Abstract
In this paper, we introduce realvalued temporal logic (RVTL) for online monitoring of reactive and cyberphysical systems. Our approach is based on classical metric temporal logic (MTL) with a realvalued semantics, where the truth value of a formula with respect to a finite trace depends on the distance between the end of the trace and the bound of the temporal operators in the formula. The assumed time model is dense and pointwise, i.e., the basic propositions refer to events reported by the system at specific times. We show that our logic is applicable for collaborating cyberphysical systems by giving example formulae from a case study of autonomous transport robots in a factory. We sketch an algorithm for monitoring RVTL formulae at runtime, and report on experiences with this algorithm in an actual industrial deployment of the case study.
