What must happen to assure that some aspects of separation services can safely be performed in the cockpit? The ASAS concept proposes the transfer of responsibility for maintaining aircraft separation from the ground to the airborne side under specific conditions. With the emergence of an operational requirement for ASAS applications, their safety issues need to be addressed as soon as possible...

Food preferably has to be tasteful, healthy, attractive, and affordable, but should above all be safe. The safety of our daily food nowadays is at a reasonable level, but is far from obvious. With a certain frequency, food safety incidents come up, and the increasing complexity and globalization of our food production networks contribute to an easy outgrow of such incidents to international cri...

We study the risk assessment of uncertain cash flows in terms of dynamic convex risk measures for processes as introduced in Cheridito, Delbaen, and Kupper [10]. These risk measures take into account not only the amounts but also the timing of a cash flow. We discuss their robust representation in terms of suitably penalized probability measures on the optional σ-field. This yields an explicit ...

To overcome the difficulty in understanding quantitative evaluation on actually safety assessment, This research proposed a qualitative comprehensive assessment method of fuzzy state based on fuzzy Analytic Hierarchy Process (AHP) and Fuzzy Transform. First of all, the fuzzy comment of multiple assessments by experts should focus on the quantitative evaluation of corresponding triangular fuzzy ...

In 2005, our hospital participated in a Canadian Council on Health Services Accreditation (CCHSA) Patient Safety Cultural Assessment project. Online survey results collected and analyzed by CCHSA demonstrated numerous opportunities for our organization to improve its patient safety culture. An eight-point Patient Safety Plan was created, and over the following two years, numerous patient safety...

The use of mowing robots in anthropic environment is increasing, leading to the call for specific safety standards. This is a challenging endeavour, however, because the user must usually be placed in the robot's workspace and the residents must frequently interact with the robot. Although specific safety standards for mowing robots do not yet exist, there are several mowing device standards an...

After the grounding of the Exxon Valdez and its subsequent oil spill, all parties with interests in Prince William Sound (PWS) were eager to prevent another major pollution event. While they implemented several measures to reduce the risk of an oil spill, the stakeholders disagreed about the effectiveness of these measures and the potential effectiveness of further proposed measures. They forme...

 The implementation of autonomous vehicles involves an increase in the number and depth of system interactions in comparison to user-driven cars. There is a corresponding need to address the system safety implications of autonomy. Traditional hazard analysis techniques are not designed to identify hazardous states caused by system interactions. An emerging technique based on systems theory, Sy...
