Hierarchical Reliability and Safety Models of Fault Tolerant Distributed Industrial Control Systemse studied. Two fault tolerant architectures for the distributed system nodes are explained and their influence in the whole system is evaluated. Also the benefits of using checkpointing techniques are presented. In order to do the hierarchical models we use stochastic activity networks and the UltraSAN tool.

From Public Service to Professionalism,rements documents and the critical function list are the key documents in this process. Bottom-up analysis (FMECA) and test, on both subsystem and system level, are the basis for safety verification. A number of examples show the use of the approach and methods used.

Global Inequality and the Rise of the South,, which is closer to human cognition than that obtained from a conventional approach. Potential improvements achieved by this SML-based method include efficient checking of information completeness, tracing of review issues, and reduction of clerical work in license review.

Safety Analysis Techniques for Validating Formal Models during Verificationin this paper integrates traditional deductive and inductive analysis techniques with model checking, a form of formal verification. The aim is to provide the safety analyst with a rigorous approach for the validation of formal models.

Impact of Communication on Systems Dependability: Human Factors Perspectivesobal system dependability which rests on mechanisms such as error detection, recovery, and prevention (by anticipation and regulation). This study helps providing specifications for the design of systems efficiently supporting both human cooperation, and human ability to contribute to dependability.

Hierarchically Performed Hazard Origin and Propagation Studiestrees, and can guarantee the consistency of results. HiP-HOPS is currently supported by a tool called the Safety Argument Manager (SAM). In this paper we introduce the method and we show how it has helped us analyse and improve the safety of a distributed brake-by-wire system for cars.
