  Safety and Reliability of Complex Engineered Systems contains the Proceedings of the 25th European Safety and Reliability Conference, ESREL 2015, held 7-10 September 2015 in Zurich, Switzerland. It includes about 570 papers accepted for presentation at the conference. These contributions focus on theories and methods in the area of risk, safety and reliability, and their applications to a wide range of industrial, civil and social sectors. The main goal of this book is to showcase the advancements in understanding, modeling and management of complex engineered systems. The book offers a multidisciplinary platform to address technological, societal and financial aspects of system safety and reliability. Emphasis is given to the intra- and interdependencies of functions and the cascading failures that characterize complex engineered systems. Safety and Reliability of Complex Engineered Systems (abstracts book 730 pages + full paper CD-ROM 4634 pages) will be of interest to academics and professionals involved or interested in aspect of risk, safety and reliability in various engineering areas.

  In this paper, we present the Safe Control Systems (SaCS) pattern language for the development of conceptual safety designs and conduct an analytical evaluation of the appropriateness of the language for its intended task. By a conceptual safety design we mean an early stage specification of system requirements, system design, and safety case for a safety critical system. The SaCS pattern language can express basic patterns on different aspects of relevance for conceptual safety designs. SaCS can also be used to combine basic patterns into composite patterns. A composite pattern can be instantiated into a conceptual safety design. A framework for evaluating modelling languages is used to conduct the evaluation. The quality of a language is within the framework expressed by six appropriateness factors. A set of requirements is associated with each appropriateness factor. The extent to which these requirements are fulfilled are used to judge the quality.We discuss the fulfilment of the requirements formulated for the language on the basis of the theoretical, technical, and practical considerations

  The Safe Control Systems (SaCS) method is a pattern-based method supporting the development of conceptual designs for safety critical systems. A pattern language offers support for the method by six different kinds of basic patterns, operators for combining patterns, and a graphical notation for visualising a pattern composition. Intended users of SaCS are system developers, safety engineers and HW/SW engineers. The method has so far been applied in two cases within different industrial domains. This paper demonstrates and presents experiences from the application of SaCS within the railway domain. We consider an interlocking system that controls the appliances of a railway station. We argue that SaCS effectively supports the establishment of requirements, a design satisfying the requirements, and an outline of a safety demonstration for the design.

  This article exemplifies the application of a pattern-based method, called SaCS (Safe Control Systems), on a case taken from the nuclear domain. The method is supported by a pattern language and provides guidance on the development of design concepts for safety critical systems. The SaCS language offers six different kinds of basic patterns as well as operators for composition.

  This article puts forward a pattern language for Safe Adaptive Control Software named SACS. We interpret the term “pattern language” such that a set of patterns, the interconnections between them, and how these are intended to be used make up a language. The pattern language consists of three basic types of patterns, namely the Requirement Pattern , the Design Pattern, and the Safety Case Pattern and an additional Composite Pattern type. The Composite Pattern type facilitates users of the language to specify their own patterns as compositions of basic patterns. The patterns are intended to be used in the context of safety related and safety critical systems, thus the safety aspect is a principal concern. The pattern language may be used as a tool for e.g. safety engineers and system developers to increase effectiveness during conceptual design and facilitate effective evaluation of alternative adaptive design solutions with respect to utilisation in a safety related application by a systematic approach for combining best practices.
