Marine ship oil spill accident multi-material emergency scheduling method

Abstract

The invention discloses a marine ship oil spill accident multi-material emergency scheduling method. The method comprises the following steps: scheduling material type confirmation, scheduling ship type confirmation, oil spill accident demand estimation, oil spill drift diffusion simulation, a triangular fuzzy mathematical theory, theoretical model establishment, algorithm design and actual multi-material scheduling scheme determination. Aiming at the characteristics of continuity and drifting diffusivity of marine ship oil spill accidents, the oil spill emergency material scheduling problem under the characteristics of multiple materials and multiple scheduling ships is researched, a drifting diffusion position is determined through GNOME simulation, a material demand point is determined,and then the material demand in a fuzzy state is determined by utilizing a triangular fuzzy number; and finally, an emergency material scheduling model is built for the marine ship oil spill accident. The application of the model needs to clarify the reserve of the emergency storage, the number of schedulable ships, the distance between the emergency storage and an accident point and other information in advance, and solves the problem of scheduling and distribution of various materials by the emergency material storage.

Description

technical field [0001] The invention belongs to the technical field of emergency dispatching of oil spill accidents, and more specifically relates to a multi-material emergency dispatching method for marine oil spill accidents. Background technique [0002] Ships are the main means of transportation at sea. There may be accidents such as collision, grounding, fire or explosion, etc., which may cause damage to equipment in oil storage tanks and gas engine rooms, and oil spill accidents at sea. According to statistics, from 1973 to 2018, there were more than 3,000 ship oil spill accidents in my country's coastal ports, which had a bad impact on the marine environment and caused huge economic losses. Due to the characteristics of uncertainty, drift and diffusion, marine oil spill accidents are special, and the route of emergency material transport ships is less affected. Compared with the damage to the environment and economic losses caused by marine oil spill accidents, transpo...

Spilled oil not only poses a fire hazard, but also causes serious pollution to marine ecology and damages the marine environment

Timely and reasonable scheduling of oil spill emergency supplies is particularly important to reduce potential safety hazards caused by marine oil spill accidents and reduce damage to marine ecology; integrating existing technologies for dispatching oil spill emergency supplies at home and abroad, most of them are emergency The research on the scheduling of a single material with a clear quantity of material demand, and does not combine the specific number of ships that can be dispatched in the port, so we need to propose a multi-material emergency dispatch method for marine oil spill accidents
