Duration calculus: Logical foundations
Michael R. Hansen, Zhou Chaochen · Formal Aspects of Computing · 1997
Abstract The Duration Calculus (abbreviated DC) represents a logical approach for formal design of real-time systems, where real numbers are used to model time and Boolean valued functions over time are used to model states and events of real-time systems. Since its introduction, DC has been applied to many case studies and it has been extended in several directions. The aim of this paper is to provide a thorough presentation of the logic.
