“…It should be noted that there is no universal model of the software evaluation and test planning. Moreover, beside the described classes of models, studies suggest simulation models [29], structural models [22], fuzzy models [26,27], interval models [30], software dynamic models [31][32][33], software/hardware complex models [34,35], Bayesian model modifications [19,30,36,37], as well as neural networks applied for certain scientific purposes [38,39]. In order to select a suitable model, a number of qualitative and quantitative criteria can be suggested [40].…”
