Problems solved by technology

The traditional hybrid leapfrog algorithm solves the heuristic information of emergency material scheduling without using the problem, and cannot guarantee that the fitness value can be improved after the individual is updated, resulting in the waste of part of the computing resources on blind search. Converge to global optimum

Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0070] The present invention is an emergency material scheduling method based on rescue urgency. Material scheduling is used for fixed-point delivery of materials in disaster areas. Disasters can be natural disasters, famine, floods, etc., and floods can be delivered by small boats.

[0071] Take earthquake disaster as an example:

[0072] In a test example with a disaster area size of 51, 9 aid vehicles need to serve 50 disaster areas, the demand for the disaster ...

Abstract

The invention discloses an emergency material dispatching method based on rescue emergency degree, and relates to the technical field of material dispatching. The method comprises the following steps: determining a boundary between a lagging supply area and a non-lagging supply area of an assistance vehicle, obtaining a punishment value of the lagging supply area of the assistance vehicle, obtaining a target value according to the punishment value and a path length, and obtaining the fitness of each individual; dividing subgroups according to the fitness, and using a multi-individual greedy cross strategy to update the individual with the worst fitness of the subgroups; performing internal path updating on the individuals with the worst sub-group fitness by adopting a worst individual part information cross strategy; remixing the data in the updated subgroups; and updating an iteration counter, outputting an individual with the optimal fitness, and determining a supply sequence of the disaster area which should be rescued. When a disaster occurs, subsequent calculation resource waste on blind search is reduced, so that the algorithm convergence speed is improved.

Description

technical field [0001] The invention belongs to the technical field of material dispatching, in particular to an emergency material dispatching method based on rescue urgency. Background technique [0002] In recent years, frequent earthquakes have caused heavy casualties and property losses. In order to reduce the damage caused by natural disasters to the people and the country and enable the country to develop stably, it is necessary to establish a complete emergency response system. Different from general commercial logistics, due to the weak economy of relief materials, emergency material dispatching is more concerned with meeting the material needs of various disaster areas on the basis of rapid supply of materials, so as to reduce casualties. Post-disaster emergency material dispatch (EMS) is an important part of the emergency management system. Timely and reasonable distribution of materials to each disaster area can reduce the damage caused by the disaster and provi...
