In this study, we developed a Caputo-Fractional Chlamydia pandemic model to describe the disease's spread. We demonstrated the model's positivity and boundedness, ensuring biological relevance. The existence and uniqueness of the model's solution were established, and we investigated the stability of the α-fractional order model. Our analysis proved that the disease-free equilibrium point is locally asymptotically stable. Additionally, we showed that the model has a single endemic equilibrium point, which is globally asymptotically stable when [Formula: see text] exceeds 1. Using Latin Hypercube sampling and partial rank correlation coefficients (PRCCs), sensitivity analysis identified key parameters influencing [Formula: see text]. Numerical simulations further illustrated the impact of parameter variations on disease dynamics.
在本研究中,我们开发了一个Caputo分数阶衣原体大流行模型来描述该疾病的传播。我们证明了模型的正性和有界性,确保了生物学相关性。建立了模型解的存在性和唯一性,并研究了α分数阶模型的稳定性。我们的分析证明无病平衡点是局部渐近稳定的。此外,我们表明该模型有一个单一的地方病平衡点,当[公式:见原文]超过1时,它是全局渐近稳定的。使用拉丁超立方抽样和偏秩相关系数(PRCCs),敏感性分析确定了影响[公式:见原文]的关键参数。数值模拟进一步说明了参数变化对疾病动态的影响。
