Methodological approaches to increase the fault tolerance of software system in multiversion environments

Abstract

The article considers the approach to develop of adaptive n-variant software based on versioning. The technological process is presented as a model of functionality. This article proposes approach based on the segmentation of versions functionality. Note that approach is aimed at increasing the unit algorithmic fullness of the version. It is shown that spatially-distributed architecture of model is formed using the proposed approach. The article presents approach to form logical functional levels that is focused on prioritization of functional tasks taking into account the system operational needs.

Analysis of the influence of natural and climatic conditions in the Arctic and the Far North on the stability of air traffic

“…The development and applicability of the theory of reliability of satellite data transmission systems were studied by such Russian and foreign scientists as Slepchenko A.P., Skrypnik O.N., Tolstikov A.S., Vychuzhanin V.B., Kalach G.G., Tkachev E. A., Dobrikov V.A., Bakholdin V.S., Sakhno I.V., Fateev V.F., Andreev A.G., Koverznev E.A., Badvan A.A., Nguen M.T., Joau A.F., Tei Z.U., Amro M.M., Le S.H., Din C.Z. [9][10][11].…”

Methods for identification of objects of development of cross‐ platform on‐board software for communication and navigation satellites

“…The architectural basis of the cross-platform OBS of navigation communication satellites (Figure 2) is presented in [10][11][12]. The most important functional characteristics of the designed software components, as can be seen from the diagram presented in [13,14], are: used queues, ports, supported hardware and low-level inter-hardware communication protocols.…”
