A Study on the Olympic Hosting Proposal Based on Comprehensive Evaluation and the ARIMA Model

Abstract

As a significant event, the Olympic Games have attracted considerable attention since their inception. However, in recent times, enthusiasm for hosting the Olympics among countries worldwide has seen a decline. To propose a reasonable Olympic hosting plan, this article establishes an Olympic hosting capability assessment model. The study selected 11 countries that have hosted either the Summer or Winter Olympics in the past 20 years and investigated seven key aspects of evaluation indicators. Using the EWM-AHP method combined with the TOPSIS method, scores were assigned to these 11 countries. Based on the scores, nations that have previously hosted the Olympics were ranked. The top three countries for both Winter and Summer Olympics were identified, suggesting that the Olympic Games rotate among these nations. To predict the future impact of hosting the Olympics on the host country, this article employs the ARIMA model to forecast the future development of the host nations. The results indicate that hosting the Olympics will lead to a rise in the nation's score, thus validating the reasonability of the hosting proposal.
