A third of a century ago, management guru Peter Drucker called logisti
cs the last great unexplored continent of business. This is no longer
true. While transportation is the largest component of logistics, orde
ring costs, carrying costs, warehousing costs, and administrative cost
s are nontrivial. Corporations and academics now have departments to h
andle the logistics functions. Transportation has been subsumed, in ma
ny cases, by these broader departments. Managing the supply chain-from
raw material assembly, to work in progress, to the physical distribut
ion of the final product or service-is the essence of business logisti
cs. The field has its quantitative side, with many models that minimiz
e costs and maximize profits. A growing area is the qualitative side,
which emphasizes management awareness of the logistics chain.
