Similarly, Team IHME COVID-19 and Murray (2020a) predicted that COVID-19 will place unprecedented stress on hospitals, ICUs, and ventilators, and that the overall demand will be beyond the healthcare system's current capacity. Our results show that the onset and the amount of the excess demand are dependent upon the type of product and the timing of the lockdown. AS Level Topics. Finally, there has been a series of studies focusing on predicting deaths in the USA and European countries for the next few months of the first wave of the COVID-19 pandemic (Team, IHME COVID-19 & Murray, 2020a, 2020b). Shaman and Karspeck (2012) used the Kalman filter based SIR epidemiological model to forecast the peak time of influenza and claimed that the peak can be predicted 67 weeks in advance. (2008) proposed the use of regression methods for the prediction of the peak time and volume (of cases) for a pandemic and provided promising empirical evidence to that end from seven outbreaks (in Sweden). Our analysis covers a major part of the current wave of the pandemic, the period from the 22 January 2020 to 15 April 2020. We performed the clustering with data on socioeconomic, climate, and COVID-19 related factors and grouped them according to whether they are facing, or they are about to face similar challenges.

The linear kernel were used along with eps-regression type from the parameters for the implementation of the method. However, the use of infectious disease forecasts for decision-making is challenging because most existing infectious diseases require different methods for different countries. Furthermore, our results illustrate the challenge of making forecasts and making supply chain decisions for products where consumers need to make judgments about their own immediate needs. Araz O.M., Choi T.-.M., Olson D., Salman F.S. Fig. We further model and forecast the excess demand for products and services during the pandemic using auxiliary data (google trends) and simulating governmental decisions (lockdown). ANN have three layers for data modeling, namely, an input layer, an output layer, and hidden layers. Govindan, Mina and Alavi (2020) presented a decision support system to manage the demand for healthcare supplies based on physicians' knowledge and Fuzzy Inference System (FIS).
