The accumulation operation is the most fundamental method for processing data in grey models, playing a decisive role accuracy of model predictions. However, traditional forward does not adhere to principle prioritizing new information. Therefore, we propose novel fractional reverse accumulation, which increases coefficient fully utilize information carried by latest data. This led development model, termed FGRM(1,1). was validated using renewable energy consumption from France, Spain, UK, and Europe, results demonstrated that FGRM(1,1) outperformed other models terms simulation error, prediction comprehensive error. predictions indicated significant growth France moderate robust Europe overall. These findings highlight effectiveness proposed utilizing provide insights into transition emission reduction potential Europe.

Purpose Meteorological disasters pose a significant risk to people’s lives and safety, accurate prediction of weather-related disaster losses is crucial for bolstering prevention mitigation capabilities addressing the challenges posed by climate change. Based on uncertainty meteorological sequences, damping accumulated autoregressive GM(1,1) model (DAARGM(1,1)) proposed. Design/methodology/approach Firstly, terms system characteristics are added damping-accumulated model, partial autocorrelation function (PACF) used determine order terms. In addition, optimal parameters determined optimization algorithm. Findings The properties were analyzed in stability solution error restored value. By fitting predicting affected comparing them with results four other grey models, validity new was verified. Originality/value dynamic trend factor introduced into generation operator so that can flexibly adjust accumulative sequence. On basis term take account influence previous data, which more descriptive development time series itself increases effectiveness model.

This paper aims to provide insights into the future trends for marine industries in China, by forecasting added value key sectors and then offering tailored policy recommendations. Those economic indicators at industry level are characterized small sample sizes, sectoral heterogeneity, irregular fluctuations, which require a specialized methodology handle data features predictions each industry. To address these issues, conformable fractional grey model ( CFGM ), integrates accumulation with model, is applied proven effective through accuracy robustness tests. First, results from multi-step experiments demonstrate that significantly outperforms traditional statistical, machine learning models, models context of predictions, an average improvement 32.14%. Second, stability predictive values generated further verified Probability Density Analysis PDA ) multiple comparisons best MCB tests, thereby ruling out possibility accurate result mere chance. Third, used estimate across industries, accompanied suggestions ensure sustainable development economy.
