Opis:
One of the most important stage of technical system functional safety analysis is defining the safety-related functions as well as determining a safety integrity level (SIL) for each defined function. A properly carried out hazard identification process is the necessary condition for correct definition of the safety-related functions. Determining the safety integrity level (SIL) is based on risk assessment taking into account risk acceptance criteria. It guarantees accurate results which means that the risk associated with technical system is under good control and the risk level can be reduced to acceptable one. There are several safety integrity level determination methods and techniques described in normative documents and many papers. This article is aimed at presentation of some of them and in addition a new approache are outlined.

Opis:
The functional safety management in life cycle is a complex process starting with identifying hazards and defining safety-related functions (SRFs) with regard to the results of risk assessment oriented at determining the safety integrity level of consecutive functions. Another element of such process is a verification of required SIL for considered architectures of safety-related system that implements given safety function. Due to complexity of the problem, to overcome difficulties in safety-related decision making often under considerable uncertainties, usually without taking into account security aspects, we propose to apply the RIDM methodology oriented on functional safety management of programmable control and protection systems in life cycle taking into some more important risk-related factors identified.

Opis:
In the article the ProSIL software for computer aided functional safety management is presented. The software consists of three modules for the determination of the required SIL level (ProSILen) and verification of the SIL level (ProSILver). In the ProSIL the calibrated knowledge-based risk graph method for determining the required safety integrity level (SIL) of the safety functions identified in hazard analysis is implemented. The SILs are then verified for safety-related control and protection systems implementing relevant functions with regard to random failures and potential systematic failures. The assessment methods are compatible with international standards IEC 61508 and IEC 61511. Some current challenges and methodological issues concerning knowledge-based functional safety management in life cycle are also discussed.

Opis:
A security level of distributed control and protection system may have a significant impact on the results of functional safety analysis. However, the issue of integrating the safety and security aspects is difficult and usually is neglected during the functional safety analysis. This article presents a method of functional safety analysis which takes into consideration a concept of integrating these two aspects. It is based on proposed classification of communication channels used in the computer system / network and the scope of such system distribution. The functional safety analysis is to be performed at every stage of system lifecycle, but one of the most important parts is defining required safety functions and determining the safety integrity level for them. The integration concept might be taken into account at this stage. The basis of a method proposed is the assumption that the security level is considered as a risk parameter in graphs of functional safety analyses.

Opis:
In this article a prototype ProSIL software system for computer-aided functional safety management is discribed. The software consists of three modules for: determination of the required SIL level (ProSILen), veryfication of the SIL level (ProSILver), and layer of protection analysis (ProSIL/LOPA). In ProSIL the methods concerning functional safety analysis in the process of the design and operation of Safety Instrumented Systems (SIS) are implemented according to PN-EN 61508 and PN-EN 61511 standards, and some new methods, e.g. the calibrated risk graph method for determining required safety integrity level (SIL) based on the risk assessment. Moreover, methods of veryfying the SIL level of SIS. The Layer of Protection Analysis (LOPA) method with regard to Human Reliability Analysis (HRA) are also included in the software.
