“…Among our own previous work, our paper [7] introduces the formal effort/flow-based object-oriented modeling technique for continuously interacting hybrid systems; the papers [42,22] describe how the Euler and the Runge-Kutta numerical approximation methods have been adapted to the effort/flow setting and then formalized/implemented in Maude. The papers [4,5] introduce the HI-Maude tool, and, finally, the paper [18] provides a shorter exposition of the sauna case study. The precise relationship between [18] and the current paper is given in the introduction.…”

“…HI-Maude [4,5] is a language and analysis tool that extends Maude [20] and its real-time extension Real-Time Maude [21] to support the object-oriented effort/flow-based modeling and approximation-based formal analysis of interacting hybrid systems. Since HI-Maude targets complex systems, and therefore does not restrict to linear ODEs for describing the continuous dynamics of a component/interaction, the continuous dynamics of a system is in general not analytically solvable.…”

“…In this paper we use the rewriting-logic-based HI-Maude language and tool [4,5] to model the human thermoregulatory system according to established medical/physiological models and to analyze it under extreme conditions. Since our investigation is partially motivated by the 2010 Sauna World Championships, we also present a fairly detailed model of the thermodynamics of a sauna and use the HI-Maude tool to address the three questions above.…”

“…Fadlisyah et al have defined a way of decomposing the definition of the complex continuous behaviors in hybrid systems where the continuous behavior of a component may depend on the continuous behaviors of other components [16]. The associated HI-Maude tool [15] provides a number of numerical approximation methods for such systems, including the Euler and Runge-Kutta methods [5], and has been used to model and analyze the human thermoregulatory system [17].…”

Distributed cyber-physical systems (DCPS), such as aeronautics and ground transportation systems, are very hard to design and verify, because of asynchronous communication, network delays, and clock skews. Their model checking verification typically becomes unfeasible due to the huge state space explosion caused by the system's concurrency. The Multirate PALS ("physically asynchronous, logically synchronous") methodology has been proposed to reduce the design and verification of a DCPS to the much simpler task of designing and verifying its underlying synchronous version, where components may operate with different periods. This paper presents a methodology for formally modeling and verifying multirate DCPSs using Multirate PALS. In particular, this methodology explains how to deal with the system's physical environment in Multirate PALS. We illustrate our methodology with a multirate DCPS consisting of an airplane maneuvered by a pilot, who turns the airplane to a specified angle through a distributed control system. Our formal analysis using Real-Time Maude revealed that the original design did not achieve a smooth turning maneuver, and led to a redesign of the system. We then use model checking and Multirate PALS to prove that the redesigned system satisfies the desired correctness properties, whereas model checking the corresponding asynchronous model is unfeasible. This shows that Multirate PALS is not only effective for formal DCPS verification, but can also be used effectively in the DCPS design process.

Real-Time Maude extends the rewriting-logic-based Maude system to support the executable formal modeling and analysis of realtime systems. Real-Time Maude is characterized by its general and expressive, yet intuitive, specification formalism, and offers a spectrum of formal analysis methods, including: rewriting for simulation purposes, search for reachability analysis, and both untimed and metric temporal logic model checking. Real-Time Maude is particularly suitable for specifying real-time systems in an object-oriented style, and its flexible formalism makes it easy to model different forms of communication. This modeling flexibility, and the usefulness of both Real-Time Maude simulation and model checking, has been demonstrated in many advanced state-of-the-art applications, including both distributed protocols of different kinds and industrial embedded systems. Furthermore, Real-Time Maude's expressiveness has also been exploited to define the formal semantics of a number of modeling languages for real-time/embedded systems. Real-Time Maude thereby provides formal analysis for these languages for free, and such analysis has been integrated into the tool environment of a number of modeling languages. This paper gives an informal overview of Real-Time Maude and some of its applications.
