The phrase "availability function" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or operations research, where it refers to a function that describes the availability of resources or systems over time.
Example: "The availability function of the server indicates its operational status throughout the day, helping us identify peak usage times."
Alternatives: "availability model" or "resource availability function".
An alternative formulation of the availability function in terms of internal energy is proposed.
The strict convexity of the availability function is guaranteed as long as one of the extensive variables is fixed.
On the other hand, a classical result on the use of the second law of thermodynamics for the stabilization of irreversible processes is the celebrated thermodynamic availability function.
The DTVGM-ET improved the ETa computation on the basis of a nonlinear soil water availability function to establish an explicit time response relationship between ETa and soil moisture for implementing the ETa assimilation.
For this general reaction scheme, the control problem is shown to be easy to solve as soon as the closed loop Hamiltonian function is chosen to be proportional to the so-called thermodynamic availability function.
It is shown that the availability function can be split into two parts: one corresponds to the mixing term and depends on mole numbers only and the other depends on both temperature and mole numbers.
In all, the TSPA compiled data on over 3200 indicators of service functionality from a 283 page questionnaire addressing themes about staffing patterns and availability, functioning equipment, essential drugs, and other elements of service readiness, assessed in a single episode of data compilation.
The objectives of this paper is to propose the concept of a theoretical performance limit for the plants and propose a method for the determination of this performance limit using computer simulations with idealized energy availability functions.
In this paper, we propose the use of discrete-event simulation (DES) as an efficient methodology to obtain estimates of both survival and availability functions in time-dependent real systems—such as telecommunication networks or distributed computer systems.
Taking these into consideration helped developing appropriate availability functions for the redundant system.
The above three equations may be interpreted as characteristics availability functions which convert commodities into attributes.
