Abstract

When the epidemic comes, in addition to eliminating people’s panic, quickly enacting corresponding laws and implementing corresponding policies, and isolating infected people, providing emergency supplies are of course essential. The purpose of this article is to study the robustness and sustainability of the port logistics system for outbreak emergency supplies from overseas. This paper analyzes the sustainable development capability of the port logistics system for outbreak emergency supplies from overseas and formulates response strategies and robust collaborative optimization methods. The optimized and robust system is obtained through formula derivation and analysis, which realizes the coordinated optimization of emergency logistics infrastructure positioning and emergency rescue vehicle path positioning and minimizes the economic loss caused by the outbreak. Research data show that the shortest path can be planned between each material supply location. The research results show that the proportion of demand fluctuations during the outbreak is 6.5%, the time window needs to be controlled between 0 and 600, and the robustness and sustainability of the port logistics system have saved the time of the entire process by about 45%, greatly optimizing the delivery route and delivery time. The robustness of the logistics system can be widely used in emergency events.

Highlights

In the era of rapid development of science and technology in our country, once the epidemic situation comes, our country must respond within the first time and timely plan the human and material resources for rescue
If the logistics system presents obstacles in any logistics node such as outbound, transportation, and transshipment, a small one will reduce the distribution efficiency and a large one may lead to the paralysis of the entire logistics system. is paper analyzes the sustainable development capabilities of the port logistics system for outbreak emergency materials from overseas and formulates coping strategies and robust collaborative optimization methods. e optimized and robust system is obtained through formula derivation and analysis, which realizes the coordinated optimization of emergency logistics infrastructure positioning and emergency rescue vehicle path positioning and minimizes the economic loss caused by the outbreak
Erefore, this article will use the data in the simulation of real-life training to test whether the optimized port logistics system and sustainability research have ensured the outbreak emergency response from overseas

Summary

Proposed Method

E main task of the logistics node is to be responsible for the management of procurement, warehousing, transportation, distribution, recycling, and other aspects. E emergency logistics system process mainly includes procurement, warehousing, transportation, distribution, recycling, and other links. Each link is important to ensure that emergency supplies can be transported to the designated location in a timely and accurate manner, improve emergency equipment protection, and save costs [12, 13]. The distribution center must collect the types and quantities of the missing materials in detail and respond quickly and accurately to the emergency command department according to the epidemic situation and the lack of emergency supplies [23]. Reusable emergency supplies such as tents need to be cleaned, repaired, and recycled on time.
