SOFTWARE IMPLEMENTATION OF DETERMINISTIC AND STATISTICAL METHODS FOR CALCULATING POWER LOSSES AND ACCOUNTING FOR MULTIPLE MODES OF ELECTRIC NETWORK
Reliability is an important component of software quality. Meanwhile, a specific property of the software is the fact that its reliability increases over time due to the detection and elimination of errors («bugs») contained in it. This process is described by mathematical models of reliability growth. The paper analyzes various reliability growth models in relation to perfect and imperfect debugging. The traditional approach to using such models requires specifying all the functions in an analytical form, which is difficult due to the presence of uncertainty. There is shown the possibility of overcoming the noted obstacles through the application of a mathematical technique based on the theory of interval-valued probabilities and the use of expert judgments. This allows us to make the model more adequate to the real conditions.
