Transportation problem  are one of the linear Programming 
Problem
?
The objective is to minimize the cost of distribution a product 
from a no of sources or origin to a  no of destination in such a 
manner to minimize the total transportation cost.
For example
? Manufacturer has three plants P
1
, P
2
, P
3
 producing same 
products. 
?
 From these plants, the product is transported to three 
warehouses W
1
, W
2
 and W

 Each plant has a limited capacity, and each warehouse has 
specific demand. Each plant transport to each warehouse, but 
transportation cost vary for different combinations.
