Abstract

Effective inventory supervision aids modern supply chain operations. However, established methods of forecasting often falter when faced with ever-changing demand, multiple seasons, and promotional peaks, resulting in either stock surplus or shortage, both of which are costly. This study introduces a forecasting methodology that combines Facebook Prophet, a time-series forecasting tool, and Reinforcement Learning (RL) for inventory optimisation. Prophet analyses and forecasts demands by recognising the intricate temporal attributes in the historical sales data, while RL uses these forecasts to continuously refine ordering policies, inventory holding, and shortage costs. The experiments on retail datasets confirm that the new system decreases the forecasting errors by 25% when compared with ARIMA and LSTM and improves inventory service levels by 15–20%, all while cutting the overall inventory expenses. These results underscore the significance of merging statistical forecasting and intelligent decision-making and provide a utilitarian methodology for supply chains to tackle demand and operational variability.
