Abstract:

Mobile cabin hospitals played an important role in the prevention and control of COVID-19 in Wuhan. However, few studies focus on the optimization of capacity allocation of mobile cabin hospitals, especially from the perspective of equity and spatially explicit optimization. To reconstruct the scenario of mobile cabin hospitals in Wuhan, this paper defines the fairness function first by considering comparison psychology so as to describe the lack of equity perception in the pandemic area. Then, it proposes the optimal capacity allocation model of mobile cabin hospitals considering comparative equity. By using the intermediate variable, the number of patients with mild symptoms that can be accepted for treatment, the proposed model can effectively describe the interaction coupling between the allocation and the pandemic dynamics of mobile cabin hospitals. Compared with the scenario without considering equity, the time-space construction process of mobile cabin hospitals after considering equity is closer to the actual process in Wuhan, while the number of beds required is rather less than actually required. Moreover, by considering equity, the cumulative number of infections is less, and the goal of “all those in need can be treated” could be completed earlier while the proportion of budget allocation is stable. Finally, this paper proposes that the starting time of setting mobile cabin hospitals is very important, while emergency budget has an obvious diminishing effect of marginal utility.
