A Comprehensive Model for Railway Automation and Remote Control Systems Design Processes

The article presents a model describing the design stage of a railway automation and remote control system for the subsequent construction of a simulation model for analysis, forecasting results, and improving the efficiency of project implementation. Within the context of the model description, the purpose of modelling is defined, the functional requirements are formulated, and the boundaries and assumptions are described. A system analysis of the design stage was performed, and the design stage was broken down into key processes and design steps. The objectives and key performance indicators for design activities were identified, as well as the main issues related to the project duration and the quality of technical documentation presented. A diagram was constructed to illustrate the factors affecting the design time, using the cause-and-effect analysis method as a basis. The development of a classifier of errors in technical documentation within the model frame involved the assignment of weighting coefficients to characterize their degree of criticality and impact on the project quality. A set of input parameters was defined to reflect the scope of the project, determining the volume and content of a specific project. Following a thorough analysis of the data, a structural diagram of the simulation model has been developed. The system is composed of six functional modules, each with a detailed description of their respective tasks, logic of operation, and structure of the processed data. The proposed model can provide a theoretical and methodological foundation for the construction phase of a modulating algorithm and the subsequent software implementation of a simulation model. In addition, it can support the design stage of railway automation and remote control systems.
