Abstract

The present disclosure provides a hierarchical emergency material allocation method and system based on nonlinear planning, which classifies emergency materials according to their applicable scope, and quantitatively analyzes the daily demand for emergency materials at each disaster-stricken point; the basic principle of putting people first Divide the materials into emergency-level materials and general-level materials, so as to minimize rescue time and reduce casualties in disaster areas; formulate different distribution plans for emergency-level materials and general-level materials; among them, for emergency-level materials, the transportation cost is minimized and the penalty is reduced. The minimum cost and minimum transportation time are used as the objective functions; for general-level materials, the minimum transportation and penalty costs are used as the objective functions, and multi-objective nonlinear programming models are established respectively to optimize the allocation of emergency materials in a fair and reasonable manner and maximize the utility of rescue materials. , to minimize rescue time, thereby reducing post-disaster casualties.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent material distribution, and in particular, to a method and system for hierarchical emergency material distribution based on nonlinear programming. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] Various sudden disasters broke out frequently, which greatly affected people's normal production and life. Large-scale sudden disasters often lead to a large number of casualties and damage to facilities, resulting in a large number of economic losses. After a sudden disaster occurs, the disaster-affected areas will have a large demand for emergency materials in a very short period of time. However, the emergency materials available for use in the early post-disaster period are very limited. Therefore, how to determine the material transportation strategy, scientifica...
