Ship Damage Control as a Service Based on Spatio-temporal Database

To solve the increasingly prominent contradiction between the traditional damage control and the demand of high efficiency and reliability of ship system, a ship damage control system based on spatio-temporal database is presented and accomplished with cloud solution. A path planning algorithm based on Dijkstra is proposed to meet the dynamic road network as in the fire rescue scenario. The binary group is adopted to describe the weight of the path, and path network is pruning to reduce nodes accessed in advance. The simulation results show that the proposed algorithm improves the efficiency, capacity, intelligence and user experience, and provide efficient support for assistant decision-making.
