Abstract The adverse physiological effects of flight, caused by ascent to altitude and its associated reduction in barometric pressure, have been known since the first manned balloon flights in the 19th century. It soon became apparent that the way to protect the occupant of an aircraft from the effects of ascent to altitude was to enclose either the individual, or the cabin, in a sealed or pressurized environment. Aircraft emergency oxygen systems are emergency equipment fitted to pressurized commercial aircraft, intended for use when the cabin pressurization system has failed and the cabin altitude has climbed above a safe level. It consists of a number of individual yellow oxygen masks stored in compartments near passenger seats and near areas like lavatories and galleys, and an oxygen source, like a centralized gaseous cylinder or decentralized chemical oxygen generator. For continuous supply of oxygen to a fleet of aircraft, it is essential to forecast the demand of oxygen cylinders. For practical application, moving average and exponential smoothing models were used. Such prediction improves the restock processes while complying with the civil aviation and storage safety rules.
