  This volume contains the proceedings of the Tenth Workshop on Quantitative
Aspects of Programming Languages (QAPL 2012), held in Tallin, Estonia, on March
31 and April 1, 2012. QAPL 2012 is a satellite event of the European Joint
Conferences on Theory and Practice of Software (ETAPS 2012). The workshop theme
is on quantitative aspects of computation. These aspects 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), and play an important (sometimes essential) role in
characterising the behavior and determining the properties of systems. Such
quantities are central to the definition of both the model of systems
(architecture, language design, semantics) and the methodologies and tools for
the analysis and verification of the systems 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.
