Random emergency material shortage propagation and transverse multistage resupply system design method

Abstract

The invention provides a random emergency material shortage propagation and transverse multistage resupply system design method, and relates to the technical field of system design. The random emergency material shortage propagation and transverse multi-stage resupply system design method comprises the steps that: before system design preparation work, the research progress about virus propagation and diffusion rules and control methods and emergency material transverse supply at home and abroad can be looked up, the research progress is combined with theories and methods used for solving the emergency material transverse supply problem, and a foundation is laid for work content before system design preparation. A transverse supply mechanism is introduced for maintenance spare parts, a multi-target emergency material transverse multi-stage re-supply model is established, actual cases are adopted for verification and analysis, a post-earthquake initial stage emergency material transverse supply scheme is solved and optimized, the emergency rescue timeliness is improved, and meanwhile, the reasonability of the designed emergency material shortage transverse supply model is also proved.

Description

Technical field [0001] The present invention relates to the field of system design technology, specifically a random emergency material shortage propagation and a horizontal multi-stage re-supply system design method. Background technique [0002] In recent years, in response to a series of major emergencies such as SARS, rain and snow, earthquake, mudslide, water pollution, and flu, the development of the reform committee with relevant departments, and undertake the coordination of emergency materials and key production factors. Based on the inherent characteristics of emergency support, such as emergency materials involve the broad, the maintenance needs uncertainty, the work is often cross-regional cross-disaster, and the participating staff is diversified, and the common characteristics of the emergency response phase. Clearly propose practical standards of emergency material classification methods to form a unified understanding of the emergency support key range, constructi...

Problems solved by technology

Efforts should be made to avoid such phenomena as emergency preparedness being untargeted, unspecific and impractical requirements for materials mentioned at the first time, lack of pertinence in resource organization, hectic and disorderly coordination and support, etc.

[0003] When the existing stochastic emergency material shortage propagation and horizontal multi-level resupply system design methods are actually applied, there is a lack of analysis of the impact of emergency material shortage on the basis of existing research on virus transmission models, considering the characteristics of the model and combining it with material shortages to derive it. The propagation characteristics in the network, combined with the material shortage network and emergency rescue network, lack the rationality of the designed emergency material shortage horizontal supply model
