Question
What is transportation problem?
Solution
The transportation problem deals with transporting goods from a source to a destination by a minimum cost.
Description: A Manufacturer has a number of factories which produces goods at a fixed rate.
He also has a number of warehouses, each of which has a fixed storage capacity.
There is a cost to transport goods from a factory to a warehouse.
Find the transportation of goods from factory to the warehouse that has the lowest possible cost.
Example:
Factories: A1 makes 5 units
A2 makes 4 units
A3 makes 6 units
Warehouses: b1 can store 5 units
b2 can store 3 units
b3 can store 5 units
b4 can store 2 units
Transportation costs:
b1 | b2 | b3 | b4 | |
A1 | 5 | 4 | 7 | 6 |
A2 | 2 | 5 | 3 | 2 |
A3 | 6 | 3 | 4 | 4 |
