Software controls in technical systems are becoming more and more important and complex. Model based safety analysis can give provably correct and complete results, often in a fully automatic way. These methods can answer both logical and probabilistic questions. In common practice, the needed models must be specified in different input languages of different tools depending on the chosen verification tool for the desired aspect. This is time consuming and error-prone. To cope with this problem…

On Efficiently Specifying Models for Model Checking
TLDR
A method for reducing the state space by restructuring models by introducing as few additional states as possible by model design making state transitions more complex to avoid unreadability and infeasible model sizes is proposed.

TLDR
This paper presents some ideas and first steps towards an easy to learn and easy to use model based safety approach, and presents different user-interfaces that are supposed to support the user in his learning.
Qualitative and quantitative analysis of safety-critical systems with

’s expressive modeling language based on the programming language is introduced, showing how its fault modeling and flexible model composition capabilities can be used to model a case study from the transportation sector with multiple design variants.
Fault-Aware Modeling and Specification for Efficient Formal Safety Analysis
TLDR
A new fault modeling and specification approach for safety-critical systems based on the concept of fault activations that decreases explicit-state model checking and safety analysis times by up to three orders of magnitude is introduced.
A profile and tool for modelling safety information with design information in SysML
TLDR
A SysML profile designed for modelling the safety-related concerns of a system allows for greater consistency between safety information and system design information and can aid in communicating that information to stakeholders.

Unifying Probabilistic and Traditional Formal Model Based Analysis
TLDR
The experiences in designing a tool independent specification language (SAML) for model based safety analysis that allows to use only one model and analyze it with different methods and different verification engines, while guaranteeing the equivalence of the analyzed models.
A Framework for Qualitative and Quantitative Formal Model-Based Safety Analysis
TLDR
This paper proposes the SAML framework as a formal foundation for both qualitative and quantitative formal model-based safety analysis, and presents sound transformation of the formalism into two state of the art model-checking notations.

TLDR
This paper shows how one formal safety analysis method - Deductive Cause-Consequence Analysis (DCCA) - can be integrated in the SCADE framework, which allows for performing safety analysis largely automatically.

TLDR
The FSAP/NuSMV-SA platform is presented, based on the NuSMV2 model checker, that implements known and novel techniques to help safety engineers perform safety analysis and provides an environment that can be used both by design engineers to formally verify a system and by safety engineers to automate certain phases of safety assessment.
Probabilistic Model-Based Safety Analysis

This paper shows how functional models based on synchronous parallel semantics, which can be used for system design, implementation and qualitative safety analysis, can be directly re-used for (model-based) quantitative safety analysis.

This paper presents a systematic approach to formally model failure modes, and applies the method to a real world case study: a radio-based railroad crossing.
Probabilistic Model-Checking Support for FMEA
TLDR
This paper proposes a method for FMEA which makes use of probabilistic fault injection and Probabilistic model checking, and safety engineers are able to formally identify if a failure mode occurs with a probability higher than its tolerable hazard rate.
