Abstract: Abstract. The article examines the application of the PERT method (Program Evaluation and Review Technique) for expert-based duration assessment in analyzing alternative scenarios for eliminating the consequences of emergency structural failures. The study focuses on selecting the optimal organizational and technological solution for restoring damaged critical infrastructure under conditions of time constraints, uncertainty, and limited initial information. The PERT method, based on three-point time estimates (optimistic, most likely, and pessimistic), enables modeling of the time boundaries for each stage of emergency recovery operations. The study proposes and analyzes four scenarios: the use of traditional scaffolding, a scissor lift, a modular assembly platform, and a modular platform integrated with an Information and Mathematical Strengthening Optimization System (IMSOS). For each scenario, expert evaluation was conducted for the duration of nine key stages of the emergency recovery process, considering access to damaged structures, selection of support elements, execution of temporary reinforcement, and organization of deformation monitoring. The results of the comparative analysis demonstrated that the scenario involving the modular platform combined with IMSOS is the most effective in terms of minimizing the total project duration. The proposed approach allows engineers and project teams to quickly adapt organizational and technological decisions to emergency conditions, reduce the risk of delays, and ensure timely restoration of structural functionality.
