Operational availability is used to evaluate the following performance characteristic. For a system that is expected to be available constantly, the below operational availability figures translate to the system being unavailable for approximately the following lengths of time (when all outages during a year are added together):
Availability, operational (Ao) [7] The probability that an item will operate satisfactorily at a given point in time when used in an actual or realistic operating and support environment. It includes logistics time, ready time, and waiting or administrative downtime, and both preventive and corrective maintenance downtime.
Availability includes non-operational periods associated with reliability, maintenance, and logistics. This is measured in terms of nines. Five-9's (99.999%) means less than 5 minutes when the system is not operating correctly over the span of one year. Availability is only meaningful for supportable systems.
The availability factor of a power plant is the duration it achieves production of electricity divided by the duration that it was planned to produce electricity. In the field of reliability engineering , availability factor is known as operational availability , A o {\displaystyle A_{o}} .
Additional funds needed (AFN) is a financial concept used when a business looks to expand its operations. Since a business that seeks to increase its sales level will require more assets to meet that goal, some provision must be made to accommodate the change in assets.
In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability; Availability: Ability to keep a functioning state in the given environment
[1] [2] Studies show that the availability of funds within a company is a major driver for investment decisions. [3] However, the success and growth of a company is almost entirely dependant on the financial management and the use of internal financing does not explicitly mean success or growth for the firm.
The Net Stable Funding Ratio seeks to calculate the proportion of Available Stable Funding ("ASF"), via equity and certain liabilities, over Required Stable Funding ("RSF") via the assets. Sources of Available Stable Funding includes: customer deposits, long-term wholesale funding (from the interbank lending market), and equity.
