From the past earthquake events, m at the exit while they are trying to go out of the bu the exit doors are unable to be opened. The door is it deviates from its the original position. The aim o develop and evaluate a new type safety door that ke in its original position or keeps its edge angles pe and post-earthquake. The proposed door is c components: outer frame joined to the wall, inner and...

Software is taking over more and more functionality in most technical systems, which leads to the term software-intensive or cyber-physical systems. Although this offers many exciting new opportunities, it also makes precise analysis of safety and reliability goals much more complicated. Well-known traditional techniques often reach their limits. Model-based approaches on the other hand can be ...

ion of state descriptions. It must be possible to abstract the results of an envisionment so that they can be compared with the descriptions of interesting states. This area is in its infancy, but we would expect it to make a significant contribution to system safety and reliability as it becomes better developed.

This paper describes a framework for assessing the system safety impacts of an Adaptive or Intelligent Cruise Control (ICC) system. This framework incorporates a time-to-collision model that is developed from vehicle headway, speed, and acceleration data that are typically gathered as part of field operational tests. Specifically, the framework combines car-following models with vehicle deceler...

Increased reliance upon outsourcing has made the issue of vendor selection even more critical to the success of the modern manufacturing organization. The usual performance measure on which selection is based has been the distribution of the vendor’s delivery lead-time (LT), often as characterized by the mean and variance. In this paper, we show that the distribution of demand per unit time (DP...

We consider the possibility of prior discovery of slip-type human error by quantifying the “distraction” state that precedes it. We investigated brain activity during the task of keyboard-based text input taking incorrect input as a slip-type error. We used sensitivity spectrum analysis to quantify four output states. We attempted to detect in correct input by discriminating between the output ...

Humans may be viewed as being merely fallible operators of machines; however, that technology-centred view can easily understate the ability of the human to perform tasks which most machines are incapable of doing and to intervene in the event of failure. On the other hand, an overly human-centred view may not take full advantage of the ability of machines to carry out numerically-complex, repe...

NASA has recently instituted requirements for establishing Agency-level safety thresholds and goals that define long-term targeted and maximum tolerable levels of risk to the crew as guidance to developers in evaluating “how safe is safe enough” for a given type of mission. This paper discusses some key concepts regarding the role of the Agency’s safety thresholds and goals in achieving adequat...

By-wire systems have been established for several years in the area of aircraft construction and there are now approaches to utilize this technology in vehicles. The required electronic systems must evidently be available and safe. In the same time the requirements of mass production have to be reached (long life time, long maintainability intervals, low costs, fulfillment of standards). This p...
