Event-Driven Model and Adaptive Reconfiguration Mechanism of Construction Project Lifecycle under Wartime Uncertainty

This paper proposes an event-driven model of wartime uncertainty and an adaptive reconfiguration mechanism for the lifecycle of construction projects. In contrast to traditional approaches that treat uncertainty as parametric deviations, the proposed framework interprets external impacts as discrete events that may affect both the parameter state and the structural configuration of the project lifecycle. The event model enables a unified description of different types of disruptions, including physical damage, resource loss, logistical interruptions, financial constraints, and regulatory changes. Based on this representation, an adaptive mechanism is developed to update the set of admissible transitions and maintain feasible project trajectories under changing conditions. The decision-making process is formalized through an objective function that allows selecting the most appropriate transition between states after an event occurs. The proposed approach provides a basis for adaptive control of construction project lifecycles and can be applied in decision support systems for project management in unstable environments.
