Availability measures are classified by either the time interval of interest or the mechanisms for the system downtime. If the time interval of interest is the primary concern, we consider instantaneous, limiting, average, and limiting average availability.
The Simple Dietz method [3] applies a simple rate of interest principle, as opposed to the compounding principle underlying the internal rate of return method, and further assumes that flows occur at the midpoint within the time interval (or equivalently that they are distributed evenly throughout the time interval). However, the Simple Dietz ...
In actuarial mathematics, the accumulation function a(t) is a function of time t expressing the ratio of the value at time t (future value) and the initial investment (present value). [1] [2] It is used in interest theory. Thus a(0) = 1 and the value at time t is given by: = ().
Hence, has been chosen accordingly in order to maintain the boundedness of the solution and the time interval of validity of the approximation is < <. The average theorem assumes existence of a connected and bounded region D ⊂ R n {\displaystyle D\subset \mathbb {R} ^{n}} which affects the time interval L {\displaystyle L} of the result validity.
The times interest earned ratio indicates the extent of which earnings are available to meet interest payments. A lower times interest earned ratio means less earnings are available to meet interest payments and that the business is more vulnerable to increases in interest rates and being unable to meet their existing outstanding loan obligations.
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world , is the second , defined as about 9 billion oscillations of the caesium atom.
In Game theory, the minimum effort game or weakest link game is a game in which each person decides how much effort to put in and is rewarded based on the least amount of effort anyone puts in. [1] It is assumed that the reward per unit of effort is greater than the cost per unit effort, otherwise there would be no reason to put in effort.
The repricing model focuses on the potential changes in the net interest income variable. [6] In effect, if interest rates change, interest income and interest expense will change as the various assets and liabilities are repriced, that is, receive new interest rates. There are two advantages of repricing model. First, it is easily to be ...
