The term "logistics" originates from the ancient Greek "λόγος" ("logos"—"ratio, word, calculation, reason, speech, oration"). Logistics is considered to have originated in the military's need to supply  themselves with arms, ammunition and rations as they moved from their base to a forward position. In  ancient Greek, Roman and Byzantine empires, there were military officers with the title ‘Logistikas’  who were responsible for financial and supply distribution matters.

The Oxford English dictionary defines logistics as: “The branch of military science having to do with procuring, maintaining and transporting material, personnel and facilities. 

"Another dictionary definition is: "The time related positioning of resources.

"As such, logistics is commonly seen as a branch of engineering which creates "people systems" rather  than "machine systems"....
