Аннотация
Infrastructure systems face increasing challenges related to cost overruns, operational uncertainty, and riskexposure throughout their lifecycle. Digital twin technology offers new opportunities to support data-driven decisionmakingand improve infrastructure performance. This study aims to develop and evaluate a digital twin-based decisionsupport framework for cost optimization and risk management in infrastructure systems. The methodology integratessystem modeling, real-time data synchronization, and scenario-based simulation within a digital twin environment.Quantitative methods, including lifecycle cost analysis and risk assessment indicators, are applied to compare alternativeinfrastructure management strategies. A case study of infrastructure assets in Eastern Uzbekistan is used to validate theproposed framework. The results indicate that the digital twin-based approach enables a reduction in projected lifecyclecosts by 15-22% and a decrease in risk exposure by up to 18% compared to conventional management methods.Sensitivity analysis confirms the robustness of the framework under varying levels of uncertainty. The practical value ofthis research lies in providing infrastructure managers and policymakers with a scalable decision-support tool to improveinvestment planning, operational efficiency, and risk-informed decision-making
