Synthetic Aviation Spare Parts Demand Inventory and Stockout Dataset for Supply Chain Analytics and Digital Twin Research

This dataset provides a reproducible synthetic panel of aviation spare parts demand, inventory, stockout, flight cycle, and supplier lead time observations for research in aviation maintenance supply chains, spare parts forecasting, inventory analytics, and digital twin applications. The dataset contains 12,960 part location month observations covering 60 synthetic spare parts, three stocking locations, and a 72 month period from January 2018 to December 2023. The parts are divided into fast moving, slow moving, and intermittent demand classes. Monthly demand is generated using a zero inflated Poisson process with a synthetic flight cycle driver incorporating seasonal variation and a mild temporal trend. Inventory states and stockout indicators are generated using a reorder point replenishment simulation, while supplier lead times are sampled from 15, 30, 45, and 60 days. The dataset is accompanied by the exact Python generation script and validation scripts required to reproduce and verify the deposited data.

Do not describe this as real airline operational data. Your README and generator clearly establish that it is a synthetic dataset. Once Mendeley gives you the DOI, send me the DOI or the Mendeley metadata page. I can then check the published record against the code/CSV and help you make the final manuscript Data Availability Statement, Code Availability Statement, and repository citation exactly consistent with the DOI.
