CALL FOR PAPERS Seventh Workshop on Quantitative Aspects of Programming Languages (QAPL 2009) Affiliated with ETAPS 2009 March 28-29, 2009, York, UK


Quantitative aspects of computation are important and sometimes essential in characterising the behavior and determining the properties of systems. They are related to the use of physical quantities (storage space, time, bandwidth, etc.) as well as mathematical quantities (e.g. probability and measures for reliability, security and trust). Such quantities play a central role in defining both the model of systems (architecture, language design, semantics) and the methodologies and tools for the analysis and verification of system properties. The aim of this workshop is to discuss the explicit use of quantitative information such as time and probabilities either directly in the model or as a tool for the analysis of systems. In particular, the workshop focuses on:

  • the design of probabilistic, real-time, quantum languages and the definition of semantical models for such languages
  • the discussion of methodologies for the analysis of probabilistic and timing properties (e.g. security, safety, schedulability) and of other quantifiable properties such as reliability (for hardware components), trustworthiness (in information security) and resource usage (e.g., worst-case memory/stack/cache requirements)
  • the probabilistic analysis of systems which do not explicitly incorporate quantitative aspects (e.g. performance, reliability and risk analysis)
  • applications to safety-critical systems, communication protocols, control systems, asynchronous hardware, and to any other domain involving quantitative issues


Topics include (but are not limited to) probabilistic, timing and general quantitative aspects in: Language design, Information systems, Asynchronous HW analysis, Language extension, Multi-tasking systems, Automated reasoning, Language expressiveness, Logic, Verification, Quantum languages, Semantics, Testing, Time-critical systems, Performance analysis, Safety, Embedded systems, Program analysis, Risk and hazard analysis, Coordination models, Protocol analysis, Scheduling theory, Distributed systems, Model-checking, Security, Biological systems, Concurrent systems, ...

Invited Speaker

  • Vincent Danos, Universite Paris Diderot - Paris 7, France.
  • Jane Hillston, University of Edinburgh, UK.


In order to encourage participation and discussion, this workshop solicits two types of submissions - regular papers and presentations:

1. Regular paper submissions must be original work, and must not have been previously published, nor be under consideration for publication elsewhere. Regular paper submission must not exceed 15 pages, possibly followed by a clearly marked appendix which will be removed for the proceedings and contains technical material for the reviewers.

2. A presentation reports on recent or ongoing work on relevant topics and ideas, for timely discussion and feedback at the workshop. There is no restriction as for previous/future publication of the contents of a presentation. Typically, a presentation is based on a paper which recently appeared (or which is going to appear) in the proceedings of another recognized conference, or which has not yet been submitted. The (extended) abstract of presentation submissions should not exceed 4 pages.

All submissions must be in PDF format and use the ENTCS style files. Submissions can be made on the following website: The program co-chairs can be contacted at: The workshop PC will review all submissions of both types to select appropriate ones for acceptance in each category, based on their relevance, merit, originality, and technical content. The authors of the accepted submissions of both types are expected to present and discuss their work at the workshop. Accepted regular papers will be published in Elsevier's ENTCS. Publication of a selection of the papers in a special issue of a journal is under consideration.

For regular papers: Submission (title + abstract): December 18, 2008 Submission (regular paper): December 20, 2008 Notification: January 28, 2009 Final version (ETAPS proceedings): February 2, 2009 Final version (ENTCS proceedings): TBA

For presentations: Submission: January 28, 2009. Notification: January 31, 2009.
