Determining interval lengths for fuzzy time series forecasting model based on index of fuzzy sets by combining hedge algebra and particle swarm optimization
Authors: Nghiem Van Tinh  , Bui Thi Thi
Published: December 2023

Researchers frequently use fuzzy time series (FTS) forecasting models to estimate future values since they do not rely on the same rigid assumptions as traditional forecasting techniques. There are generally four factors that determine the performance of the FTS forecasting model (1) determining the length of intervals in the universe of discourse, (2) fuzzification rules or feature representation of crisp time series, (3) establishing fuzzy relation groups (FRGs) and (4) creating defuzzification rule to get crisp forecasted value. Considering the first factor and the fourth factor, we propose the hybrid FTS forecasting model combining particle swarm optimization (PSO) and hedge algebra (HA) to improve forecasting accuracy. Where the hedge algebra is utilized as a tool for partitioning the universe of discourse into intervals of different lengths. Then, the times series data are fuzzified into fuzzy sets, the fuzzy relationship groups are established and forecasting output value based on the index of fuzzy sets is calculated. Ultimately, the suggested model collaborates with PSO to obtain the optimal intervals determined by HA. To test the proposed model, we conduct a simulated study on two widely used real-time series and compare the performance with some recently developed models. Error statistics, such as MSE and RMSE show that the proposed model performs better than the comparing models.

Authors: Eseroghene Udjo , Bejjani Giovanna
Published: December 2023

This study examines tourism recovery patterns in the United Arab Emirates (UAE). The study utilized time series modeling to evaluate the monthly tourism data from the Department of Culture and Tourism (DCT) in Abu Dhabi, covering 2019 to Q1 2023. The LJung box test was used to assess the fit of the dataset with the five tourism parameters: Average Length of Stay (ALOS), Number of Guests (NOG), Revenue Per Available Room (RevPAR), Occupancy Rate (OR), and Tourism Revenue (TR). The presence of nonstationarity was discovered, necessitating the use of data differencing to achieve stationarity.

The results indicate that the model fits the data for the five tourism parameters. The study also reveals a significant decline in UAE tourism visitors, with a modest recovery projected in Q4 2021.The findings demonstrate a substantial decline in hotel occupancy rates (OR) during the COVID-19 pandemic, with a slower recovery rate expected for 2023-2024. The average length of stay (ALOS) in hotels is four nights from Q4 2020 to Q1 2022 and is expected to remain the same in 2023-2024. Revenue per available room (REVPAR) is expected to decline in Q1 2023 and peak in Q3 2023. However, projections for 2023 and 2024 show continued growth in tourism revenue (TR) in the UAE.

O artigo tem por objetivo apresentar uma ação que envolveu o exercício da pesquisa e da produção de matérias didático-pedagógicos, realizada pelos/as professores/as indígenas em Pernambuco, no período compreendido entre 2021-2022. Os/as professores/as indígenas são oriundos dos seus territórios e trazem consigo vivências e respectivas histórias, culturas e tradições. Por mais de 500 anos, os povos indígenas foram invisibilizados na história brasileira e sem os registros escritos substanciais das suas lutas, resistências e conquistas. Com isso, a importância da realização das produções dos materiais didático-pedagógicos pelos povos indígenas consiste na promoção da Cultura dos Direitos Humanos e da Educação em Direitos Humanos, em prol da autonomia e o fortalecimento identitário dos povos, retirando-lhes da invisibilidade e/ou vulnerabilidade histórica. Para realizar tal discussão, apontamos alguns aspectos para o desenvolvimento dessas questões que balizaram este estudo, como referenciais teóricos sobre produção de material didático-pedagógico; a importância de ser professor/a indígena e pesquisador/a na produção de material didático-pedagógico; e, por fim, a discussão sobre produção de material pedagógico pelos/as professores/as indígenas. O percurso metodológico traz uma discussão teórica referente à produção de material pedagógico em si, sobre o percurso de pesquisa que um professor/a indígena que realiza ao produzir esse material, assim como a formação desse professor/a, seja inicial ou a continuada. A fundamentação teórica é promovida por meio de pesquisa sobre a bibliografia existente e, a partir dela, delineamos uma discussão sobre os itens destacados em nosso objetivo. Os resultados esperados é o entendimento de como a produção de material pedagógico pelos professores indígenas pode promover a autonomia intelectual e o fortalecimento identitário do seu povo, como também oportunizar ao não indígena o desenvolvimento da formação dos seus estudantes voltadas para o fortalecimento à promoção do respeito aos Direitos Humanos, principalmente, àqueles adstritos às diversidades e diferenças.
