European-derived law with electrical and electrotechnical control system safety requirements

This work reviews the innovative and progressive methods of determination and analysis of safety objectives using Vilnius A-SMGCS example. The aim of the analysis is to determine how failures in this system could affect flight safety in Vilnius aerodrome. Identified safety objectives will limit the frequency of occurrence of hazards enough for the associated risk to be acceptable, and will ensure that appropriate mitigation means are reflected subsequently as Safety Requirements for the system. Analysis reflects aspects of A-SMGCS Safety objectives, which should be taken into consideration. Santrauka Darbe apžvelgiami progresyvūs saugos tikslų analizės metodai pagal Vilniaus aerodromo automatizuotos antžeminio eismo stebėjimo ir kontrolės sistemos veiklos pavyzdį. Analizuojama, kaip šios sistemos sutrikimai gali paveikti skrydžių saugą Vilniaus aerodrome. Remiantis galimų pavojų skrydžių saugai analize, tyrime nustatyti saugos tikslai, pagal kuriuos vėliau bus numatomos riziką mažinančios priemonės (galimų pavojų neutralizavimui ar kylančios rizikos sumažinimui iki priimtino lygio). Straipsnyje pateikiami veiksniai, kuriuos reikėtų įvertinti nustatant aerodromo automatizuotos antžeminio eismo stebėjimo ir kontrolės sistemos saugos tikslus.

Architectural Evaluation

This chapter introduces an analysis process that combines the different perspectives of system decomposition with hazard analysis methods to identify the safety-related use cases and scenarios. It argues that the derived safety-related use cases and scenarios, which are the detailed instantiations of system safety requirements, serve as input to future software architectural evaluation. Furthermore, by modeling the derived safety-related use cases and scenarios into UML (Unified Modeling Language) diagrams, the authors hope that visualization of system safety requirements will not only help to enrich the knowledge of system behaviors but also provide a reusable asset to support system development and evolution.

Mechanism Control

A special-purpose robot for prostatectomies has been developed. Details of the robot mechanism, control system and human/computer interface (HCI) are discussed with special emphasis on software methods to ensure system safety. The clinical application of the system is described and software requirements for operating-theatre use are indicated. These requirements include safe error recovery, facilitation of reliable surgical procedures, and an effective HCI.
