ALPACAS: A Language for Parametric Assessment of Critical Architecture Safety (Artifact)

pdf-format:
DARTS-7-2-14.pdf (0.4 MB)

Abstract

This artifact contains a virtual machine allowing to use ALPACAS, a domain-specific language and algorithms aimed at architecture modeling and safety assessment for critical systems. ALPACAS allows to study the effects of random and systematic faults on complex critical systems and their reliability. The underlying semantic framework of the language is Stochastic Guarded Transition Systems, for which ALPACAS provides a feature-rich declarative modeling language and algorithms for symbolic analysis and Monte-Carlo simulation, allowing to compute safety indicators such as minimal cutsets and reliability. Built as a domain-specific language deeply embedded in Scala 3, ALPACAS offers generic modeling capabilities and type-safety unparalleled in other existing safety assessment frameworks. This improved expressive power allows to address complex system modeling tasks, such as formalizing the architectural design space of a critical function, and exploring it to identify the most reliable variant. The features and algorithms of ALPACAS are illustrated on a case study of a thrust allocation and power dispatch system for an electric vertical takeoff and landing aircraft.
