For the first question, we divided the problem into two aspects. On the one hand, we determined the living security ranking of residents affected by the epidemic situation in each district of Wuhan city; on the other hand, we distributed materials according to the ranking.
Specifically, the first aspect is to determine the impact index of material shortage in the region, and based on the principal component analysis method, the dimension of the index is reduced and the main index is selected. Then the data were normalized,
and the weights of the main indicators were obtained by using the information entropy method, and the life security ranking of the residents affected by the epidemic
situation could be obtained by using the TOPSIS method. On the second hand, according to the ranking, we formulate the standard of material distribution and distribute the materials in different places.
2.3 Analysis of question two
Due to the spread of novel coronavirus pneumonia has a great impact on tourism industry, we choose tourism industry to analyze. On the one hand novel coronavirus pneumonia spread. In this paper, we established a system of susceptible population –
latent population – infected population – cured population. Then, based on the actual data, we modified the SEIR transmission model by considering the viral transmission capacity of patients in incubation period and the effect of tracking and isolation
interventions on the epidemic situation. Taking the epidemic situation in Shanghai as an example, this paper analyzes the impact of prevention, control, isolation and centralized treatment on the development of the epidemic situation. On the other hand, tourist demand changes. During the epidemic period, according to the change of tourist demand with days, and considering various factors, the change model of tourist demand was established. Finally, considering the epidemic diffusion model and the demand dynamic change model of the tourism industry in the market, this paper puts forward planning and suggestions for the resumption of work and production of Shanghai Disneyland tourism company under different epidemic levels.
