On the application of a model for assessing the transactional reliability of information systems of industrial enterprises

Abstract

Abstract The article examines an example of the application of a model for assessing the transactional reliability of information systems of industrial enterprises. This transactional reliability determines the correctness of the calculations performed and the integrity of the data, and, consequently, the characteristics of the quality of software tools that are used in information systems of industrial enterprises to perform control and data processing functions. It is shown that all the parameters of this model can be obtained from the results of testing the system, which makes it possible to construct adequate estimates of the reliability parameters. The calculated indicators obtained using the developed model differed from the real ones by no more than 5%, which indicates the sufficient adequacy of the model. The modern system Microsoft Dynamics 365 for Finance and Operations (Dynamics AX/Axapta) was used as an environment for modeling and analyzing the transactional reliability of software tools.
