Safety and reliability issues

With current technology, it is possible in principle to develop computer based instrumentation and control systems with the necessary dependabihty for systems important to safety and to demonstrate their safety sufficiently. However,

The high-temperature crude corrosivity of distillation units is a major problem in the refining industry. The presence of naphthenic acid and sulfur compounds increases corrosion in the high-temperature parts of the distillation units and hence equipment failure became a critical safety and reliability issue. Most of the acids have the formula R(CH2) C00H, where R stands for the cyclopentane ring and n is greater than 12. In addition to R(CH2) COOH, a host of other acidic organic compounds are also present. 

Finally, market competition has encouraged the management of commercial nuclear power stations to become more efficient and less bureaucratic. This change is especially great in the U.K., which had recently evolved from governmental ownership and direction under the CEGB. As a result, it is possible that resources required to address safety and reliability issues can now be allocated more quickly than under the previous ownership regime. 

On the one hand, privatization and restructuring have brought about safety improvements and efficiencies in operations. For example, there appears to be a significantly heightened interest in the reliability of those systems and components that can affect power output or threaten regulatory action. The new commercial ownership of some U.K. nuclear power stations has also reduced the former degree of bureaucracy. As a result, it is possible that resources for safety and reliability issues can now be allocated more quickly. 

Excellent safety and reliability issues. Low heat generation during operation. Recoverable even after short-circuiting.

Modem trends in the field of material flows projection aim at a purposeful systematic approach. The quality, safety, and reliability issues are crucial input parameters at the projection stage of a material flow system. 

The objectives for quality control should relate to the standards you wish to maintain or to prevent from deteriorating. At the corporate level these objectives will address strategic issues such as safety and reliability or customer care. Although you will be striving...

Collect and evaluate real-world data to address safety and environmental issues, develop statistically validated codes and standards, formulate policies and regulations, and understand reliability and large-scale deployment of hydrogen technology under diverse operating conditions. 

Safety and reliability of chemical process plants are such important issues, they deserve the best techniques to prevent problems occurring. To minimize risks resulted from operating problems and hazardous events, process system safety and reliability analysis is often employed. This is a rigorous approach undertaken to improve system reliability and safety. The approach consists of three main tasks hazard identification, risk estimation, and risk control. 

Telehealthcare Issues of safety and reliability remain very important in telehealthcare. The demands of developing equipment at an appropriate level of sophistication may be especially great, for telehealthcare often requires quantitative measurement by the patient in a home environment. One of the potential benefits of telehealthcare is that it can increase the agency of patients, as they become more active in the treatment of their condition. However, such benefit may be diminished if they feel unable to cope adequately with their monitoring equipment. 

Generic Safety Issue (GSI) II.c.4 in NUREG-0933 (Reference 1), addresses the need for a designer and owner-operator developed reliability program which can evaluate plant safety and reliability. 

Unlike United States experience with nuclear power prior to the 1979 Three Mile Island accident, the future exploration of nuclear energy will not be dominated by issues based solely on technical grounds. Nuclear power is a proven technology, but safety and reliability concerns of fhe public musf be addressed as parf of the public acceptance strategy. The public perception of nuclear power risks is fhe legacy of the Three Mile Island accident. Concessions and efforts not necessarily directly linked to safety issues may be necessary and should be part of the framework and mindsef of any such program. 

After hazard identification, design constraints are placed and seen from the perspective of human operation, software, etc. especially for programmable electronics (PE). However, this may not completely get rid of hazards, so they are also traced at a software level. For any product safety and reliability are important issue and their intimate relationship has been explained in Fig. 111/1.9.1-1. This is standard practice in product development. 

Measure All these attributes need to be suitably measured to get an idea of the dependability of the system. Major issues like availability, safety, and reliability were discussed earlier and hence are not repeated here. Apart from these there shall be a few other measurable issues such as performability, testability (self-explanatory), and maintainability. 

Although not required by regulation for OS HA PSM and EPA RMP covered facilities, some companies are finding that PSSR for some routine maintenance activities can provide a return on investment. Certainly process safety and personnel safety benefit, but general quality and reliability issues are also avoided with a good PSSR program.

ABSTRACT Economical risks are directly connected with the technological risks. One major problem of a integrated technical and economic risk assessment is the identification of a suitable method, which can combine technological, safety and economical issues in one risk assessment. The Monte-Carlo-Simulation is used in both sciences (engineering economics) and can be adapted to perform a combine risk assessment. The paper explains the Monte-Carlo-Simulation integrated in a V-model process. Via a V-model the different issues can be partitioned, analysed on a low level (component reliability, safety and price) and later combined to a complete system risk assessment. 

Not only technical safety and security issues can influence the risk potential of a product. Also the economical risks depending on the reliability of a product are very important for the manufacturer or the maintenance service company. New contract types are dominating the maintenance market. One example is the automotive industry which highly increasing warranty periods which new risk potential has to be transferred to the suppliers. Also flatrate maintenance contracts for end-users... 

Speaking of issue of safety and reliability of the system, we should pay attention to a very broad aspect of this issue. We can consider production systems, distribution systems, civil infrastructure (such as transportation, water supply, sewers, telecommunications, and electrical and gasnetworks) and the other. In the literature many articles can be found refering to a safety and reliability of various systems (Braglia et al., 2012), (Kim Kang,...
