Transportation theory (mathematics)
（重定向自Transportation problem）
In mathematics and economics, transportation theory is a name given to the study of optimal transportation and allocation of resources.
The problem was formalized by the French mathematician Gaspard Monge in 1781.
In the 1920s A.N. Tolstoi was one of the first to study the transportation problem mathematically. In 1930, in the collection Transportation Planning Volume I for the National Commissariat of Transportation of the Soviet Union, he published a paper "Methods of Finding the Minimal Kilometrage in Cargo-transportation in space".
