Because COVID-19 is an extremely hot topic and the most fascinating question in recent years, the research on this topic is very interesting and noticed by scientists. Design/methodology/approach: In the scope of this study, we first introduce definitions and issues related to COVID-19 and study the negative impacts of COVID-19 diseases on all sectors of society. We then provide a comprehensive introduction to the applied aspects of Decision Science in the prevention of COVID-19. Findings: The findings of our research help people have a correct, complete, overview,and comprehensive view of the COVID-19 issue. All COVID-19 issues are discussed in great detail and completeness in this article. Originality/value: All the issues discussed in this study are original and new in the literary literature. Practical implications: This will help the countries'leaders have the best way to fight the COVID-19 pandemic more effectively and cost-effectively. © 2022 Hindawi Limited.

Given the negative effects of COVID-19, this study aims to estimate accurate forecasts of the number of confirmed cases to help policymakers determine and make the right decisions. Design/methodology/approach: This paper uses a hybrid approach for forecasting the daily COVID-19 cases based on combining the Autoregressive Integrated Moving Average (ARIMA) and Autoregressive Neural Network (NNAR) with a single hidden layer. To fit the linear pattern from the data, ARIMA models are used. Then, the NNAR models are used to capture the nonlinear pattern. The final prediction is obtained by adding up the two predictions. Findings: Using six-time series from January 22, 2020, to June 22, 2021, of new daily confirmed cases of COVID-19 from Pakistan, Tunisia, Indonesia, Malaysia, India and South Korea, this work evaluates the hybrid approach against some benchmark models and generated ten days ahead forecasts. Experiments demonstrate the superiority of the hybrid model over the benchmark models. Originality/value: Given the complex nature of new confirmed cases, it is assumed that the data contains both linear and nonlinear components. In literature, different studies have tended to forecast future cases of COVID-19. However, most of them have used single models that capture either linear or nonlinear patterns. This paper proposes a hybrid model that captures both linear and nonlinear components from the data.","PeriodicalId":38875,"journal":{"name":"Advances in Decision Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70852461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Predictive analysis has been gaining much attention in the late 20th century and it has been around for decades, but as technology advances, so does this technique and the techniques include data mining, big data analytics, and prescriptive analytics.
