摘要

This study proposed a method to evaluate the impact of warfare on ship power equipment and quantitatively assess the varying damaged states resulting from multiple strikes. A strike-induced failure grid model is constructed based on the interrelations between the spatially distributed functional components and critical parts of the ship power system. The probability of damage is estimated by analyzing the damage states and the transition probabilities between them. Subsequently, a Markov transition matrix is developed to determine the probability of damage levels under multiple strike scenarios. Furthermore, the contributions of connections in the grid model on the probability of damage level are also analyzed. This approach can contribute to managing warfare-related damage to ship equipment and optimizing the allocation of repair resources. It can also enhance the survivability and operational effectiveness of vessels during missions. A specific steam turbine generator is utilized as a case study.
