Annotation: Modern information systems (IS) are complex systems and their design requires significant financial and time costs and is associated with significant risks. In this regard, the development of a methodology for assessing the readiness of IS projects is a very urgent task. This article analyzes approaches to assessing the level of readiness of scientific and technical IS projects based on the use of a 9-level scale. Proposals for their improvement for application in Russia, including the development of new standards, are formulated.

Annotation: The features of planning, development and application of standards to ensure interoperability in modern conditions are considered. It is noted that ensuring interoperability is currently one of the key directions of standardization. A look at modern conditions is given. The approach to ensuring interoperability proposed by the V.A. Kotelnikov IRE of the Russian Academy of Sciences, which is entrusted with the management of the PC206/TC22 "Interoperability" subcommittee, developed standards and difficulties encountered in the implementation of this approach, is described. In conclusion, suggestions are given for the formation of a solution to the of interoperability problem.

Annotation: The current state of ensuring e-health interoperability is considered and a conceptual approach to ensuring interoperability based on GOST R 55062-2021 is proposed, taking into account the provisions of GOST R 59797-2021. The innovation consists in considering the ecosystem of digital healthcare in Russia as a complex system and as an integral part of the Unified Information Space of the Russian Federation, arising as a result of the processes of digital transformation of the economy. A practical tool from the described approach of ensuring interoperability should be a profile that takes into account both the requirements of processes in electronic health care and the applied advanced information technologies, for example, cloud computing. With the achievement of interoperability in the field of e-health, it is expected to improve the quality of services provided to the population.

Annotation: In the modern world, the processing and analysis of large volumes of data are becoming increasingly important for the successful functioning of information systems. However, effective data classification can be difficult due to various costs, such as time, computational, and those specific to a particular domain. This article considers approaches to data classification taking into account these costs in information systems. An overview of existing methods for cost-sensitive classification is presented, as well as the application of a data classification algorithm that takes into account costs in various industries. An island genetic algorithm is used to optimize the parameters and select the weights of the classifier model.

Annotation: The article provides a brief overview of modern PLM systems, which are software for managing the life cycle of a product, and CRM systems focused on interaction with enterprise customers. The capabilities and features of systems of this class are analyzed, an approach to including these systems in a single information space of enterprise information systems is considered to improve the efficiency of business processes using the example of existing companies, and ways to solve issues of increasing the competitiveness of a business using the integration of the systems under consideration are proposed.

Annotation: Various planning and resource allocation problems can be reduced to the graph coloring problem. In particular, graph coloring is used in high-level synthesis of digital circuits. The exact solution for graph coloring is not always practically achievable. For this reason, heuristic graph coloring algorithms, which allow to obtain a feasible solution with polynomial computational complexity, are of interest. Such algorithms can be used, in particular, in the problem of fast design space exploration in high-level synthesis of digital system. In this regard, the Ershov-Kozhukhin family of heuristic algorithms, which has been so far unmentioned in the modern literature on analysis of graph coloring algorithms, is of interest. A brief description and pseudocode of the Ershov-Kozhukhin algorithms is given and their experimental evaluation in comparison to the Welsh-Powell, RLF and DSATUR algorithms is presented in the paper. The evaluation shows that the Ershov-Kozhukhin algorithms have an advantage in the quality of the generated solutions compared to popular heuristic graph coloring algorithms.

Annotation: Digital financial assets are widely used because of their ease of use, greater accessibility to investors and reduced costs for issuers. Nevertheless, like traditional financial instruments, digital financial assets are subject to technical and infrastructural risks. It is possible to reduce the consequences in case these risks materialize by implementing digital financial assets distributed between several information systems, which, in turn, will require ensuring synchronization between platforms. The aim of the work is to develop an architectural approach to ensure synchronization of distributed digital financial assets.
