Criteria are established in this standard for variable selection, performance, design, and qualification of accident monitoring instrumentation for anticipated operational, design basisevents and Severe Accidents.Show More
The authors of the article identified socioeconomic and environmental criterions for technological safety of production activities of enterprises in the electrotechnical industry. The stability parameters of electrotechnical companies are formed. A model of technological safety management based on the basis of identified safety criterions and the Zwicky cube has been developed. Based on the morpho...Show More

Included requirements for display alternatives for accident monitoring instrumentation, documentation of design bases, and use of portable instrumentation.Show More
Road safety is a major problem to deal with due to its impact on human lives. Indeed, implementing a straight and a clear road safety strategy leads to a decrease in road accidents and therefore its resulting injuries and fatalities. As a matter of fact, the multi criteria decision aiding methods find naturally their place since we are dealing with a ranking problem within a hierarchical structure...Show More
Ariane 5 rocket which is a test flight of European Space Agency was exploded 37 seconds after launch due to a malfunction in the control software. The amount of this loss is more than US$370 million. The accident has initiated the criticality of the software safety. Nowadays software is widely used in the safety critical system because of the merit of the flexibility. But the flexibility makes it ...Show More
The increase in road accidents underscores the urgent need for effective methodologies to evaluate and prioritize road safety improvements. Traditional decision-making processes in road safety management often confront challenges due to the lack of a comprehensive approach, particularly in handling multiple evaluation criteria. This study introduces a novel Hybrid Multi-Criteria Decision-Making ap...Show More
Software is widely used in the railway system such as train propulsion system, brake system, train control system, train detection system and driver display unit. Unfortunately, there is no software criteria and development procedure that are required to get the qualified software. Although analysis and evaluation of each step in the software lifecycle are the basic activity, direct coding to get ...Show More
Key Performance Indicators play a crucial role in monitoring and evaluating the performance of road safety systems. However, the process of selecting the most representative indicators can be challenging due to the multi-dimensional nature of road safety and the large number of available indicators. In this study, we propose a comprehensive approach for the effective ranking and prioritization of ...Show More

The digital system performs more varying and highly complex functions efficiently compared to the existing analog system because software can be flexibly designed and implemented. The flexible design makes it difficult to predict the software failures. Even though the main characteristic of railway system is to ensure safety, nowadays software is widely used in the safety critical railway system j...Show More
The influence of construction safety on a project is complex and important, including schedule on milestones, delays in project duration and cost overruns. So a number of safety improvement measures have been taken to migrate this problem in the construction industry of China in the face of the poor safety records. However, not all of these programs are effective enough to satisfy with the need of...Show More
Regulatory requirements and industrial codes and standards (C&S) are to be compulsory top-tier prerequisites for the design and construction of the fusion DEMO plant of Korea (DEMO Plant) as it will have safety-related functions to mitigate radiation hazards to the environment. However, these prerequisites will be developed in parallel with the design and construction of DEMO Plant due to the firs...Show More
The paper considers the criteria for the safety and quality of air in artificial human habitats, the factors of the influence of atmospheric air on the human environment, the main factors of influence of atmospheric air on the human environment. Risk factors of air security violation from internal sources of air pollution discussed.Show More
The application of the single-failure criterion to the electrical power, instrumentaion, and control portions of nuclear power generating station safety systems is covered. Conformance with the requirements of IEEE Std 603-1991 and the single-failure criterion as stated in that document is established. Interpretation and guidance in the application of the single-failure criterion, a discussion of ...Show More
Software safety criteria plays a very important role in verifying software safety, and it offers the target when we carry out safety analysis. However, the software criteria has not been widely applied, because the description in natural language may be semantically vague and the manual verification brings huge workload. Formal methods can just make up the above weakness because of its rigorous lo...Show More
This paper deals with research of safety performance predictions to allow improved risk control in military. Safety performance is identified as appropriate tool to establish system-wide information on safety which can serve the decision making process on how to manage safety. The information contributes to better understanding of behavioural patterns in the controlled system and the ability to fo...Show More
In this paper, the performance of safety management in building construction in China is summarily analyzed. Considered the factors of the underlying causes of the construction safety accidents including staff, equipment, material, technique and circumstance, and combined with the latest study achievement of construction safety management at home and abroad, the underlying causes of poor safety ma...Show More
Software for safety-critical systems must deal with the hazards identified by safety analysis in order to make the system safe, risk-free and fail-safe. Software safety is a composite of many factors. Existing software quality models like McCall's and Boehm's and ISO 9126 are inadequate in addressing the software safety issues of real time safety-critical embedded systems. At present there does no...Show More
Standardization related to electromagnetic compatibility (EMC) is dealt with in a broad range of documents whereas most of them are given in the IEC 61000-X-Y series which includes International Standards, Technical Specifications or Technical Reports. This series is further accompanied by a lot of product family or product specific standards that contain corresponding EMC requirements. Since seve...Show More

This paper deals with safety performance predictions in the aviation, which address the long-term global efforts to achieve predictive risk management by the year 2028. Predictive risk management regards timely and accurate detection of risk, well before some incident or accident takes place so that effective control actions can be provided. To assure achieving such diagnosis, it is necessary that...Show More
With the increasing public awareness of the complexity of road safety phenomenon, much more detailed aspects of crash and injury causation rather than only crash data (e.g., the number of road fatalities) are extensively investigated in the current road safety research. Safety performance indicators (SPIs), which are causally related to the number of crashes or to the injury consequences of a cras...Show More
