    Development of micro-commands according to logical schemes of algorithmic technical documentation in railway automation

    In this research, a formal strategy for enhancing the electronic distribution of technical documents in railway automation and telemechanics is developed. The accounting and control of device-related documents are formalized using a graph-based model. By creating maximally compatible (non-contradictory) groupings of LSA elements, a micro-command system is created using logical scheme algorithm (LSA) A71 as a case study, illustrating how to simplify the logical scheme (LS). In order to characterize the methods for producing the subsequent micro-instruction code and to depict the parallel execution of internal and external micro-operations, matrix representations are introduced. The study thus suggests a useful formal model and graphical approaches for the analysis, synthesis, and assessment of workflows involving electronic technical documents. These methods aim to minimize the number of internal states in logical structures by forming compatible groups of LSA elements. The resulting micro-commands allow the simultaneous execution of multiple micro-operations within a single micro-cycle, thereby increasing processing efficiency. Extended logical schemes were introduced to better assess the complexity of automata used in managing electronic technical documents. A graphical model of the logical schemes is developed, offering practical tools to design and optimize automation processes. The proposed approach simplifies the control structure while maintaining the system’s functionality, allowing for more efficient monitoring and real-time control in railway operations. This methodology is especially relevant for modernizing technical documentation systems used in the transport sector and integrating them with automation and control mechanisms.
