“…With the deepening of research, more and more scholars began to study the timeliness of emergency materials distribution. Wang et al [14] and Ren et al [15] developed a location-allocation model with the objectives of minimizing emergency response time and maximizing satisfaction, Wang et al [16] developed an emergency logistics network optimization model with the objectives of minimizing logistics operating costs and minimizing total distribution time, taking into account factors such as emergency response speed. Long et al [17] developed a multi-stage siting-distribution model for emergency materials.…”

During the epidemic outbreak period, the number of infected people increased explosively. In order to effectively contain the further spread of the epidemic and treat infected people, it is necessary to make reasonable planning for the treatment of infected people and the distribution of materials. In this paper, a multi-objective mixed-integer programming model for the integrated design of emergency medical and material distribution networks is developed, in which the location of medical points, the allocation of infected people, and the distribution of medical materials are addressed in the multi-stage planning. Then, the multi-objective model is solved by the augmented ε-constraint method. A realistic case study on Huangpu District of Shanghai in China is conducted to demonstrate the validity of the developed model. The results show that the integrated consideration of the emergency medical network and the material distribution network is more capable of reducing the total transportation distance and decreasing the total operating cost.

Lacking timely access to rescue resources is one of the main causes of casualties in tunnel collapse. To provide timely rescue, this study proposed a multi-objective preallocation model of special emergency resources for tunnel collapse based on demand time. Efficiency, multiple coverage, and cost-effectiveness are taken as the key objectives of the model; the demand time service range is used as a coverage decision factor considering the unique nature of tunnel collapse. The weight of potential disaster-affected points and other general factors are also considered in this model in order to thoroughly combine the distribution of disaster points and service areas. Further, we take 15 main tunnel projects under construction in China as an example. When the relative proximity to the ideal point of the selected optimal scheme εa is smaller than 0.5, we will adjust the weight of three objectives and reselect the optimal scheme until εa > 0.5. Compared with the not preallocated case, the number of rescue rigs needed is reduced by 8.3%, the number of covered potential disaster-affected points is increased by 36.36%, the weighted coverage times are increased from 0.853 to 1.383, and the weighted distance is significantly reduced by 99% when the rescue rigs are preallocated, verifying the feasibility and superiority of the proposed model.
