Abstract

Assuring safety and reliability is fundamental when developing a safety critical system. Road, naval and avionic transportation; water and gas distribution; nuclear, eolic, and photovoltaic energy production are only some examples where it is mandatory to guarantee those properties. The continuous increasing in the design complexity of safety critical system calls for a never ending sought of new and more advanced analytical techniques. In fact, they are required to assure that undesired consequences are highly improbable. In this Thesis we introduce a novel methodology able to raise the bar in the area of automated safety and reliability analysis. The proposed approach integrates a series of techniques, based on symbolic model checking, into the current development process of safety critical systems. Moreover, our methodology and the resulting techniques are thereafter applied to a series of real-world case studies, developed in collaboration with authoritative entities such as NASA and the Boeing Company.
