Serious accidents in the last years, e.g. Concorde disaster, long-distance train ICE 3rd generation, and countless and increasing rates of call-back actions of automobiles because of failures, underline the necessity for systematic dependability analysis and integrative dependability design. The different technological areas (mechanics, electronics, information and communication technology) and...

This paper presents a Generalizability Theory (GT) analysis of the dependability of measures obtained using the Seevers, Dormody and VanLeeuwen (1998) SET instrument. The analysis of Seevers , et al. (1998) data suggests that both student means and class means are sufficiently reliable measuresfor most purposes. These data are used to illustrate the GT estimation of reliabilities for both stude...

This paper describes a model that defines the attributes of domestic systems that lead to system dependability and a user-oriented specification method for support systems based on this model. We start by discussing technical dependability models and discuss how these have to be extended for use in a domestic context. We present an extended dependability model based on a socio-technical perspec...

This report describes several different approaches to Command and Control System vulnerability analysis. The focus is on practical heuristics that can be used without a significant loss of accuracy. Topics covered are qualitative criticality evaluation of C2 nodes, identification of degradation sources, and dependability evaluation of digital C2 support systems. The use of the possibility measu...

Integrated silicon photonics represents one of the more promising solutions to overcome the challenge of worsening on-chip communication performance in emerging multicore platforms. This paper highlights recent innovations in architectures, protocols, and techniques to enhance performance, dependability, and power-efficiency for integrated photonics. Keywords—integrated silicon photonics, photo...

Dependability is a composite property consisting of attributes such as reliability, availability, safety and security. The achievement of these attributes is often essential for the operational success of systems undertaking critical and complex tasks. Assurance that the final system will demonstrate the required dependability qualities, can be crucial to the acceptance of the system into servi...

Discrete-state Markov processes are very common models used for performance and dependability evaluation of, for example, distributed information and communication systems. Over the last fifteen years, compositional model construction and model checking algorithms have been studied for these processes, and variations thereof, especially processes incorporating nondeterministic choices. In this ...
