Due to the increasing demand for traveling in public transportation systems and increasing traffic of vehicles, nowadays vehicles are getting to be intelligent to increase safety, reduce the probability of accident and also financial costs. Therefore, today, most vehicles are equipped with multiple safety control and vehicle navigation systems. In the process of developing such systems, simulat...

Abstract The reliability and safety of any system is the most important qualitative characteristic of a system. This qualitative characteristic is of particular importance in systems whose functions are under various stresses, such as high temperature, high speed, high pressure, etc. A considerable point, which is rarely taken into account when calculating the reliability and safety of syst...

Background: The reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. Defect and failure in one part of a system can cause total system breakdown or accident. The failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. The purp...

road traffic injuries are known as the most prevalent childhood injury and besides being the greatest cause of child mortality, place an extraordinary burden on health care system. children’s limitation in cognitive, physical and social development makes them more vulnerable in road traffic injuries than adults. their small structure cause challenges to see and be seen and their risk taking beh...

Software changes are difficult since the impacts of the changes are not readily known in advance. For safety-critical system, the changes can even introduce hazards to bug down the system. Then impact analysis makes its way into the software process. It identifies the consequences or ripple-effects of proposed software changes. In impact analysis, identifying the change impacts is a central act...

haemovigilance is a system with standard program to cover the entire transfusion chain, monitor, evaluate and analyse the data to improve patients’ safety. we report the implemented haemovigilance system in hospitals and transfusion reactions (tr) in iran. methods and materials: this was a prospective descriptive study. the national reporting system for transfusion incidents was introduced in j...

We introduce a new method for screening inputs in mathematical or computational models with large numbers of inputs. The method proposed here represents an improvement over the best available practice for this setting when dealing with models having strong interaction effects. When the sample size is sufficiently high the same design can also be used to obtain accurate quantitative estimates of...

Emerging standards and guidelines in the safety engineering field call for the application of safety assessment techniques throughout the development cycle of systems. Since much early work on design projects falls within the discipline of systems engineering, questions arise about the applicability of safety assessment techniques to system architectural descriptions and about the role of such ...
