OBJECTIVE Administering medication to hospitalised infants and children is a complex process at high risk of error. Failure mode and effect analysis (FMEA) is a proactive tool used to analyse risks, identify failures before they happen and prioritise remedial measures. To examine the hazards associated with the process of drug delivery to children, we performed a proactive risk-assessment analy...

How can evidence from economic evaluations of the type the Disease Control Priorities project have synthesized be translated to better priority setting? This evidence provides insights into how investing in health, particularly though priority interventions and expanded access to health insurance and prepaid care, can not only save lives but also help alleviate poverty and provide financial ris...

The present study aims at investigating the role of risk in the activity of independent technological venturing. Altogether 12 deep-interviews were conducted with technological entrepreneurs, who had taken part in the inventive, developmental and the commercialisation phases of a technologybased innovation process. The interviews revealed a number of enactment approaches through which these inn...

Making critical sections abortable is a promising approach to reducing priority inversions. To improve the schedulability of a system using abortable critical sections, the maximum number of abortions should be decreased. In this paper, we propose a real-time synchronization protocol named the ceiling abort protocol (CAP) which introduces a new priority-based abort scheme to the priority ceilin...

In this paper, we model a call center as a preemptive-resume priority queue with time-varying arrival rates and two priority classes of customers. The low priority customers have a dynamic priority where they become high priority if their waiting-time in queue exceeds a given service-level time. The performance of the call center is measured by the mean number in system for the two customer cla...

Signalling, a complex system is one of the most important infrastructures of railway service. The performance of railway signalling system depends on the functioning of a number of subsystems, such as panel, cable, relay, point and point machine, trackcircuit, signal, back indication, point-drive card, signal-drive card, and level crossing gate. Railway signalling system plays an important role...

This paper presents a nuclear case study, in which a fuzzy inference system (FIS) is used as alternative approach in risk analysis. The main objective of this study is to obtain an understanding of the aging process of an important nuclear power system and how it affects the overall plant safety. This approach uses the concept of a pure fuzzy logic system where the fuzzy rule base consists of a...
