Safety-critical systems are systems where failures lead to catastrophic results: resulting in loss of life, significant property damage, or damage to the environment. These systems range from aerospace on-board control systems, ground flight control systems, medical devices, nuclear power plants control, automotive systems, military systems, just to name a few. Other information systems are becoming...
The paper is devoted to the safety of complex technical systems of systems (SoS) through the improvement of engineering processes at all system lifecycle stages. The safety of complex technical facilities (such as nuclear and conventional power plants, offshore oil and gas platforms and chemical processing plants) is analyzed based on the systems theory and SoS engineering. The safety concept discussed...
Medication management process in a hospital includes all the work that is done concerning to a certain patient's medical treatment. According to international studies, the process is very prone to errors, which can cause adverse drug events and endanger the patient safety. In this paper, we will show how medication management process can be improved by a user-centric and computer-based automated dose-dispensing...
Based on various factors which influence on aviation maintenance safety, the multi-index system of aviation maintenance safety was constructed and the quantitive rule of the index was ascertained, the synthetical sequencing model of aviation maintenance multi-index safety was established in the employ of principal component analysis method. An example of the safety of 3 units of aviation maintenance...
Defects in information technology (IT) services will have greater negative impacts on social and economic activities in the future, since the risks of such defects are increasing due to their wider applications and the growth of IT systems' complexity and scale. In this paper, upon surveying the current state of affairs and seeing that little progress has been made towards understanding and reducing...
Human-Machine-Interfaces are with no doubt one of the constitutive parts of an automation system. However, it is not till recently that they have received appropriate attention in order to improve the design of SCADA applications in industrial domain. It is because of a major concern about aspects related to maintenance, safety, achieve operator awareness, etc has been gained. Even there are in the...
Accident model,i.e. accident-causing theory, that is a main component of Principium of Safety, is an important part of accident theory. It avoids concrete characteristic of hazard source and content and mode of accident temporarily. Instead, abstractly thinking of person, machine, goods and environment in system, revealed accident causes, processes and results in nature.After many researches, it appears...
This paper aimed to develop a quantitative and objective method to analyze and evaluate human factors in aviation maintenance process. Firstly a detailed classification and causing analysis on human errors in aviation maintenance was carried out basing on SHEL and Reason Model; then an integrated evaluation solution was proposed out by using fuzzy and AHP method together. Then the solution was applied...
Although the need for humans and robots to work together in close proximity is increasing, this is currently not allowed with conventional industrial robots for reasons of safety. Next generation robots that can work safely in close proximity with humans must not only be highly functional, but must also be highly reliable with built in safety features. With this aim in mind, we have developed a safety...
The Product Assurance and Safety Department of the European Space Agency ESA is part of the Directorate of Technical and Quality Management. The Quality Dependability and Product Assurance Support Division and the Independent Safety Office deal with safety and dependability. Among the recent safety and dependability study initiatives is the development of a catalogue of failure event input data and...
In this paper, a safety management information system (SMIS) is constructed to change the situation of inefficiency of safety work for traditional safe management in China. Firstly, according to several relative theories such as system safety management theory and management information system theory, four subsystems and five function modules are designed for the internal system of SMIS to store,...
