Abstract: Abstract Accurate prediction of software faults is essential for effective maintenance and improving overall reliability. This study presents a hybrid model that integrates autoregressive integrated moving average (ARIMA) with long short-term memory (LSTM) networks to enhance fault prediction accuracy. The ARIMA part effectively identifies linear patterns and trends in time series data, while the LSTM component captures complex nonlinear relationships and dependencies. Evaluation on three real-world datasets from open-source software projects shows that the hybrid approach outperforms both standalone ARIMA and LSTM models. The advantages of this model include enhanced decision-making capabilities, minimized downtime, and improved user satisfaction. This research provides a significant contribution to the field of software reliability forecasting, offering practitioners a robust tool for ensuring software dependability and enabling proactive strategies.
