Probabilistic Deadline Miss Analysis of Real-Time Systems Using Regenerative Transient Analysis

Laura Carnevali, Alessandra Melani, Luca Santinelli, Giuseppe Lipari
2014 Proceedings of the 22nd International Conference on Real-Time Networks and Systems - RTNS '14  
Evaluation is performed through regenerative transient analysis based on the method of stochastic state classes, supporting the derivation of quantitative measures on the time by which a deadline is missed  ...  Real-time systems, probabilistic schedulability analysis, probabilistic Worst Case Execution Time (pWCET), Extreme Value Theory (EVT), non-Markovian stochastic analysis.  ...  The pWCETs found as output will be then used to perform probabilistic schedulability analysis through regenerative transient analysis [24] .  ...

A Survey of Probabilistic Schedulability Analysis Techniques for Real-Time Systems

Robert I. Davis, Liliana Cucu-Grosjean
2018 Leibniz Transactions on Embedded Systems  
This survey covers schedulability analysis techniques for probabilistic real-time systems.  ...  It provides a taxonomy of the different methods used, and a classification of existing research.  ...  This enables regenerative transient analysis based on stochastic state classes to be used to compute the probability that each task misses a deadline within a time t.  ...

A New Approach to the Evaluation of Non Markovian Stochastic Petri Nets [chapter]

Serge Haddad, Lynda Mokdad, Patrice Moreaux
2006 Lecture Notes in Computer Science  
In this work, we address the problem of transient and steadystate analysis of a stochastic Petri net which includes non Markovian distributions with a finite support but without any additional constraint  ...  Using Petri nets as the modelling formalism enables us to express the behaviour of the approximate process by tensorial expressions.  ...  Another application area of our method is the real-time systems domain. Such systems are often composed by periodic tasks and sporadic tasks both with deadlines.  ...

A framework for rare event simulation of stochastic Petri nets using "RESTART"

Christian Kelling
1996 Proceedings of the 28th conference on Winter simulation - WSC '96  
For the performability evaluation of complex systems simulation remains often the only feasible method.  ...  Unfortunately, simulation experiments tend to be very time consuming if rare events have to be considered.  ...  ACKNOWLEDGEMENTS I am thankful to my students Patrick Drescher and Henning Ziegler who implemented the RESTART techniques and did patiently most of the simulation experiments.  ...

On the Quality of Service of Crash-Recovery Failure Detectors

Tiejun Ma, Jane Hillston, Stuart Anderson
2007 37th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN'07)  
on an approximate probabilistic model of the two-process failure detection system.  ...  We show that the fail-free run and the crash-stop run are special cases of the crash-recovery run with mean time to failure (MTTF) approaching to infinity and mean time to recovery (MTTR) approaching to  ...  The detection of timing failure should be based on the specified deadline or time constraints.  ...
