An extended robust mathematical model to project the course of COVID-19 epidemic in Iran

Reza Lotfi et al.

Summary: This research develops a regression-based Robust Optimization approach to predict the number of COVID-19 patients and estimate the necessary resources. The suggested model is compared to other forecasting models and validated through sensitivity analyses. The results show that increasing the degree of regression and reducing regression uncertainty can improve the accuracy of the model.

Hybrid Fuzzy and Data-Driven Robust Optimization for Resilience and Sustainable Health Care Supply Chain with Vendor-Managed Inventory Approach

Reza Lotfi et al.

Summary: One of the best strategies for managing and reducing inventory costs in COVID-19 conditions is Vendor-Managed Inventory (VMI) policy. This study proposes a hybrid fuzzy and data-driven robust optimization approach for Resilience and Sustainable Health Care Supply Chain (RSHCSC) with VMI to improve inventory management and tackle uncertainty and disruption. Three RSHCSC models are suggested using different optimization techniques, and sensitivity analysis is conducted on key parameters.

A novel COVID-19 epidemiological model with explicit susceptible and asymptomatic isolation compartments reveals unexpected consequences of timing social distancing

Jana L. Gevertz et al.

Summary: This study introduces a new epidemiological model to analyze the impact of different rate control strategies on the spread of COVID-19. It also explores the critical implementation delay in issuing social distancing mandates and the importance of timely action to meet healthcare resource capacity. The study reveals that reopening society too quickly may offset the progress made under initial social distancing guidelines, but careful design of relaxation strategies can help mitigate negative effects.

A new fractional mathematical modelling of COVID-19 with the availability of vaccine

Pushpendra Kumar et al.

Summary: This study introduces a new SEIRS dynamic model incorporating vaccine rate and utilizes Atangana-Baleanu fractional derivative to explore the disease model dynamics. Real data from Spain is used for parameter values, and Predictor-Corrector algorithm is employed to derive model solutions. The main aim is to demonstrate the significant role of vaccines during the critical period of COVID-19.

State estimation-based control of COVID-19 epidemic before and after vaccine development

Arman Rajaei et al.

Summary: In this study, a nonlinear robust control policy is designed to manage the outbreak of COVID-19 with uncertain epidemiological model. Two scenarios are proposed for controlling the epidemic before and after vaccine development, using social distancing, hospitalization rates, and vaccination rates as control inputs. The feedback control measures are defined based on hospitalized and deceased populations, while unmeasurable variables are estimated using an extended Kalman filter. The stability and bounded tracking convergence of the closed-loop epidemiological system are investigated in the presence of modeling uncertainties, and comprehensive simulation study based on Canada's reported cases shows the effectiveness of the developed control scheme.

Mathematical modeling of the COVID-19 pandemic with intervention strategies

Subhas Khajanchi et al.

Summary: Mathematical modeling is crucial for understanding disease dynamics and designing strategies to manage infectious diseases like COVID-19 without a vaccine. By calibrating a SEIR model with daily data from provinces in India, conducting sensitivity analysis and making short-term and long-term predictions, the study shows that reducing the transmission coefficient and outbreak rate is critical to control outbreaks.
