe Symposium which was held in Pisa, Italy on September 8 14, 2003. Formal Methods Europe (FME, www.fmeurope.org) is an independent association which aims to stimulate the use of and research on formal methods for system development. FME conferences began with a VDM Europe symposium in 1987. Since then, the meetings have grown and have been held about once every 18 months. Throughout the years the symposia have been notably successful in bringing together researchers, tool developers, vendors, and users, both from academia and from industry. Unlike previous symposia in the series, FM 2003 was not given a speci c theme. Rather, its main goal could be synthesized as widening the scope. Indeed, the organizers aimed at enlarging the audience and impact of the symposium along several directions. Dropping the su x E from the title of the conference re ects the wish to welcome participation and contribution from every country; also, contributions from outside the traditional Formal Methods community were solicited. The recent innovation of including an Industrial Day as an important part of the symposium shows the strong commitment to involve industrial people more and more within the Formal Methods community.
