Embodiment Construction

[0074] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0075] Such as figure 1 The shown emergency resource allocation method based on multi-objective fuzzy programming for marine oil spill accidents has uncertainties in the voyage time of rescue ships and the resource demand of each oil spill point due to the changeable natural conditions at sea and the disaster situation cannot be accurately estimated. Using the most typical triangular fuzzy numbers to deal with this kind of uncertainty problem, the specific steps are as follows:

[0076] Step 1: The number of known emergency resource distribution centers is n, and each emergency resource distribution center (at least two) is recorded as A 1 ,A 2 ,...,A i ,...,A n , 1≤i≤n, when the marine ship oil spill accident occurs, use the satellite geographic information system (GIS, Geographic Information System) to determine the number m of oil spill p...

Abstract

The invention discloses a marine ship oil spill accident emergency resource allocation method based on multi-objective fuzzy programming. The method includes the steps that 1, uncertain sailing duration and resource demand quantity are represented as the triangle fuzzy number, determination representation is conducted on fuzzy emergency starting time through the complete integral of a time membership degree function, demand quantity membership degree is used to represent the demand satisfaction degree of the resource amount received by oil spill points, and thus the timeliness and the demand satisfaction degree objective function of the emergency system are set; 2, the maximum of the total sailing safety index of rescue ships serves as the safety objective, and the minimum of the sum of the rescue ships serves as economy sub objectives; 3, nondimensionalization is conducted on all the sub objectives, and a multi-objective planning model is built with the timeliness of the system, the demand satisfaction degree, safety and economy as the optimal objective through a liner weighting method. By means of the marine ship oil spill accident emergency resource allocation method based on multi-objective fuzzy programming, the nondeterminacy of the sailing duration of the rescue ships and the resource demand quantity of the oil spill points can be processed effectively.

Description

technical field [0001] The invention relates to the technical field of emergency resource allocation for ship oil spill accidents, in particular to a method for allocating emergency resources for marine ship oil spill accidents based on multi-objective fuzzy programming. Background technique [0002] As my country's oil imports have increased year by year in recent years, marine oil spill accidents have become more and more frequent. In the emergency rescue process of ship oil spill accidents, it is very important to allocate emergency resources reasonably and efficiently to control the spread of pollution and reduce economic losses. However, the maritime emergency environment has the characteristics of unpredictable disasters, harsh natural conditions, and unpredictable sea and meteorological conditions. In addition, fires or explosions caused by oil spills bring huge risks to the safety of navigation and rescue processes of emergency ships. . Therefore, compared with oth...
