Integrated Formal Methods

This book constitutes the refereed proceedings of the 7th International Conference on Integrated Formal Methods, IFM 2009, held in Düsseldorf, Germany in February 2009. The 21 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 55 submissions. The papers address the whole spectrum of integrated formal methods, ranging from formal and semiformal modelling notations, semantics, verification, refinement, model transformations to type systems, logics, tools and case studies.
