Item Computer architecture(Ukrainian State University of Science and Technologies, Dnipro, 2023) Yehorov, Oleh I.; Dziuba, Volodymyr V.; Ivin, PavloENG: Methodical recommendations are intended for students of the 3rd year of the specialty 123 "Computer engineering" to prepare for practical work in the discipline "Computer architecture".Item Conceptual Resource-Saving Design of Real-Time Socio-Technical Systems(IOP Publishing Ltd, England, 2021) Kosolapov, Anatolii A.; Ivin, PavloEN: The article discusses the methodological resource-saving approach to the System design of socio-technical systems for real-time managing (STS RTM). The definition of STS RTM from the point of view of computer systems architecture is introduced. This approach made it possible to classify the main paradigms of using computer systems, including the modern stage, corresponding to STS RTM. For such complex systems, it is important to ensure their energy efficiency, which is ensured by the use of resource-saving models and methods for optimizing structural solutions. This is ensured by minimizing the total length of communications at the enterprise, saving computing and financial resources during system migration from a centralized structure to a functionally distributed hierarchical multi-microcontroller system. STS is a human a real-time machine system, therefore, the system's response time to the processing of requests related to the issuance of messages to the system's operating personnel is determined. The complex of formulated tasks and their solution on a common information and analytical base is extremely difficult without a unified system design methodology and automation tools for solving problems. Such a Framework is described in this article.Item Information Analytics of Solve a Problem of Software Reliability Evaluation for Sociotechnical Systems at the Conceptual Design Stag(ДВНЗ «ПДТУ», Маріуполь, 2021) Kosolapov, Anatolii A.; Ivin, PavloEN: The scientific works proposes a method for evaluation the software reliability of a computer-based process control in real time system at the at the conceptual design stage. The proposed approach makes it possible to evaluate the possibilities of reserving transactions in real time.Item Real-time Sociotechnical Systems: Early Software Reliability Evaluation(Seventh Sense Research Group®, 2020) Kosolapov, Anatolii A.; Ivin, PavloEN: The article proposes a method for evaluation the software reliability of a computer-based process control in real time system at the early stages of design. Models for the description of automated objects, functioning processes and tasks to be solved are proposed. The concept of a transaction is introduced, a method for evaluation the probability of its smooth operation and availability. For the entire system, the average availability factor is calculated, and the average losses due to program failures during transaction processing. The proposed approach makes it possible to evaluate the possibilities of reserving transactions in real time. The proposed models and method are implemented in the socio-technical real-time systems conceptual design framework CoDeCS.
