Modeling and Analysis of the Landing Gear System with the Generalized Contracts [article]

Abdelkader Khouass and christian attiogbé and mohamed messabihi
2022 arXiv   pre-print
This paper describes how the Minarets method decreases the difficulty of modeling, composition and analysis of the well known case study of the landing gear system.  ...  The modeling, assembly and analysis of such open and complex heterogeneous systems are challenges in software engineering.  ...  If we focus on the analysis of the various properties, we remark that the safety, time and liveness properties were formalized and proved, but from our point of view the analysis of time and liveness properties  ...

The Unit-B method: refinement guided by progress concerns

Simon Hudon, Thai Son Hoang, Jonathan S. Ostroff
2015 Journal of Software and Systems Modeling  
Unit-B aims at the stepwise design of software systems satisfying safety and liveness properties.  ...  Based on events schedules, we propose proof rules to reason about progress properties and a refinement order preserving both liveness and safety properties.  ...  According to a survey [8] , liveness properties (in terms of existence and progress) amount to 45% of the overall system properties.  ...

An intruder model for verifying liveness in security protocols

Jan Cederquist, Mohammad Torabi Dashti
2006 Proceedings of the fourth ACM workshop on Formal methods in security - FMSE '06  
We present a process algebraic intruder model for verifying a class of liveness properties of security protocols.  ...  These protocols all aim at a liveness requirement, namely fair exchange of valuable electronic items (money, signature, evidence etc).  ...  Safety, Liveness and the DY Intruder Properties of systems can usually be divided into two classes: safety properties (something bad will never happen) and liveness properties (something good will eventually  ...

Composition for component-based modeling

Gregor Gössler, Joseph Sifakis
2005 Science of Computer Programming  
We propose results ensuring correctness by construction of a system from properties of its interaction model and of its components.  ...  Nevertheless, flexible composition is a partial operation. Product systems should be interaction safe in the sense that they do not violate constraints of the interaction model.  ...  such as deadlock-freedom and liveness.  ...
