Research on land-based pre-dispatch of marine oil spill emergency materials based on blockchain technology

Rapid and effective pre-dispatch of emergency materials for oil spill accidents is of great significance to ensure the supply of materials in port reserves and to improve the emergency response capability of marine oil spill accidents. In order to deal with the situation that the supply of materials in the port area reserves is insufficient in the event of a major marine oil spill accident, and materials need to be transferred from the onshore reserves, a land-based pre-dispatching system for emergency materials based on blockchain technology is studied, and the overall architecture and functional model of the system are proposed. At the same time, for the decision-making module of emergency materials dispatch scheme in the pre-dispatching system, an emergency materials dispatch model is constructed, and the entropy weight-TOPSIS method and genetic algorithm are used to solve the model, and the effectiveness of the dispatch model is proved by case analysis. The research results can optimize the inventory and dispatch management of emergency materials in the land transportation stage, realize the automatic matching between the supply and demand sides and the rapid formulation of the land deployment plan, and provide a reference for the pre-dispatch decision of emergency materials.
