This book constitutes the refereed proceedings of the Third International Workshop on Formal Techniques for Safety-Critical Systems, FTSCS 2014, held in Luxembourg, in November 2014. The papers address various topics related to the application of formal and semi-formal methods to improve the quality of safety-critical computer systems.

Case studies and experience reports on the use of formal methods for analyzing.- Safety-critical systems.- Methods, techniques, and tools to support automated analysis, certifcation, and debugging of complex safety/QoS-critical systems.- Analysis methods that address the limitations of formal methods in industry.- Formal analysis support for modeling languages used in industry.- Code generation from validated models.- Methods, techniques, and tools to support automated analysis, certifcation, and debugging of complex safety/QoS-critical systems.- Analysis methods that address the limitations of formal methods in industry.- Formal analysis support for modeling languages used in industry.- Code generation from validated models.
