Employing Linear 

Programming

L

inear  programming  made  a  first  appearance  during  World  War  II  when 

logistics proved critical in maneuvering armies of millions of soldiers, weap-

ons,  and  supplies  across  geographically  variegated  battlefields.  Tanks  and 

airplanes needed to refuel and rearm, which required a massive organizational 

effort to succeed in spite of limitations in time, resources, and actions from the 

enemy.

You can express most of these military problems in mathematical form. Mathe-



matician George Bernard Dantzig, who was employed in the U.S. Air Force Office 

of  Statistical  Control,  devised  a  smart  way  to  solve  these  problems  using  the 



simplex algorithm. Simplex is the core idea that created interest in numerical opti-

mization after the war and gave birth to the promising field of linear program-

ming. The availability of the first performing computers of the time also increased 

interest, rendering complex computations solvable in a new and fast way. You can 

view the early history of computing in the 1950s and 1960s as a quest to optimize 

logistical  problems  using  the  simplex  method  and  applying  both  high-speed 

computers and specialized programming languages.
