This book constitutes the thoroughly refereed post-workshop proceedings of the 12th International Workshop on Formal Methods for Industrial Critical Systems, FMICS 2007, held in Berlin, Germany, in July 2007 - colocated with CAV 2007, the 19th International Conference on Computer Aided Verification. The 15 revised full papers presented together with the abstracts of 2 invited lectures were carefully selected during two rounds of reviewing and improvement from 31 initial submissions. The papers strive to promote research and development for the improvement of formal methods and tools for industrial applications and they are organized in topical sections on control systems, scheduling and time, verification, software, and testing.
