Integration of methodological solutions for the assessment of the stability of large technical systems operation

To improve the management processes of large technical systems, aspects of methodological solutions integration for the development and integrated application of a model for ensuring sustainability and methods for assessing the sustainable functioning of those systems are considered. The model is designed to simulate the dynamics of stability states of a large technical system by calculating losses, as in the case of the time and resources spent on restoring the system in adverse conditions. In the model, for systematization and the most rational use of the simulation results in computer programs, unified tabular forms have been developed, suitable for modeling the stability states of various systems. The simulation results are proposed to be used in the methodology for assessing the stability of the functioning of large technical systems. The methodology calculates a complex indicator: the functioning of a large technical system. The formula for calculating the stability coefficient is obtained based on the criterion of the effectiveness of a complex system while conserving resources and timely restoration of system elements. A computer program implements this technique and uses unified tabular forms from the model for ensuring system stability. The complex application of the model and methodology is aimed at making timely rational management decisions to ensure the stable functioning of large technical systems in the conditions of unstable dynamics of semi-structured data on the state of the system, the availability of resources, and the results of the external environment. In the future, the presented model and methodology can be used to develop methods for registering complex events (within visibility on the event horizon) and identifying scenarios for their development to improve the efficiency of proactive management of large technical systems.
