Logistics

An army marches on its stomach.

Decision theory can be pursued not only for the purposes of building foundations for political economy, or of understanding and explaining phenomena that are in themselves intrinsically interesting, but also for the purpose of offering direct advice to business and governmental decision makers. For reasons not clear to me, this territory was very sparsely settled prior to World War II. Such inhabitants as it had were mainly industrial engineers, students of public administration, and specialists in business functions, none of whom especially identified themselves with the economic sciences. Prominent pioneers included the mathematician, Charles Babbage, inventor of the digital computer, the engineer, Frederick Taylor and the administrator, Henri Fayol.
During World War II, this territory, almost abandoned, was rediscovered by scientists, mathematicians, and statisticians concerned with military management and logistics, and was renamed “operations research” or “operations analysis.” So remote were the operations researchers from the social science community that economists wishing to enter the territory had to establish their own colony, which they called “management science”.

Hannibal excelled as a tactician. No battle in history is a finer sample of tactics than Cannae. But he was yet greater in logistics and strategy. No captain ever marched to and fro among so many armies of troops superior to his own numbers and material as fearlessly and skillfully as he. No man ever held his own so long or so ably against such odds. Constantly overmatched by better soldiers, led by generals always respectable, often of great ability, he yet defied all their efforts to drive him from Italy, for half a generation. … As a soldier, in the countenance he presented to the stoutest of foes and in the constancy he exhibited under the bitterest adversity, Hannibal stands alone and unequaled. As a man, no character in history exhibits a purer life or nobler patriotism.
