Configuration logics: Modeling architecture styles

Joseph Sifakis, Simon Bliudze, Anastasia Mavridou, Eduard Baranov

We study a framework for the specification of architecture styles as families of architectures involving a common set of types of components and coordination mechanisms. The framework combines two logics: 1) interaction logics for the specification of arch ...

Functional BIP: Embedding connectors in functional programming languages

Romain Edelmann, Joseph Sifakis, Simon Bliudze

This paper presents a theoretical foundation for functional language implementations of Behaviour–Interaction–Priority (BIP). We introduce a set of connector combinators describing synchronisation, data transfer, priorities and dynamicity in a principled w ...

A Note on the Expressiveness of BIP

Simon Bliudze, Eduard Baranov

We extend our previous algebraic formalisation of the notion of component-based framework in order to formally define two forms, strong and weak, of the notion of full expressiveness. Our earlier result shows that the BIP (Behaviour-Interaction-Priority) f ...

Architecture Diagrams: A Graphical Language for Architecture Style Specification

Joseph Sifakis, Simon Bliudze, Anastasia Mavridou, Eduard Baranov

Architecture styles characterise families of architectures sharing common characteristics. We have recently proposed configuration logics for architecture style specification. In this paper, we study a graphical notation to enhance readability and easiness ...

Axo: Masking Delay Faults in Real-Time Control Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab, Maaz Mashood Mohiuddin

We consider real-time control systems that consist of a controller that computes and sends setpoints to be implemented in physical processes through process agents. We focus on systems that use commercial off-the-shelf hardware and software components. Set ...

Architecture-based Design: A Satellite On-board Software Case Study

Joseph Sifakis, Simon Bliudze, Anton Ivanov, Anastasia Mavridou

In this case study, we apply the architecture-based design approach to the control software of the CubETH satellite. Architectures are a means for ensuring global coordination properties and thus, achieving correctness of complex systems by construction. T ...

Axo: Tolerating Delay Faults in Real-Time Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab, Maaz Mashood Mohiuddin

We address delay faults: faults that cause a software component to take more time for completing an action than a given deadline. Such faults are particularly of interest in real- time mission-critical control applications that use general-purpose computin ...

A General Framework for Architecture Composability

Joseph Sifakis, Simon Bliudze, Eduard Baranov

Architectures depict design principles: paradigms that can be understood by all, allow thinking on a higher plane and avoiding low-level mistakes. They provide means for ensuring correctness by construction by enforcing global properties characterizing the ...

Parameterized Systems in BIP: Design and Model Checking

Joseph Sifakis, Simon Bliudze, Qiang Wang

BIP is a component-based framework for system design that has important industrial applications. BIP is built on three pillars: behavior, interaction, and priority. In this paper, we introduce first-order interaction logic (FOIL) that extends BIP to system ...
