  • Transportation Model is a special case of LPP(Linear Programming Problem) in which the main objective is to transport a product from various sources to various destinations at total minimum cost.

  • In Transportation Models, the sources and destinations are known, the supply and demand at each source and destinations are also known.

  • It is designed to find the best arrangement for transportation such that the transportation cost is minimum.

For example:

  • Consider three companies (Company1, Company2 and Company3) which produce mobile phones and are located in different regions.

  • Similarly, consider three cities (namely CityA, CityB & CityC) where the mobile phones are transported.

  • The companies where mobile phones are available are known as sources and the cities where mobile phones are transported are called destinations.
