Rely/Guarantee Reasoning for Teleo-reactive Programs over Multiple Time Bands

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNPSE,volume 7321))

Abstract

A complex real-time system consists of components at multiple time abstractions with varying notions of granularity and precision. Existing hybrid frameworks only allow reasoning at a single granularity and at an absolute level of precision, which can be problematic because the models that are developed can become unimplementable. In this paper, we develop a framework that incorporates time bands so that the behaviour of each component may be specified at a time granularity that is appropriate for the component and its properties. We implement our controllers using teleo-reactive programs, which are high-level programs that are well-suited to controlling reactive systems in dynamic environments. We develop rely/guarantee-style reasoning rules and as an example, prove properties of a well-known mine-pump system.
