Embodiment Construction

[0054] In this implementation example, a modular scheduling method for emergency supplies based on the improved NSGA-II algorithm, the process is as follows figure 1 As shown, the principle and method of simultaneous arrival in the modular dispatching of relief materials are studied according to the characteristics of the storage method, type and quantity of relief materials, that is, a single type of material is stored in the reserve warehouse before the disaster, and it is transported to the nearby disaster area after the disaster occurs. The distribution center of relief materials carries out modular packaging and then transports them to the material demand points in the disaster area. Then, an improved NSGA-II algorithm is used to solve the problem, so as to obtain a rescue material scheduling plan, which can greatly reduce the total cost of rescue work and improve rescue efficiency. Specifically, it is applied to a rescue material type set D={y 1 ,y 2 ,...,y s ,...,y ...

Abstract

The invention discloses an improved NSGA-II algorithm-based modular scheduling method of emergency response materials. The method includes: 1, generating an initial population and genetic variables thereof according to constraint conditions; 2, carrying out crossover and heredity on the population to generate a child population; 3, merging the parent population and the child population, and carrying out fast non-dominated sorting on a merged population; 4, calculating a chromosome neighborhood set, and adopting an elimination mechanisms to select a new parent population; 5, repeating the step2, the step 3 and the step 4 until maximum iteration frequency is reached; and 6, selecting all non-dominated solutions of a population to use the same as optimal scheduling schemes. According to themethod, the optimal schemes of modular scheduling of the rescue materials can be obtained, thus rescue costs can be reduced, rescue efficiency can be improved, and timely effective developing of rescue work can be guaranteed.

Description

technical field [0001] The invention belongs to the field of emergency logistics, and in particular relates to a modular scheduling method for emergency materials based on the improved NSGA-II algorithm. Background technique [0002] Emergency material scheduling is the core link of emergency management. It mainly studies how to quickly and effectively use intelligent decision-making theory and computer-aided tools after a disaster occurs to select a set of optimal emergency resource allocation plans and distribution routes, so that scattered materials can arrive as soon as possible. Each disaster-affected point, thus greatly reducing the casualties and economic losses caused by sudden disasters. Therefore, the government and emergency management departments must formulate effective emergency material dispatching measures to ensure that the emergency material supply is in place in time and avoid secondary disasters caused by untimely material supply. [0003] In terms of em...
