Figure14a shows that high node density helps RECRA to preserve pre-failure coverage because of availability of intermediate non-critical nodes and overlapped coverage among nodes.
Of the remaining two-thirds of availability failures, more than 70% are caused by intentional management decisions or by management inaction.
Daily checks should be made on manual cranking of the pump for use in the event of a power failure, on the availability of a pump head for emergency replacement of a malfunctioning pump, and on clamps.
Robustness complements reliability and availability: reliability quantifies the frequency of failures and availability reflects the fraction of the time when the system is up and running (implying repair).
Results have shown that system1 was the best in terms of availability, meantime to system failure and cost benefit ratio.
The output risk indicators of device level separately are failure rate and availability of a device, risks of load isolation & power-supply isolation, and the margin of interface transmission.
Participating Sierra Leonean clinicians identified five main categories of failure modes (resource availability, environmental issues, staff knowledge and attitudes, and workload and staffing issues) and four categories of mitigation strategies (resource management plans, engaging and educating stakeholders, peer support for new machine use, and collectively advocating for needed resources).
Ongoing growth in the number of patients with kidney failure and limited availability of kidney transplants leads to long waiting lists and poor quality of life.
The effects of various combinations of reliability, failure rate, and availability onto the system MTBF are studied through sensitivity analysis.
Commenting on one of the key factors, the report concluded: "Obesity is caused not by moral failure of individuals but by the excess availability of high-fat, high-sugar foods".
