order arrival

This second definition, which is often used in operations management textbooks, is based on the idea of not running out of stock during the time between re-ordering and order arrival (the leadtime).

Captain Cordobes and Sergeant Parsons were everywhere, running in and out of the LZ, ordering arrivals into one of the two hangars for shelter, moving equipment, resetting flares, inventorying ammunition as it was unloaded - all in the blistering night's cold.
