TL;DR: It is concluded that it will not be sufficient to improve design processes, raise the level of abstraction, or verify designs that are built on today's abstractions to realize the full potential of cyber-Physical Systems.
Abstract: Cyber-Physical Systems (CPS) are integrations of computation and physical processes. Embedded computers and networks monitor and control the physical processes, usually with feedback loops where physical processes affect computations and vice versa. The economic and societal potential of such systems is vastly greater than what has been realized, and major investments are being made worldwide to develop the technology. There are considerable challenges, particularly because the physical components of such systems introduce safety and reliability requirements qualitatively different from those in general- purpose computing. Moreover, physical components are qualitatively different from object-oriented software components. Standard abstractions based on method calls and threads do not work. This paper examines the challenges in designing such systems, and in particular raises the question of whether today's computing and networking technologies provide an adequate foundation for CPS. It concludes that it will not be sufficient to improve design processes, raise the level of abstraction, or verify (formally or otherwise) designs that are built on today's abstractions. To realize the full potential of CPS, we will have to rebuild computing and networking abstractions. These abstractions will have to embrace physical dynamics and computation in a unified way.

TL;DR: An overview of the Time-Triggered Architecture is given, the architectural principles are discussed, the sensor/actuator interfaces in the TTA are described, the implementation of fault-tolerance is informed and the provision of fully specified interfaces between subsystems is described.
Abstract: The Time-Triggered Architecture (TTA) is a computer architecture for distributed real-time systems in safety critical applications, such as computer controlled brakes, or computer assisted steering in an automobile. The TTA is a composable architecture for the design of large real-time systems. Its main characteristics are a common notion of time in all subsystems of the architecture and the provision of fully specified interfaces, called temporal firewalls, between these subsystems. This paper gives an overview of the TTA, discusses the architectural principles, describes the sensor/actuator interfaces in the TTA and informs about the implementation of fault-tolerance in the TTA.

TL;DR: The rational for and an outline of the design of a time-triggered (TT) Ethernet that unifies real-time and non-real-time traffic into a single coherent communication architecture are presented.
Abstract: This paper presents the rational for and an outline of the design of a time-triggered (TT) Ethernet that unifies real-time and non-real-time traffic into a single coherent communication architecture. TT Ethernet is intended to support all types of applications, from simple data acquisition systems, to multimedia systems up to the most demanding safety-critical real-time control systems which require a fault-tolerant communication service that must be certified. TT Ethernet distinguishes between two traffic categories: the standard event-triggered Ethernet traffic and the time-triggered traffic that is temporally guaranteed. The event triggered traffic in TT Ethernet is handled in conformance with the existing Ethernet standards of the IEEE. The design of TT Ethernet has been driven by the requirement of certification of safety-critical configurations and an uncompromising stand with respect to the integration of legacy applications and legacy Ethernet hardware.

TL;DR: An overview of the new extensibility mechanisms of UML 2.1 is provided and a method for defining profiles that greatly increases the likelihood of producing technically correct quality UML profiles is described.
Abstract: UML includes special extensibility mechanisms, which are used to define domain-specific modeling languages that are based on UML. These mechanisms have been significantly improved in the latest versions of UML. Unfortunately, there is currently a dearth of published material on how to best exploit these capabilities and, consequently, many UML profiles are either invalid or of poor quality. In this paper, we first provide an overview of the new extensibility mechanisms of UML 2.1 and then describe a method for defining profiles that greatly increases the likelihood of producing technically correct quality UML profiles

TL;DR: Major challenges for organic system design arise from the conflicting requirements to have systems that are at the same time robust and adaptive, having sufficient degrees of freedom for showing self-x properties but being open for human intervention and operating with respect to appropriate rules and constraints to prevent the occurrence of undesired emergent behavior.
Abstract: Organic computing is becoming the new vision for the design of complex systems, satisfying human needs for trustworthy systems that behave life-like by adapting autonomously to dynamic changes of the environment, and have self-x properties as postulated for autonomic computing. Organic computing is a response to the threatening view of being surrounded by interacting and self-organizing systems which may become unmanageable, showing undesired emergent behavior. Major challenges for organic system design arise from the conflicting requirements to have systems that are at the same time robust and adaptive, having sufficient degrees of freedom for showing self-x properties but being open for human intervention and operating with respect to appropriate rules and constraints to prevent the occurrence of undesired emergent behavior.
