Logistics is the art and science of managing and controlling the flow
of goods, energy, information and other resources like products, services,
and people, from the source of production to the marketplace. It is difficult
to accomplish any marketing or manufacturing without logistical support.
It involves the integration of information, transportation, inventory,
warehousing, material handling, and packaging. The operating responsibility
of logistics is the geographical repositioning of raw materials, work
in process, and finished inventories where required at the lowest cost
