【摘要】：建立并分析考虑潜伏期及医疗资源影响的SEIS模型,其中医疗资源的影响主要考虑医院病床的数量与恢复率的关系。分析模型发现:当基本再生数R01时,系统只存在唯一正平衡点;当R01时,系统可能存在两个或无正平衡点,并且当医院的病床数小到一定值时,系统会发生后向分支,因此可以找到病床的存在阈值,这样既不造成浪费,又能保证治疗疾病时具有充足的资源。
[Abstract]:The SEIS model considering latent period and medical resources was established and analyzed, in which the effect of medical resources mainly considered the relationship between the number of hospital beds and the recovery rate. It is found that the system only has a unique positive equilibrium point when the number of basic regenerations is R01, and when the number of hospital beds is small to a certain value, the system will have backward branching, while the system may have two or no positive equilibrium points at R01. Therefore, the existence threshold of bed can be found, which can not cause waste and ensure adequate resources for the treatment of diseases.
